Unfortunately, "Chrysler New Yorker" only exists on four-track cassette tape, and my ol' Tascam Porta 01 died years ago. That means you don't get to hear that fine song, which thrilled dozens of Japanese college radio fans during the late 1980s. What you do get is the "music video" for the Murilee Arraiac song "Hajoi Hotai," which features the circa-1990 replacement of a 2-speed Powerglide with a junkyard Turbo Hydramatic 350 3-speed in a 1965 Impala. That's me with the Plumber Butt on the right left, and my friend ChunkyDeath on the right. Note ChunkyDeath's innovative "floor jack leg pump" maneuver.

<![CDATA[6R140 TorqShift Six-Speed Transmission]]> Ford designed their all-new 6R140 TorqShift Six-Speed Transmission to meet the power from both the 6.7 liter Power Stroke and the 6.2 liter gasoline V8, a unique proposition considering diesels provide their power at low speeds and gasoline motors have much higher red lines than diesels. The new six-speed does this by combining tried and true systems with modern manufacturing capabilities.

According to Ford, the trick to the transmission is augmenting a traditional Lapelletier powerflow with a sintered, powder metal carrier for the planetary gearset. It allows high strength in a complex part able to stand up to both the high speed and high torque requirements of both engines. The common transmission allows Ford to focus as much on the shifting and control strategy as it does the mechanics, and as a result this trans packs some nifty tricks.

The six gears are spread out to provide low end grunt and high end efficiency, but with a degree of control truck transmissions rarely get. The trans can be operated in traditional automatic or a fully manual mode, where gear selection locks the torque converter and hold the gear as long as the driver sees fit. It'll bog all the way down to 900 RPM before shifting out.

The 6R140 also takes a page from the F150 and uses a tow haul mode which improves control and braking in hilly situations. Perhaps the neatest trick comes with the diesel application. A honest to God power take off will be available for heavy duty applications like driving salt spreaders, sweepers, and any manner of mechanical what-have-you. See, new transmission can still get old tricks.

NEW TORQSHIFT SIX-SPEED TRANSMISSION HARNESSES, CHANNELS INCREASED POWER FROM NEW FORD ENGINES

* The new 6R140 heavy-duty TorqShift® six-speed automatic transmission is specifically designed to handle the increased torque produced by the all-new Ford-designed, Ford-engineered and Ford-built 6.7-liter Power Stroke® V-8 turbocharged diesel and also will be mated to the all-new 6.2-liter V-8 gasoline engine
* The new TorqShift transmission's wider gear span, advanced controls that optimize the shift schedule, reduced parasitic friction losses and lower-rpm torque converter lock-up all contribute to improving fuel economy in the 2011 Ford Super Duty
* The new 6R140 transmission provides full SelectShift™ capability and is available with segment-exclusive Live Drive Power Take Off (PTO) with the new diesel engine

DALLAS, Sept. 24, 2009 – All-new diesel and gasoline engines are key reasons why the 2011 Ford F-Series Super Duty maintains best-in-class towing and payload and adds enhanced off-road capability. Managing the increased horsepower and torque is the all-new 6R140 heavy-duty TorqShift® six-speed transmission, which delivers power quickly and seamlessly while maximizing fuel economy.

"Our new transmission perfectly complements our new diesel and gasoline engines to give the customer the best powertrain for Super Duty applications," said Al Bruck, 6R140 transmission engineering manager. "Rigorous testing ensures our transmission and powertrain is up to the challenge of even our most demanding Super Duty customers. Overall, the 6R140 heavy-duty TorqShift six-speed transmission enables greater customer capability, efficiency and control than ever before."

Creating a transmission to serve both diesel and gasoline engines in a Super Duty application is a challenging proposition because the gearbox needs to deliver the substantial low-rpm torque produced by the diesel engine and efficiently use the higher rotational speeds of the gasoline engine. The solution was to use a proven architecture, but adapt it for heavy-duty use.

Lepelletier powerflow: New application of tried-and-true system
Ford's 6R140 TorqShift transmission uses a Lepelletier-style powerflow, which is a proven technology in rear-wheel-drive vehicles but not typically used with larger diesel engines. A key benefit of the Lepelletier architecture is that it reduces the complexity in connecting the gearsets and clutches. The six speeds require only five clutches, and the speeds of the clutches relative to one another are low, increasing the efficiency of the system.

To handle the torque of the 6.7-liter Power Stroke V-8 turbocharged diesel, Ford strengthened the system by employing a unique powder-metal carrier in the compound Ravigneaux planetary gearset. The carrier consists of four pressed powder-metal components sinter-brazed together to form a rigid, power-dense structure. This solution ensures robustness and makes the architecture compatible with both the diesel and gasoline engines. A Ford-patented rocker one-way clutch is integrated with the carrier and helps improve 1-2 shift quality through the gearset.

"With this architecture, the new transmission can handle the enormous low-end torque produced by the new diesel engine as well as the high speeds produced by the new gas engine," Bruck said. "The sinter-brazed gearset enables more torque capacity and greater engine speed capability."

A deep first gear ratio and two overdrive gears create a wider ratio span. This, combined with available lower axle gear ratios and a control system that automatically selects the most efficient shift schedule, provides an outstanding combination of pulling power and fuel economy.

"Our first gear ratio is a fair amount deeper than our competitors, so customers will get improved off-the-line performance," Bruck said. "The six ratios we've selected provide greater overall span and better overdrive performance, which reduces engine speed in highway conditions and improves fuel economy."

"Because we have six gears, we make smaller steps gear to gear, which helps keep the engine in its sweet spot in terms of performance and efficiency."

Six-speed gearbox offers best of automatic, manual transmissions
The 6R140's heavy-duty TorqShift six-speed transmission balances convenience and control by automatically shifting during routine operation and also allowing complete manual control. It features SelectShift Automatic transmission functionality, which includes both Progressive Range Select and manual functions.

With Progressive Range Select, a toggle on the shift lever allows the customer to reduce the range of available gears while in Drive. When the customer "taps" down into Range Select mode, the display shows the available gears and highlights the current gear state. This feature allows the driver to limit use of upper gears when heavily loaded or while towing on grades.

For full manual function, customers also can pull the shift lever into "M" for manual mode and use the same toggle switch to select the gear desired. The display will show the selected gear, and the control system will lock the torque converter and hold that gear for a full manual transmission feel.

Proven Tow Haul Mode: Taken to the next level
The 6R140 transmission also features standard enhanced Tow Haul capability, which provides better control when hauling a heavy load or towing a trailer, especially when going down grades. The improved system uses an array of sophisticated electronic sensors to better predict the driver's need for a downshift to provide engine braking and enhanced control.

Torque converter provides connected feel and better efficiency
The torque converter of the 6R140 transmission is designed to be accurately controlled and efficient. A closed-piston design provides precise control of the lock-up clutch. Its torque multiplication is matched with the rest of the powertrain for better off-the-line performance, but that's only the start. Once under way, a long-travel, high-capacity turbine damper allows the torque converter to dampen out the extreme torsional force produced in particular by the new, more powerful diesel engine.

"This damper allows us to lug down to 900 rpm while our competitors lug to around 1,100 rpm," Bruck said. "This technology allows us to stay locked more, which means the engine can run at a lower rpm and get better fuel economy."

Live Drive PTO: Power whenever the engine is running
Another example of taking a proven technology and applying it to the Super Duty to improve customer productivity is the availability of segment-exclusive Live Drive PTO (Power Take Off). On 2011 Ford Super Duty diesels with the PTO prep option, the PTO output gear is linked through the torque converter to the engine crankshaft. This allows the transmission to power auxiliary equipment such as snowplows, aerial lifts, cement mixers, tow truck lifts or dump trucks. The power is available any time the engine is running.

Pioneered on agricultural applications, the Live Drive feature is particularly useful when mobile PTO function is required during start-stop operations, such as salt spreading or snow plowing. "A fully functional Live Drive mobile PTO will allow Super Duty customers to take full advantage of the equipment on their trucks," said Bruck.

Durability testing in the lab and on the road
The 6R140 transmission has undergone extensive durability and reliability testing in Ford's supercomputers, in the lab and on the road to ensure customer satisfaction. Extensive computer-aided engineering was completed before the hardware phase began for improved efficiency in terms of time and reduced failures.

Once the analysis was complete, physical testing in the laboratory included running the new transmission 24/7 while mated to both engines to help ensure real-world durability.

The transmission was rigorously tested – at unloaded and maximum GCW (Gross Combined Weight) duty cycles – for 250,000 equivalent miles to replicate what the most demanding, harshest Super Duty customer can dish out.

The 6R140 heavy-duty transmission will be built at the Sharonville (Ohio) Transmission Plant.

Making 520HP at the wheels on a dyno is no joke for a turbocharged four-cylinder, especially from a car that never got much respect during its life, but this Colt manages it at a crushing 44 PSI of boost. That built engine wasn't hooked up to a particularly fortified transmission though, so this impressive failure was pretty much inevitable. Very nicely done sirs. (Hat tip to Sean!)

<![CDATA[Aussie Hoons Develop Nissan GT-R Launch Control Fix]]> We all know and love the new R35 GT-R, but what about the reported transmission failures when using the launch control feature? One Australian company has a solution.

Pfitzner Performance Gearboxes (PPG) out of Australia wants R35 GT-R owners to have their cake and eat it too. They’re readying their first GT-R gearbox upgrade to hopefully solve the issue some owners are experiencing when over-using the launch control feature. The GR6 gearbox is a beefy unit from the factory, but it seemingly has its faults. According to PPG, the main reason for the GT-R transmission failures occurs on the teeth of the first gear when put under extreme stress. Fractures develop after few hard launches and eventually the teeth give way.

The company will soon offer a drop-in first gear replacement featuring a much wider gear to increase the strength of the unit. A follow up set will include gear upgrades for high-horsepower cars and a 1st through 4th gear upgrade set. We only hope Nissan will look to this option, rather than dropping launch control altogether. This is apparently what Australians are doing when not hooning cop cars.

<![CDATA[GT-R Owner Busts Tranny Using Launch Control, Nissan Claims Issue Not Covered Under Warranty]]> Someone claiming to own a Nissan GT-R has proclaimed on the North American GT-R Owners Club forums (NAGTROC) that his GT-R's transmission has broken after multiple uses of the vehicle's launch control function. The owner says that when the vehicle was then brought to the Nissan service center, where he was told the destroyed transmission would not be covered under warranty due to the car being driven too often with the Vehicle Dynamic Control (VDC) shut off.

Another forum member clarifies that "you have to turn off VDC to activate LC, and you have to sign a paper saying your warranty is voided if you turn of VDC, and while VDC is off, you cause damage. It is clearly stated in the manual/warranty, as well as is put into writing and you have to sign, when you pick up the car." Below the jump, the personal account, in the owner's words, from a thread titled "do not launch your gtr or take the vdc off, time to bend over guys its gonna hurt."

I was driving my gtr two weeks ago and I heard a loud noise coming from the rear. I turned immediately had my gtr towed to crown nissan st. petersburg fl. They didn't touch my car only called some techs from tennessee to look at the car and record the noise, 4 days later two guys from japan to download some info from the car then left. Then I get a call from the dealer to tell me the news, and they told me that the car was driven without vdc too much and nissan will not warranty the transmission which they said was destroyed, I asked them how much to fix it they told me 20k, no freaking way I will pay 20k on top of what i just paid for the car. I called the gtr number and also talked to nissan consumer affairs got nowhere, now the car is sitting at the dealer. I know we shouldn't launch the car but why own it if you cant use this function, don't sell a car that goes 0-60 in 3.4 sec if the only way you can achieve this speed is to void the warranty , false advertising. Here is the bad news people were fearing it has happened to me and Nissan has told me there are already three people in my shoes, if you are one of these people email me, we have got to get together on this. Just think if any of you guys have taken the vdc off just a few times you have already voided your warranty, good luck what a joke nissan.

Since poor grammar doesn't lead to high credibility, we're wondering what the owner isn't telling us. At the same time, it seems odd that Nissan would build a supercar with a significant part like the transmission unable to handle hard use. What do you think? Is this guy a moron that hooned his car beyond the reasonable limits, or does he have a valid point to his complaints? [read the entire thread at NAGTROC] (Hat tip to Michael!)

<![CDATA[Automatics Closing Fuel Economy Gap On Manuals; Engines, Electronics Lending A Hand]]> In a stringer piece for the Detroit News, Rex Roy makes the observation that automatic transmissions are finally beginning to catch up to stick shifts in fuel economy. While we say "it's about damn time," considering automatics make up more than 90% of the US new vehicle market, we simultaneously lament that same fact. Also, we think photog-cum-journo Roy misses out on an important component of the improvement: The interface between engine and transmission and the technologies that make the entire powertrain system more efficient. Join us after the jump for a look at why it's not just the two extra gears in your slushbox doing all the work.

The first thing that had to happen for automatics to get closer to manuals in fuel economy was an improvement in automatic transmission design. Advances like variable line pressure and the addition of more than four forward gears were far too long in coming to mass-market vehicles in this country. But, five- and six-speed autoboxes are finally becoming the norm. Even the retro four-speed automatics many domestics saddle their low-end models with now have variable line pressure, which reduces the amount of power needed to drive the transmission. All these improvements lead to better efficiency and reduced fuel consumption.

But the key, as with so many modern advances, has been in the software controlling the engine/transmission relationship. Old transmissions used a vacuum modulator and a mechanical governor to adjust shift points. New electronically controlled automatics take advantage of vast improvements in processor power to tailor shifts, internal pressures, and torque converter lockup to extract the maximum amount of efficiency possible. The engine helps, though: Cylinder deactivation, like Chrysler's MDS and GM's Active Fuel Management, only works effectively through constant communication with the transmission's requirements. You don't feel any of it happening: You just notice that your new automatic car gets close to the same mileage as your old 5-speed manual beater.

So, Rex Roy, we agree that automatics have made exponential improvements in recent years. But let's not give short shrift to the software wizardry and all the black boxes that allow an engine and a transmission to function as an integrated modern powertrain. [Detroit News; Photo Credit: ZF]

<![CDATA[What's The Proper Orientation Of Manumatics?]]> Today's review car, which you can read about above, features three ways to clutchlessly shift gears. You can push/pull the thumb buttons, push/pull the shifter or just let the automatic do its thing on its own. Assuming you've given in and gotten a slushbox with the manual mode, we're going to give you credit and assume you'll mostly choose the gears yourself. This brings up the question of which is the proper orientation? Wes and I got into a long debate about this ourselves, not being able to agree if it should follow the racer model of forward (away from you) for downshifts and towards you for upshifts, or do the inverse.

I tend to think that the inverse is more intuitive for those used to driving a manual, but I may be in the minority there. We could agree, however, that transmissions that include the paddles/buttons on the steering wheel should be oriented laterally (left/right) as opposed to forward/back. Wes ran into this problem with the 2009 BMW X6, which required pushing or pulling with no regard for horizontal layout, causing much confusion. Which is right? Why is Wes wrong? Why am I wrong? Why, why, why, why, why!?!

<![CDATA[Real $500 Race Cars Have Manual Transmissions... And Inner-Tube Shifter Boots!]]> When we started out to build a V8-powered Volvo 244 for the May 10-11 24 Hours of LeMons race, most of the team members assumed we'd be using the good ol' C4 automatic transmission. You know, automatics are way easier to swap, with no troublesome clutch linkage to futz with. But Crew Chief Hellhammer (formerly known as Dave) pointed out that he's built plenty of manual-equipped rods, and then he directed our attention to several Ford V8-compatible T-5 5-speeds (and no C4s) sitting in the weeds behind his shop (he's been working on a '57 Ford project, so his stash-o-parts is heavy on Ford running gear). With our minds filled with images of slushboxes overheating and dying at last year's Altamont race, we decided to go with three pedals instead of two... then held our collective breath when it came time to make it happen for real.


V8olvo_Trans_Xmember.jpg
As it turned out, this is a ridiculously easy swap (well, by the standards of weird engine swaps, that is). The 5-speed shifter even lined up perfectly with the hole for the Volvo's automatic shifter. A bit of crossmember modification and it was in place.

V8olvo_Trans_Pedals.jpg
What really had us worried was the potential nightmare of rigging up clutch linkage. We grabbed a Volvo clutch pedal and cable assembly out of a manual-trans 244 at the junkyard and settled down for what threatened to be agony-packed days of fabrication.

V8olvo_Trans_Clutch.jpg
But no! The Volvo cable hooked right up to the Ford transmission and worked fine. We were stunned. Of course, all the time we saved on this project was promptly eaten up by a thousand other details, but we aren't complaining. We forgot to grab a shift boot in the junkyard, so we fabricated a crude bracket and zip-tied a piece of inner-tube rubber in place. Now if we can just keep from breaking U-joints and differentials at the track...

<![CDATA[M-Power! Five Things We Know About BMW's Dual Clutch Transmission]]> Add another true automanual tranny to the growing list. Call it the M double-clutch transmission with DriveLogic. It's BMW's new 7-speed switchgear that's shipping with the new M3s, and likely will replace the divisive, largely poky and cumbersome — that is, without some serious futzing — M-Sequential (SMG / SMG II) automated manual. The SMG system uses a high-pressure hydraulic actuator to shift gears, with the latest version (i.e., SMG II) offering five automatic modes and six manual modes and shift times in around 80 miliseconds. In dual-clutch systems, like BMW's new system and VW/Audi's DSG, one clutch handles gears 1, 3, 5, 7 (and reverse) and the second handles 2, 4, 6 — they work alternately, engaging and disengaging in a complex dance that allows for uninterrupted upshifts at speeds of a few milliseconds. An algorithm takes into account throttle position, engine speed, road speed and shift mode in use when calculating shift management. What else do we know about the new M double-clutch transmission with DriveLogic? Click through.

1.) It offers the same collection of modes as SMG, allowing the driver to dial in a range of response patterns, from low-torque, second-gear starts on snow and ice, to comfort, to track day.

2.) It's the first dual-clutch box to be designed for engine speeds of up to 9,000 rpm, with a transmission fluid cooler to lengthen component life.

3.) Like the new Nissan GTR (but unlike the latest F1 cars), it has launch control. How does launch control work? Take it, BMW:

...all the driver has to do with the car at a standstill and in driving program S6 is move the sports shift lever to the front and hold it in this position. Then, as soon as the starter flag symbol comes on in the instrument cluster, the driver just presses down the gas pedal to automatically obtain the ideal starting speed on the engine. Pressing down the brake pedal lightly with his left foot, in turn, the driver can prevent the car from rolling forward, and by briefly tipping the cruise control lever he is able to finely adjust the desired starter speed. Then, after letting go the selector lever, the BMW M3 accelerates with optimum performance and with slip on the rear wheels controlled by the clutch — if the driver wishes, all the way to top speed.
4.) Low-speed assistant, gradient detection.

5.) It sounds like a whole lot more fun than SMG.

This old-school auto-parts store has been in the same brick building on Park Street since the 1920s, and now stands as one of the only remaining independent parts stores in northern California. If you go to Lee Auto and ask for, say, a timing-cover gasket for an unknown-origin Ford 289 engine that you bought for $50 from some guy and dropped into your F-100, you won't get a puzzled teenager asking you for the year/make/model so he can punch it into The Computer and give you the wrong part. No, you'll get a genuine parts guy, who will have stories to tell about the 289-powered Comet he used to blow the doors off some dude's Barracuda at City Line back in 1973, and you'll leave with exactly the right part...


...and one of the best things about Lee Auto (which has been my main source of parts and advice since I was a young hoon with my very first car) is that the place is a freakin' gearhead museum. They've got a creaky wooden floor, plaques from East Bay car clubs going back to the 1920s on the walls, 1950s and 1960s stickers completely covering the parts counter, yellowed photos of store-sponsored race cars at the old Fremont Dragstrip, and this vintage Hurst display right up front, where it's been since the Hurst rep dropped it off during Eisenhower's presidency.

<![CDATA[Report: BMW to Launch Dual-Clutch Tranny in M3 Sedan]]> As a leaked dealer memo indicated earlier this year, BMW's set to launch a DSG-style automanual in its new M3. Having seen neither hide nor hair of the new clockworks in Frankfurt, we're moving on to the next report. That is, word from AutoTelegraaf that the new, electromechanical seven-speed — developed with Getrag — dubbed "M DCT" will debut with the M3 sedan. Talk is of faster, smoother shifts than the M5's unwieldy SMG setup. LA or Detroit debut? Place your bets. [AutoTelegraaf via Motor Authority]
