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.

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!)
