Aussie Hoons Develop Nissan GT-R Launch Control Fix
Nissan GT-R: Aussie Hoons Develop Nissan GT-R Launch Control Fix
We all know and love thw 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 hooing cop cars.

Australian gearbox gurus Pfitzner Performance Gearboxes (PPG) have completed their first Nissan GT-R GR6 gearbox upgrades in the form of a drop in first gear replacement. You can see it pictured about sitting next to a standard GR6 first gear.
You can tell just by looking at this picture the basics of this upgrade, a much wider gear to increase strength. The main cause of gearbox failures occurs on the teeth of the first gears after extreme stress. Initially fractures develop and eventually teeth give way. Once one tooth is gone the rest follow like dominoes.
To follow on from this, PPG plan some gear upgrades for big horsepower cars as well as a 1st through 4th gear upgrade set.

+1. Problem is that Nissan already dropped launch control, so making the stronger gears really only helps people who bought the first batch of GT-Rs. I'd be curious to see how long these gears last as well.

to add to that...
from my understanding, the transmission failed because it was repeatedly given to much stress at launch due to the car being 4wd and a lot of wheel hop, correct?
if so, wouldnt the only solution to this be to convert the car to 2wd as well as replacing these gears?
