In a bulletin sent out to dealers today, Nissan outlined its plan for transmission changes in all unsold 2009 GT-Rs as well as the upcoming 2010 GT-R. The changes are the first official response to reports of transaxle failure as a result of using the much-hyped launch control system.
We sifted through all the official wording and it boils down to this:
- There are no hardware changes.
- Dealers will reprogram the car's ECU to alter the transmission characteristics during hard launches.
- Launch Control remains, but the maximum allowable engine speed with the VDC system switched off will be reduced from the current 4,500 rpm to between 3,000 and 3,500 rpm. The clutch engagement program will also change to reduce driveline stress, e.g., less abrupt engagement on launch.
- When launching with the VDC on, the new programming will allow for higher engine speeds and a more aggressive clutch engagement than the current setup.
- Nissan reiterated that launching the GT-R with the VDC off is not covered by the warranty.
- A revised customer disclosure form will be issued and required for GT-R sales going forward.
- All GT-Rs worldwide will receive the revised programming.
