Since less energy in stored in the mount system and suspension system, the reaction bump during garage shifts will be reduced without compromising vehicle performance. For the N-D garage shift, such as after key-on when a shift lever is positioned in drive, a vehicle shifts to second gear (or some other higher gear) which provides reduced torque applied to the powertrain mount system and vehicle suspension system. For the D-N garage shift, as a vehicle slows down to a zero speed with the brake on, the vehicle is shifted into a higher gear. As the vehicle starts to launch, the vehicle is immediately shifted back to first gear, launching the vehicle with its first gear ratio. | 10-30-2008 |
