Procedure To Learn The 1st 2-3 Shift After A Restart Or Shift To Reverse
WARNING: This page does not describe the selected car, but rather 120 other vehicles, including the 2002 Saturn Vue, 2002 Saturn SL2, 2002 Saturn SL1, 2002 Saturn SL, and 2002 Saturn SC2. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The transmission fluid temperature must be above 80°F (27°C).
Use the following steps to have the TCM learn the 1st 2-3 shift OD Clutch Volume Index (CVI).
- With the engine running, select Reverse gear for over 2 seconds.
- Shift the transmission to Drive and accelerate the vehicle from a stop at a steady 15 degree throttle opening and perform a 2-3 shift while noting the OD CVI. During the shift, a different value may appear on the DRBIII® screen, which is the 1st 2-3 OD CVI.
- Repeat steps 1 and 2 until the 1st 2-3 upshift becomes smooth and the 1st 2-3 OD CVI stabilizes.
