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: Transmission fluid temperature must be above 110°F (43°C).

Use the following steps to have the TCM learn the UD shift volume.

At a vehicle speed between 40-60 MPH, perform repeated 4-3 kickdown shifts.
Repeat step 1 until the UD volume becomes somewhat stable and the shift becomes smooth.
