Learn A Smooth 1-2 Upshift and 3-2 Kickdown

Use the following steps to have the TCM learn the 2C shift volume.

NOTE: The transmission oil temperature must be above 110° F (43° C).

1. With a vehicle speed below 48 km/h (30 MPH) and the transmission in 3rd gear, perform multiple 3-2 kickdowns.
2. Repeat Step 1 until the 3-2 kickdowns become smooth and the 2C CVI becomes stable.
