Commander 2WD V8-4.7L (2008)
Use the following steps to have the TCM learn the Alt 2C CVI.
1. Accelerate the vehicle through 88 km/h (55 mph) at a steady 10-15 degree throttle opening and perform multiple 4-5 upshifts.
2. Repeat STEP 1 until the 4-5 shift become smooth and the Alt 2C CVI become stable. There is a separate 2C volume used and learned for 4-5
shifts, 2CA. It is independent of the 2C CVI learned on 3-2 kickdowns.
