Learn A Smooth 4-3 COASTDOWN And Part Throttle 4-3 KICKDOWN
NOTE:
The transmission oil 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 64-97 km/h (40-60 MPH), perform repeated 4-3 kickdown shifts.
- Repeat Step 1 until the UD volume becomes somewhat stable and the shift becomes smooth.
