Torque the bolts to 12 Nm (108 lb in).
2. Connect the internal wiring harness connector to the TFP switch.
3. Install the oil pan and transmission internal oil filter. Refer to Oil Pan Replacement (See: Transmission and Drivetrain/Automatic

Note: The FastLearn, adapt, procedure must be performed. This can be done in 1 step using a scan tool. If this procedure is not done, the TCM
adaptive values will be at the settings that it learned for the old components and will be in slow adaptive mode. Under these conditions, it will take
an unacceptably long time for the adaptive values to converge to levels suitable for the new transmission.
4. Perform the FastLearn procedure. Refer to FastLearn Procedure (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing
and Inspection/Programming and Relearning/Allison - Automatic Transmission).
