NOTE: Prior to installing a new transmission or an overhauled transmission with a new main control, record the solenoid strategy identification tag. If a new main control was installed, install the replacement solenoid body tag over the original identification tag. For additional information, refer to Solenoid Body Strategy in this section.

1. NOTICE: Prior to installation of the transmission, lubricate the torque converter pilot hub with multi-purpose grease or damage to the torque converter or engine crankshaft can occur.

54. While driving the vehicle, use the scan tool to verify that the Transmission Fluid Temperature (TFT) has reached a temperature of 88°C (190°F). This will circulate the transmission fluid through the torque converter and the transmission fluid cooling system, eliminating any trapped air in the transmission fluid cooling system.
    • With the engine idling (600-750 rpm) in PARK, verify that the TFT is between 80ºC-85ºC (176ºF-185ºF).
