Torque Converter Cleaning and Inspection
1. If a new torque converter is being installed, continue with Substep 2 of Step 2.2. CAUTION: The torque converter drain plug and seal are not reusable. Discard the drain plug and seal, install a new drain plug assembly.
If a new torque converter is not being installed, the following procedures must be carried out:
1 The torque converter must be thoroughly cleaned.
- Torque converter with drain plugs can be cleaned by using Torque Converter/Oil Cooler Cleaner.
- CAUTION: Do not use water based cleaners or transmission damage will occur.
A torque converter without drain can be cleaned by hand. Partially fill the torque converter using only recommended transmission fluid for the applicable transmission. Hand-agitate the torque converter and then thoroughly drain the fluid. Fill the torque converter with new fluid specified for the transmission, and install.
2 All in-tank and auxiliary coolers must be thoroughly cleaned by forward and backward flushing.
3 All cooler tubes must be thoroughly cleaned by backward and forward flushing.
4 All Cooler Bypass Valves (CBV), if equipped, must be thoroughly cleaned.
5 Carry out the Transmission Fluid Cooler Flow Test.
6 If the transmission cooling system fails the Transmission Fluid Cooler Flow Test, install new components as necessary.
7 If new coolers are to be installed, use only factory-approved repair parts.
