Torque Converter Cleaning and Inspection

1. If installing a new torque converter, continue with Substep 2 of Step 2.
2. If not installing a new torque converter, the following procedures must be done:
1 The torque converter must be thoroughly cleaned.
^ Torque converters with drain plugs can be cleaned by using Torque Converter/Oil Cooler Cleaner.
^ Torque converters without drain plugs 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. Refill the torque converter with new fluid specified for transmission, and reinstall.
2 All in-tank and auxiliary coolers must be thoroughly cleaned by backward and forward flushing.
3 All cooler lines 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 a new fluid cooler, cooler bypass valve, or cooler lines.
7 If installing new cooler, use only factory-approved parts.
