Torque Converter Cleaning and Inspection

Torque Converter Cleaning And Inspection

1. If the torque converter is being replaced, continue with sub-step 2 of Step 2.
2. If the torque converter is not being replaced the following procedures must be carried out:
1 The torque converter must be thoroughly cleaned.
^ Torque converter with drain plugs may be cleaned by using a suitable torque converter/transmission fluid cooler cleaner.
^ Torque converter without drain plugs may be cleaned by hand. Partially fill the torque converter using only the 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 the transmission, and install.

2 The in-tank and auxiliary coolers must be thoroughly cleaned by forward and backward flushing.
3 The 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, the auxiliary fluid cooler, cooler bypass valve, and or cooler lines may require installation of new components.
5 If the internal cooler needs to be replaced, refer to cooler. If the auxiliary cooler needs to be replaced, refer to auxiliary cooler. If the Cooler Bypass Valve (CBV) needs to be replaced, use only factory-approved service parts.
