Torque Converter Cleaning and Inspection

Torque Converter Cleaning And Inspection
1. If a new or remanufactured torque converter is being installed, continue with Substep 2 of Step 2.
2. If a new or remanufactured torque converter is not being installed, the following procedures must be carried out:
1 The torque converter must be thoroughly cleaned.
^ 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 for the transmission, and reinstall.

2 A new OTA cooler must be installed when contamination is present in the transmission. Do not try to clean or backflush the OTA cooler or the contamination may be reintroduced into the transmission, causing transmission assembly damage.
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 Carry out the Transmission Fluid Cooler Flow Test.
5 If the transmission cooling system fails the Transmission Fluid Cooler Flow Test, a new fluid cooler (OTA), cooler bypass valve and/or cooler lines must be installed.
6 If new coolers are being installed, use only factory-approved service parts.
