Torque Converter Cleaning & Inspection

If installing a new torque converter continue with Substep 2 of Step 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 a suitable torque converter/fluid 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 transaxle. 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. For additional information, refer to TRANSMISSION FLUID COOLER - BACKFLUSHING & CLEANING .
3. All cooler lines must be thoroughly cleaned by backward and forward flushing. For additional information, refer to TRANSMISSION FLUID COOLER - BACKFLUSHING & CLEANING .
4. All cooler bypass valves (CBV), if equipped, must be thoroughly cleaned.
5. Carry out the Transmission Fluid Cooler Flow Test. For additional information, refer to 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. For additional information, refer to REMOVAL & INSTALLATION .
7. If installing new cooler, use only factory-approved parts.
