Torque Converter Cleaning And Inspection

If a new or remanufactured torque converter is being installed, continue with Substep 2 of Step 2.
If a new or remanufactured torque converter is not being installed, the following procedures must be performed:
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 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 cooler tubes must be thoroughly cleaned by backward and forward flushing. For additional information, see TRANSMISSION FLUID COOLER TUBES - BACKFLUSHING AND CLEANING .
3. If a new cooler is to be installed, use only factory approved service parts. For additional information, see RADIATOR for cooler in radiator or AUXILIARY TRANSMISSION FLUID COOLER for auxiliary cooler.
