1. If a new torque converter is being installed, continue with  2.
2. If a new 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 clean automatic transmission fluid specified for transmission, and reinstall.
   2. All in-tank and auxiliary coolers must be thoroughly cleaned by forward and backward flushing. For additional information, refer to TRANSMISSION FLUID COOLER - BACKFLUSHING AND CLEANING .
   3. All cooler lines must be thoroughly cleaned by backward and forward flushing. For additional information, refer to TRANSMISSION FLUID COOLER - BACKFLUSHING AND 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 - BACKFLUSHING AND CLEANING .
   6. If the transmission cooling system fails the Transmission Fluid Cooler Flow Test, a new fluid cooler, cooler bypass valve, and/or cooler lines must be installed. For additional information, refer to TRANSAXLE/TRANSMISSION COOLING .
   7. If new coolers are to be installed, use only factory approved service parts.
