Torque Converter Cleaning And Inspection
1. If a new torque converter is being installed, continue with Substep 2 of Step 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 in this section.
3. All cooler lines must be thoroughly cleaned by backward and forward flushing. For additional information, refer to Transmission Fluid Cooler — Backflushing and Cleaning
in this section.
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 in this section.
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 Section 307 - 02 .
7. If new coolers are to be installed, use only factory approved service parts.
