If antifreeze or water has entered the transmission, perform the following:
- Disassemble the transmission.
 
- Replace all of the rubber type seals. The coolant will attack the seal material which will cause leakage.
 
- Replace the composition-faced clutch plate assemblies. The facing material may separate from the steel center portion.
 
- Replace all of the washers.
 
- Replace the torque converter.
 
- Thoroughly clean and rebuild the transmission, using new gaskets and oil filter.
 
- Flush the cooler lines after the transmission cooler has been properly repaired or replaced.
