Engine Coolant/Water in Transmission
WARNING: This page is about a different car, the 2005 Cadillac STS. However, it is still accessible from the selected car via links, so may be relevant.
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.
