Engine Coolant/Water in Transmission
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2004 Oldsmobile Bravada, 2004 GMC Envoy XUV, 2004 GMC Envoy XL, 2004 GMC Envoy, and 2004 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The antifreeze or water will deteriorate the seals, gaskets and the glue that bonds the clutch material to the pressure plate. Both conditions may cause damage to the transmission.
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 nylon parts (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.
