Torque Converter: Service and Repair

DESCRIPTION
When internal wear or damage has occurred in the transmission, metal particles, clutch plate material, or band material may have been carried into the torque converter and transmission fluid cooler. These contaminants are a major cause of recurring transmission troubles and must be removed from the system before the transmission is put back into service.

Whenever a transmission has been disassembled to replace worn or damaged parts or because the valve body sticks from foreign material, the torque converter and transmission fluid cooler must be cleaned by using a mechanically agitated cleaner, such as Rotunda Torque Converter and Oil Cooler Cleaner 014-00028 or equivalent.

PROCEDURE
Follow the instructions included with Rotunda Torque Converter/Oil Cooler 014-00028 or equivalent, flush out the torque converter.

NOTE: Mineral spirits used to clean the torque converter must be fresh, non-chlorinated and non-halogenated.

After flushing the torque converter, follow these steps:
1. Thoroughly drain the remaining solvent through the converter housing access plug.
2. Add 1.9 liter (2 qt) of clean transmission fluid to the torque converter.
3. Agitate the solution inside the torque converter by hand.
4. Thoroughly drain the solution through the impeller hub.
