Initial Inspection and Diagnostic Overview

NOTE: The torque converter is welded together and cannot be disassembled.

1. Check the torque converter for damage or cracks and replace, if necessary.
2. Inspect for damage, breakage or rough areas on the inside bushing. Make sure the bushing size is within specification. If the bushing is not within specification, replace the torque converter.
3. Remove any rust from the pilot hub and boss of the torque converter.
4. Measure the inner diameter of the boss bushing. If it exceeds 53.075 mm (2.0896 inches), replace the torque converter.
5. Inspect for contamination. When internal wear or damage has occurred in the transaxle, contaminants such as metal particles clutch plate material, or band material may have been carried into the torque converter and oil cooler. These contaminants can be a major cause of recurring transaxle troubles and must be removed from the system before the transaxle is put back into service.
^ Whenever the transaxle has been disassembled to replace worn or damaged parts or because the main control valve body sticks due to foreign material, the torque converter, oil cooler and fluid cooler tubes must be cleaned and flushed using the Rotunda Torque Converter Cleaner 014-00028 or equivalent. Under no circumstances should an attempt be made to clean the torque converter by hand.
^ The lack of a drain-plug in the torque converter increases the amount of residual flushing solvent retained in the torque converter after cleaning. This retained solvent is not acceptable, and diluting is required. The following procedure is to be used after removal of the torque converter from the cleaning equipment.
^ Thoroughly drain the remaining solvent through the torque converter hub.
^ Add 0.5L (0.53 US quarts) of specified clean transmission fluid into the torque converter. Agitate by hand.
^ Thoroughly drain the solution through the torque converter hub.
