CAUTION: Whenever a transaxle 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 the Rotunda Torque Converter/Oil Cooler Cleaner 307-FOl1 (014-00028) or equivalent. Under no circumstances should an attempt be made to clean converters by hand agitation with solvent.When internal wear or damage has occurred in the transaxle, metal particles, clutch plate material, or band material may have been carried into the torque converter and fluid cooler. These contaminants are a major cause of recurring transaxle concerns and MUST be removed from the system before the transaxle is returned to service.
TRANSMISSION FLUID COOLER FLOW TEST
NOTE: The transaxle linkage should be checked for proper adjustment. The fluid level and line pressure must be within specification before performing this test.
1. Remove fluid level indicator from fluid filler tube.
2. Place a funnel in filler tube.
3. Raise vehicle on hoist and position suitable safety stands under vehicle.
4. Remove cooler return tube (lower fitting) from fitting on transaxle case.
5. Connect one end of a hose to the cooler return tube and route the other end of the hose up to a point where it can be inserted into a funnel at the fluid filler tube.
6. Remove safety stands and lower vehicle. Insert end of hose into funnel.
7. Start engine and run at idle with transaxle in NEUTRAL.
8. When fluid flowing from hose is all liquid, an adequate amount of fluid should be observed (approximately 1 liter [1 quart] delivered in 30 seconds). If adequate flow is observed, test is complete.
9. If flow is not adequate, stop engine. Disconnect hose from cooler return tube and connect it to converter-out tube (upper fitting) on case.
10. Repeat Steps 7 and 8. If flow is now approximately 1 liter (1 quart) in 30 seconds, perform Transmission Fluid Cooler-Backflushing/Cleaning. If flow is still not approximately 1 liter (1 quart) in 30 seconds, service the pump and/or converter.
