Transmission Cooler: Testing and Inspection
OIL COOLER FLOW CHECK
After the new or repaired transmission has been installed, fill to the proper level with DIAMOND ATF SP-II or equivalent automatic transmission
fluid. The flow should be checked using the following procedure:
CAUTION: With the fluid set at the proper level, fluid collection should not exceed 1 quart or internal damage to the transmission may occur.
1. Disconnect the OUTLET (From) cooler line at the transmission and place a collecting container under the disconnected line.
2. Run the engine at curb idle speed, with the shift selector in neutral.
3. If fluid flow is intermittent or it takes more than 20 seconds to collect one quart of ATF, replace the cooler.
4. If flow is found to be within acceptable limits, reconnect the cooler line. Then fill transmission to the proper level, using the approved type of
automatic transmission fluid.
