Fluid Pump: Testing and Inspection
31TH
31TH - AUTOMATIC TRANSMISSION
STANDARD PROCEDURE - OIL PUMP VOLUME CHECK
Measuring the oil pump output volume will determine if sufficient oil flow to the transmission oil cooler exists, and whether or not an internal
transmission failure is present.
Verify that the transmission fluid is at the proper level. If necessary, fill the transmission to the proper level with Mopar ATF +4, type 9602, Automatic
Transmission Fluid.
1. Using hose cutters or a suitable blade, cut the To cooler line off flush with the cooler inlet fitting and place a collecting container under the open
line.
CAUTION: With the fluid set at the proper level, fluid collection should not exceed 1 quart or internal damage to the transmission may occur.
2. Run the engine at curb idle speed, with the shift selector in neutral.
3. If one quart of transmission fluid is collected in the container in 20 seconds or less, oil pump flow volume is within acceptable limits. If fluid flow
is intermittent, or it takes more than 20 seconds to collect one quart of fluid, Refer to further diagnosis.
4. Re-connect the To cooler line to the transmission cooler inlet using a service splice kit. Refer to instructions included with the kit.
5. Refill the transmission to proper level.
