Transmission Fluid Cooler Flow Test
NOTE:
- The transmission linkage/cable adjustment, fluid level and line pressure must be within specification before performing this test; see SHIFT CABLE AND BRACKET ADJUSTMENT or see TECHNICAL DATA for adjustments.
- Remove fluid level indicator from fluid filler tube.
- Place funnel in fluid filler tube.
- Raise the vehicle on a hoist and place suitable safety stands under the vehicle.
- Remove the cooler return line (rear fitting) from the fitting on the transmission case.
- Connect one end of a hose to the cooler return line and route other end of the hose up to a point where it can be inserted into the funnel at the fluid filler tube.
- Remove the safety stands and lower the vehicle. Insert end of hose into the funnel.
- Start the engine and run it at idle with the transmission in NEUTRAL position.
- When fluid flowing from hose is in a steady stream, a liberal amount of fluid should be observed. "Liberal" is described as about 1 liter (1 qt) delivered in 30 seconds. If a liberal flow is observed, the test is complete.
- If the flow is not liberal, stop the engine. Disconnect the hose from the cooler return line and connect it to the converter outlet fitting (front fitting) on the transmission case.
- Repeat Steps 7
and 8
.
- If flow is now approximately 1 liter (1 quart) in 30 seconds, see AUTOMATIC TRANSMISSION POWER FLUSHING .
- If the flow is still not approximately 1 liter (1 quart) in 30 seconds, service the pump and/or torque converter.
