Transmission Cooler: Testing and Inspection
NOTE: The linkage, fluid and control pressure must be within specification before performing this flow check.
1. Remove transmission dipstick from filler tube, then place funnel in filler tube.
2. Raise and support vehicle, then remove cooler return line from its fitting in case.
3. Attach hose to cooler return line and fasten free end of hose to funnel installed in filler tube.
4. Start engine and set idle speed at 1000 RPM with transmission in NEUTRAL.
5. Observe fluid flow at funnel. When flow is solid, air bleeding has been completed, flow should be liberal. If there is not a liberal flow at 1000
RPM in NEUTRAL, low pump capacity, main circuit system leakage, or cooler system restriction is indicated.
6. To separate transmission trouble from cooler system trouble, observe flow at transmission case converter out fitting.
