Hydraulic Test

1. Road test vehicle until transaxle reaches normal operating temperatures (122-176 degrees F).
2. Block rear wheels, then raise and support front of vehicle.
3. Remove transaxle case test plugs, then connect hydraulic pressure gauges to adapter tool No. J-35752.
4. Lower vehicle. Measurement can be made with 800 or 1000 RPM test, but if tests are to be made at 1600-1800 or 2400-3500 RPM, perform test on road or dynamometer.
5. Ensure parking brake is applied, then start and idle engine.
6. Shift selector lever into "D," then measure governor pressure at specified speeds in chart.
7. If governor pressure is not within specifications, incorrect line pressure, leaking governor pressure circuit or improper governor valve operation is indicated.
8. Fully apply parking brake, then block all four wheels.
9. Start and idle engine, then shift selector lever into "D" range.
10. With brake pedal firmly applied, accelerate engine until speeds specified in are obtained, then measure line pressures.
11. Repeat test with selector lever in "R."
12. If measured pressures are not as specified in chart, adjust throttle cable, then repeat test
13. If measured values in all ranges are higher than specified, misadjusted throttle cable, defective throttle valve or defective regulator valve is indicated.
14. If measured values are lower than specified in all ranges, a misadjusted throttle cable, defective throttle valve, defective regulator valve or defective oil pump is indicated.
15. If pressure is low in "D" range only, a leaking "D" range circuit or defective forward clutch is indicated.
16. If pressure is low in "R" range, a leaking "R" range circuit, defective direct clutch or defective first and reverse brake is indicated.
