Line Pressure Check Procedure
Line Pressure Test Diagnosis
^ Tools Required
- J35752 Oil Adapter Gauge Adapter
- J21867 Pressure Gauge
Important: Perform this test only at a normal operating fluid temperature of 70 - 80°C (158 - 176°F).
1. Raise and suitably support the vehicle. Refer to Vehicle Lifting.
2. Remove the line pressure tap bolt from the transmission case.
3. Install J35752 into the line pressure tap.
4. Install a 90 degree male elbow inverted flare brass fitting with a 3/16 inch tube OD and a 1/8 inch male pipe thread into J35752.
5. Install J21867 into the brass fitting.
6. Lower the vehicle.
7. Route the J21867 hose over the front fender and through the driver's window so that you can read the hose from the passenger compartment.
8. Apply the parking brake and block the vehicle wheels.
9. Press the brake pedal fully and start the engine.
Caution: For the following four steps, procedures for testing line pressure at Idle and stall speeds, the brake pedal must be fully pressed throughout the measurement procedure. Failure to do so could result in personal injury and/or property damage.
10. Place the manual selector to Reverse (R) and record the line pressure at idle speed (750-850 RPM).
Notice: DO NOT run engine at stall speed for more than five seconds continuously or engine oil and transaxle fluid temperatures may become excessively high.
11. With the manual selector still in Reverse (R), press the accelerator pedal fully (wide open throttle) and record the line pressure.
12. Release the accelerator pedal and let the engine return to idle speed.
13. Move the manual selector to Drive (D) and record the line pressure at idle speed (750-850 RPM).
14. With the manual selector still in Drive (D), press the accelerator pedal fully (wide open throttle) and record the line pressure.
15. Place the selector lever in the Park (P) position and turn the ignition switch to LOCK.
16. Remove J21867 from the passenger compartment.
17. Raise and suitably support the vehicle. Refer to Vehicle Lifting.
18. Remove J21867 from the brass fitting.
19. Remove the brass fitting from J35752.
20. Remove J35752 from the line pressure tap.
Notice: Refer to Fastener Notice in Service Precautions.
21. Install the line pressure tap bolt into the line pressure tap at the rear of the transaxle.
^ Tighten the line pressure tap bolt to 17 Nm (12 ft. lbs.).
22. Lower the vehicle.
Evaluation
