Tools Required

Important: Perform this test should only at a normal operating fluid temperature of 70-80°C (158-176°F).

1. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
2. Remove the line pressure tap bolt from the transmission case.
3. Install J 35752 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 J 35752 .
5. Install J 21867 into the brass fitting.
6. Lower the vehicle.
7. Route the J 21867 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 J 21867 from the passenger compartment.
17. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
18. Remove J 21867 from the brass fitting.
19. Remove the brass fitting from J 35752 .
20. Remove J 35752 from the line pressure tap.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

21. Install the line pressure tap bolt into the line pressure tap at the rear of the transaxle.

Tighten
Tighten the line pressure tap bolt to 17 N·m (12 lb ft).

22. Lower the vehicle.

Evaluation

Compare the line pressure test results with the Line Pressure Results in the following table. If the line pressure is not as specified, refer to the Line Pressure Test Diagnosis for further evaluation.
