Line Pressure Check Procedure Tools Required Important: Before performing a line pressure check, verify that the pressure control (PC) solenoid valve is receiving the correct electrical signal from the PCM. Caution: Keep the brakes applied at all times in order to prevent unexpected vehicle motion. Personal injury may result it the vehicle moves unexpectedly. J 21867Universal Pressure Gauge Set 1. Install a Scan Tool. 2. Start the engine and set the parking brake. 3. Check for a stored Diagnostic Trouble Code (DTC). 4. Repair the vehicle, if necessary. 5. Check the fluid level. Refer to the Transmission Fluid Checking Procedure. 6. Check the manual linkage for proper adjustment. 7. Turn the engine OFF. Remove the oil pressure test hole plug and install the J 21867. 8. Put the gear selector in PARK range and set the parking brake. 9. Start the engine and allow the engine to warm up at idle Notice: Total test running time should not be longer than two minutes, or else transmission damage could occur. Notice: Refer to Fastener Notice in Cautions and Notices. Parts Information 10. Access the PC solenoid valve control test on the Scan Tool. Zoom Sized for Print 11. Increase the PC solenoid as shown actual current from 0.0 to 1.0 amps in 0.1 amp increments. Allow the pressure to stabilize for five seconds after each pressure change. Read the corresponding line pressure on the J 21867. 12. Refer to the Line Pressure specification table. Compare the data to the table. 13. If pressure readings differ greatly from the table, refer to Incorrect Line Pressure. 14. Remove the J 21867. 15. Apply sealant, P/N 12345382 (in Canada, P/N 10953489), to the oil pressure test hole plug. 16. Install the oil pressure test hole plug. Tighten Tighten the oil pressure test hole plug to 12 N.m (106 lb in).
