Line Pressure Check Procedure
^ Tools Required
- J 21867 Universal Pressure Gauge Set
Important: Before performing a line pressure check, verify that the pressure control (PC) solenoid valve is receiving the correct electrical signal from the PCM.
1. Install a Scan Tool.
Caution: Keep the brakes applied at all times in order to prevent unexpected vehicle motion. Personal injury may result if the vehicle moves unexpectedly.
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. Testing and Inspection
6. Check the manual linkage for proper adjustment.

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.
10. Access the PC solenoid valve control test on the Scan Tool.
11. Increase the PC solenoid 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 J21867.
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. Incorrect Line Pressure
14. Remove the J 21867.
15. Apply sealant GM P/N 12345382 to the oil pressure test hole plug
