Line Pressure Test

NOTE:
- This test verifies that the line pressure is within specifications.
- Refer to Powertrain Management and check engine idle speed.

CAUTION:
- Perform line pressure test prior to performing stall speed test. If line pressure is low at stall, do not perform stall speed test or further transaxle damage will occur. DO NOT MAINTAIN WOT in any gear range FOR MORE THAN FIVE (5) SECONDS.
- Transmission tester MUST BE REMOVED from the transaxle and the vehicle harness connected to VERIFY these pressures.





PROCEDURE
1. Connect pressure gauge to line pressure tap.





2. Start engine and check line pressures. Refer to the chart to determine if line pressure is within specification





3. If line pressure is not within specifications, perform on-board diagnostics and pinpoint test air pressure check and service main control system or pump as required.
