Line Pressure Test: Notes
CAUTION:
Carry out Line Pressure Test prior to carrying out Stall Speed Test. If line pressure is low at stall, do not carry out Stall Speed Test or further transmission damage will occur. Do not maintain wide open throttle in any gear range for more than five seconds.
NOTE:
Certain sensor failures may cause high EPC, FMEM (Failure Mode Effect Management) actions. Be sure that self test and electrical repairs have been carried out, or test results may be incorrect.
This test verifies that the line pressure is within specifications.
- Connect pressure gauge to the line pressure tap on the transmission and a tachometer to the engine.
- Start the engine, increase and maintain 1,000 engine RPM and check line pressures. Refer to the LINE PRESSURE CHART .
