Line Pressure Test

  1. Perform line pressure test after A/T has reached operating temperature of 176°F (80°C). Ensure fluid level and condition have been checked and are acceptable.
  2. Measure line pressure with gear selector in "N" and engine idling. Measure kickdown line pressure with throttle valve cable withdrawn fully and engine speed at 2000 RPM.
  3. Connect oil pressure gauge to pressure port in A/T housing. See Fig 1 . Start engine, obtain pressure readings and refer to specifications. See appropriate LINE PRESSURE SPECIFICATIONS  table.
