Line Pressure Tests: Notes

CAUTION: Parking brake must be applied during test. Ensure test DOES NOT  exceed 2 minutes.
  1. Check ATF level, Throttle Valve (T.V.) cable adjustment and manual control linkages. See appropriate AUTOMATIC TRANSMISSION SERVICING article in TRANSMISSION SERVICING. Ensure engine is tuned properly.
  2. Connect tachometer to engine. Connect pressure gauge to pressure test port on transaxle case. Pressure test port is on bellhousing side, above valve body cover.
  3. Line pressure is controlled by pump output and pressure regulator valve. Line pressure is boosted by reverse boost valve in "R", "2" and "1" positions. Line pressure should increase with throttle opening in "N", "D" and "R" positions.
