  1. Measure the line pressure.

Notice

:

  1. Warm up the atf.
  2.  Remove the test plug on the transaxle case front left side and connect sst.

    Sst 0999200095 (0999200231, 0999200271)

  5.  Start the engine and check the idling speed.
  6.  Keep your left foot pressed firmly on the brake pedal and shift into the d position.
  7.  Measure the line pressure when the engine is idling.
  8.  Depress the accelerator pedal all the way down.

    Quickly read the highest line pressure when the engine speed reaches the stall speed.

  9. Do the test in the r position in the same way.
