Stall Speed Test

  1. Make sure the transmission fluid is filled to the proper level (see ATF LEVEL CHECK  ).
  2. Apply the parking brake, and block the front wheels.
  3. Connect the HDS to the DLC, and start the engine.
  4. Make sure the A/C switch is OFF.
  5. After the engine has warmed up to normal operating temperature (the radiator fan comes on), shift to the D position.
  6. Firmly press the brake pedal and accelerator pedal for 6 to 8 seconds, and note engine speed. Do not move the shift lever while raising engine speed.
  7. Allow 2 minutes for cooling, then repeat the test in the R position.
    NOTE:
    • Do not test stall speed for more than 10 seconds at a time.
    • Stall speed tests should be used for diagnostic purposes only.
    • Stall speed should be the same in the D and R positions.
    • Do not do the stall speed test with the A/T pressure gauges installed.
