Stall Speed Test
- Make sure the transmission fluid is filled to the proper level (see ATF LEVEL CHECK ).
- Apply the parking brake, and block all four wheels.
- Connect the HDS to the DLC (A), and go to the A/T data list. If the HDS does not communicate with the PCM, troubleshoot the DLC circuit (see DLC CIRCUIT TROUBLESHOOTING ).
- Make sure the A/C switch is OFF.
- After the engine has warmed up to normal operating temperature (the radiator fan comes on), shift to D.
- Firmly press and hold the brake pedal then, while still holding the brake pedal, press the accelerator pedal for six to eight seconds, and note maximum engine speed. Do not move the shift lever while raising engine speed.
- Allow 2 minutes for cooling, repeat the test for the seven-position transmission in 2, and allow 2 minutes, then repeat test in 1.
- Allow 2 minutes for cooling, then repeat the test in R.NOTE:
- Do not test stall speed for more than 10 seconds at a time.
- Stall speed tests should be used for diagnostic purposes only.
- The stall speed should be the same in D, 2, 1, and R.
- Do not test stall speed with the A/T pressure gauges installed.
