Stall Speed Test
Stall Speed Test1. Make sure the transmission fluid is filled to the proper level.
2. Apply the parking brake, and block all four wheels.
3. Connect the HDS to the DLC (A), and go to the A/T data list.
4. Make sure the HDS communicates with the PCM. If it does not, go to the DLC circuit troubleshooting.
5. Make sure the A/C switch is OFF.
6. After the engine has warmed up to normal operating temperature (the radiator fan comes on), shift to D.
7. Firmly press the brake pedal, then fully press the accelerator pedal for 6 to 8 seconds, and note the maximum engine speed. Do not move the shift lever while raising engine speed.
8. 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.
^ Stall speed tests should be the same in D and R.
^ Do not test stall speed with the A/T oil pressure gauges installed.
