Stall Speed Test
Stall Speed Test1. Make sure the transmission fluid is filled to the upper 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.

7. Firmly press the brake pedal and the accelerator pedal for 6 to 8 seconds, and note the engine speed. Do not move the shift lever while raising the 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.
^ Record the engine speed at 6 - 8 seconds after pressing the accelerator pedal. Higher engine speed will be indicated for 5 seconds.
^ Stall speed tests should be used for diagnostic purposes only.
^ Stall speed should be the same in D and R.
^ Do not test stall speed with the A/T oil pressure gauges installed.
