Stall Speed Test

Engage the parking brake, and block the front wheels.
Connect a tachometer to the engine, and start the engine.
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 the [2 ] position.
Fully press the brake pedal, accelerate for 6 to 8 seconds, and note the engine speed. Do not move the shift lever while raising engine speed.
Allow two minutes for cooling, then repeat the test in the [D ₅ ], [1 ], and [R ] positions.
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 ₅ ], [2 ], [1 ], and [R ] positions.
- Do not test stall speed with the A/T pressure gauges installed.
