Check stall speed in conjunction with a system pressure check.
The check primarily provides information on the condition of the torque converter, transmission clutches and the engine.
The following is necessary to ensure correct test results:
- The engine provides full output
- System pressure is correct
- the transmission has the correct oil level and operating temperature
NOTE:
Never check stall speed if system pressure is low
