Stall speed and system pressure
WARNING: This page is about a different car, the 2004 Volvo S40, 2003 Volvo S40, 2002 Volvo S40, 2001 Volvo S40, and 2000 Volvo S40. However, it is still accessible from the selected car via links, so may be relevant.
Check stall speed in conjunction with a system pressure check.
The stall speed 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 fluid level and operating temperature.
NOTE:
Never check stall speed if system pressure is low.
