Stall Speed Test Procedure
WARNING: This page is about a different car, the 2003 Toyota RAV4, 2002 Toyota RAV4, 2002 Toyota Highlander, 2001 Toyota RAV4, and 2001 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Perform test at normal operating fluid temperature of 122-176°F (50-80°C). DO NOT continue test for more than 10 seconds.
- Testing is done to check overall performance of transaxle and engine by measuring maximum engine speeds in "D" and "R" positions.
- Block front and rear wheels. Connect scan tool to Data Link Connector (DLC3) to monitor engine RPM. Apply parking and service brakes. Start engine. Place gearshift lever into "D" position. Fully depress accelerator pedal. Release pedal after 10 seconds.
- Record highest engine RPM. Repeat test in "R" position. Compare reading obtained to specification. Stall speed should be 2200-2550 in both "D" and "R" positions.
- If stall speed is same for both positions, but lower than specified RPM, engine output may be insufficient or stator one-way clutch is not operating properly.NOTE: If stall speed RPM is more than 600 RPM less than specification, torque converter may be faulty.
- If stall speed in "D" position is higher than specification, forward clutch may be slipping, No. 2 one-way clutch may not be operating properly, underdrive clutch may be slipping, or line pressure is too low.
- If stall speed in "R" position is higher than specification, direct clutch may be slipping, 1st/reverse brake may be slipping, line pressure is too low or underdrive clutch may be slipping.
- If stall speed in "R" and "D" positions is higher than specification, line pressure is too low, incorrect fluid level exists or No. 2 one-way clutch is not operating properly.
