Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Stall Speed Test: Notes
- Perform the line pressure test at engine idling prior to performing the test at engine stall. If line pressure is low at idle do not perform the test at engine stall or further transaxle damage will occur.
- Perform mechanical system test preparation. (See MECHANICAL SYSTEM TEST PREPARATION .)
- Connect a tachometer.
- Start the engine.
- Shift the selector lever to D range.CAUTION:
- Do not maintain WOT in any gear range for more than 5 seconds or transaxle damage will occur.
- If engine sped recorded by the tachometer exceeds maximum specified RPM, release the accelerator pedal immediately. Clutch or band slippage is indicator.
- Firmly depress the brake pedal with the left foot, and gently depress the accelerator pedal to the floor (WOT) with the right.
- When the engine speed no longer increases, quickly read the engine speed and release the accelerator pedal.
- Shift the selector the to N position and let the engine idle for 1 minute or more to cool the ATF.
- Perform stall tests for the remaining ranges and position in the same manner.
- R position
- 3 range
- 2 range
