Stall Test Results
- If transaxle operation is okay at freeway speeds, but vehicle has poor acceleration, stator overrunning clutch may be slipping. Stall speed should be 1950-2050. Transaxle over-heating and poor fuel economy may also result.
- If vehicle acceleration is okay, but additional throttle is needed to maintain freeway speeds (lack or power), stator overrunning clutch may be seized. Transaxle over-heating and poor fuel economy may also result.
- If stall speed is greater than 2640 RPM, a clutch is slipping. Diagnose clutch circuits by performing hydraulic and air pressure tests. Transaxle clutches may also be checked using scan tool. Input and output sensor speeds can be compared while controlling clutch operation with scan tool. See SCAN TOOL INSTRUCTIONS.
