- Increase Engine Speed (RPM) briefly (max. 5 seconds), if necessary, repeat test after 20 secs. When doing this the stall speed listed in the table must be attained.
- If the final specified stall speed is not attained, the following malfunctions are probable causes:
Symptom Probable Cause
Stall speed too high: Forward clutch slipping, free-wheel slipping
Stall speed up to 200 RPM too low: Check engine settings
Stall speed more than 200RPM too low: Torque converter malfunctioning
In cases of doubt, the engine settings must always be checked first and, if necessary, corrected.
The transmission must always have the correct torque converter installed.
