Description
Symptoms:
- Low line pressure
- Delayed Drive
- Delayed Reverse
Cause:
The worn manual valve bore or spools allows function-critical hydraulic pressure to escape directly to sump and / or adjacent circuits, exhibiting low line pressure and related engagement delays.
Correction:
Restore critical hydraulic control by refurbishing the worn bore with the Sonnax tool kit and installing the oversize Sonnax manual valve.
