• Clutch & band failures
• Harsh shifts
• High line pressure
• High pressure in Reverse
• Low converter pressure
• Low line pressure
• Soft shifts

Continuous oscillation of the pressure regulator valve causes valve body bore wear, which results in line pressure irregularities and valve instability. Severe wear of the boost valve sleeve allows EPC and reverse oil leakage.

This oversized pressure regulator valve and boost assembly allows the valve body bore to be restored to normal operating condition.
