Transmission Toyota/Lexus U250E U151F U151E Valve Body Valve / Sleeve

Symptoms:

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

Cause:

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.

Correction:

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