Cause:
Pressure regulator and plunger valves and bores show significant wear.
Correction:
Sonnax oversized pressure regulator valve kit restores OE normal line pressure and shift concerns.
Excessive Renault/Peugot AL-4 and DPO plunger valve and bore wear results in high line pressure conditions. Excessive wear of the pressure regulator valve and bore in these units may cause low, high or unstable line pressure issues. Reconditioning the bore and installing the Sonnax oversized pressure regulator valve kit restores correct pressure regulator and plunger valve operation to provide appropriate line pressure for all operating conditions.
