Product Description
01J Oversized VSTV Pilot Pressure Valve
Sonnax Part Number: 33741B-06
TOOLING REQUIRED
- F-33741B-TL6
- VB-FIX
In VW/Audi 01J transmissions, the VSTV valve is the regulator to both N88 shift pressure and the N215 line pressure control solenoids. As the bore wears, solenoid output will not react according to the control module requirements, eventually setting adaption limit codes. Sonnax oversized VSTV pilot pressure valve 33741B-06 allows the bore to be refurbished and restores the hydraulic integrity of the circuit for proper modulated VSTV pilot pressure. Hardcoat anodized aluminum valve combats premature wear
PACKAGE CONTAINS
- Valve
SYMPTOMS
- Delayed engagement

- Unstable solenoid pressure
CAUSE
Bore wear at the VSTV valve allows pressure escape that causes drivability issues.
CORRECTION
Reconditioning the bore and installing the Sonnax VSTV pilot pressure valve re-establishes proper modulated VSTV pilot pressure.
