Product Description
01M 01N 01P Oversized Main Pressure Regulator Valve Kit
No tooling required
In VW/Audi 01M, 01N and 01P transmissions, regulated line leaks to exhaust at the pressure regulator creates a low pressure condition. Wear at the inner balance spools prevent the valves from stroking, which can cause high line pressure. Wear at the inboard bore also affects the K1 clutch circuit, which can result in 1-2 or 2-3 shift complaints. Reconditioning the bore and installing Sonnax oversized main pressure regulator valve kit 119940-03K restores hydraulic integrity.
- Hardcoat anodized aluminum valve combats premature wear
- Contains an O-ringed end plug to positively seal the bore and prevent regulated boost line pressure from exhausting
- A new spring is included to work with the oversized valve and re-establish OE regulated pressure specifications
Symptoms
- Delayed engagement
- Engine stall at idle
- High line pressure in Reverse
- Erratic line pressure
- No line rise
Cause
Wear at the large end of the main regulator valve can cause low line pressure. Wear at the inboard end of the main regulator valve causes high line pressure.
Correction
Recondition the bore and install Sonnax oversized main pressure regulator valve kit with improved boost oil circuit and converter feed.
