- 2-3 Flare
- Delayed engagement
- Erratic line pressure
- PR valve buzz
- Reverse chatter
- Reverse slip
Continuous oscillation of the steel valve wears the cast aluminum bore, allowing valuable oil to leak.
This oversized valve permits the valve body to be restored to OE specifications.
Oversized Pressure Regulator Valve
Bore wear at the inside spool in Ford C6 units causes imbalance or a buzz condition along with high line pressure at operating temperatures. High line pressure causes harsh engagements and reduced converter fill. The valve bore also wears near the socond spool. This wear reduces line pressure and causes delayed engagement or soft/flare upshift concerns. Sonnax oversized pressure regulator valve 36946-10K corrects these conditions.
- Replacement valve is made of aluminum instead of the OE steel, which reduces thermal expansion clearances
- Valve is hardcoat anodized to reduce wear
- Valve incorperates annular grooves to help the valve ride on a film of oil to reduce wear
Required tool kit 36946-TL is no longer in production. Check with your distributor for availability.
This valve will not fit early-style "clicker" or Shelby valve bodies with screw on end plate behind boost valve.
