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.
This valve will not fit early-style "clicker" or Shelby valve bodies with screw on end plate behind boost valve.
