  • 4-5 Flare
  • 5th Slip
  • Bind-up

Direct clutches in Ford 6R140 transmissions are applied in third, fifth and Reverse gears in conjunction with other clutch packs. As the direct clutch regulator valve oscillates and strokes over time, bore deterioration results, allowing critical pressure to exhaust and preventing proper hydraulic control of the direct clutch. This can cause flares, slipping, erratic clutch apply timing, ratio codes, bind-ups, and burnt direct clutches.

Reconditioning the bore and installing Sonnax oversized direct clutch regulator valve kit 126740-11K revives normal shift operation by restoring the hydraulic integrity of the direct clutch circuit.

  • Annular grooves help center valve in bore to reduce future side-load wear
  • Hardcoat anodized aluminum valve combats premature wear
