Symptoms:

  • Inconsistent shift quality

Cause:

Valves, springs and pressurized fluid repeatedly push on the end plugs causing the plugs to deform and wear. As a result, critical pressure is lost due to excessive clearance between the plug and bore.

Correction:

The Sonnax O-ringed end plugs restore correct circuit pressures. The O-ring provides additional sealing to reduce pressure losses past the end plug

View Instructions Find a Distributor

Valves, springs and pressurized fluid repeatedly push on end plugs causing them to deform and wear. As a result critical pressure is lost due to excessive clearance between the plug and bore. The Sonnax double O-ring sealed end plug kit for ZF6HP19/26/32 (Gen. 1) and Ford 6R60, 6R80 units replace the damaged OE end plugs and restore pressure containment to the valve bore. Sonnax internal end plug kit 95740-25K services the four individual bores in the valve body which use internal end plugs to isolate valves from solenoids.

  • Prevent loss of critical pressure
  • Requires no machining or special tools
  • Services all four bores to isolate valves from solenoids with 12mm internal end plugs
