Symptoms:

  • Soft shifts
  • Low line rise
  • Slips & flares

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.

As a result, critical pressure is lost due to excessive clearance between the plug and bore. Sonnax O-ringed end plug kit 97741-19K restores correct circuit pressures by positively sealing to reduce pressure losses past the end plug.
