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:

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