  • Various concerns depending on location of leaking end plug
  • Low CPC Pressure
  • Soft & inconsistent shift feel


Worn, eroded end plugs allow loss of critical hydraulic pressure.


Sonnax O-ringed end plug restores correct circuit pressures. The O-ring provides additional sealing to prevent hydraulic loss.


Some BMXA units have been found with plugs which have smaller diameter clip-grooves and narrower retainers as shown here. Sonnax end plugs will not work in these applications.

Valve bore plugs on Honda/Acura 4-speed, 3-shaft, and 5-speed valve bodies wear and allow critical CPC and solenoid feed oil to leak to exhaust, leading to low CPC pressures and soft or inconsistent shifts. Sonnax 14mm O-ringed end plug 98892-02 replaces the worn OE end plugs and restores critical circuit pressures.

Due to application variations, additional end plugs may be required. Single end plugs in all three sizes (12mm, 14mm, 15mm) are available separately or as part of a kit. See related parts below.
