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 15mm end plug 98892-03 replaces the worn OE end plugs and restores critical circuit pressures. The drop-in Zip Valve™ installs quickly and easily.
