Sonnax Honda Acura A4RA CPC Valve Body Spring B4RA M4RA Automatic Transmission
OPT Product Code: SNX-88894$13.85
Product Details
Common complaints in the A4RA, B4RA, and M4RA transmissions are harsh upshifts, downshifts and forward engagements, while reverse engagement is fine. These problems can be caused by a broken CPC (clutch pressure control) valve spring. The spring is located in the secondary valve body, and not available from Honda. Sonnax has developed a replacement spring 88894 that has a wire diameter larger than the OEM design. This significantly reduces the stress on the spring, preventing future breakage. This is a real valve body saver!
