C6 Reverse Shift Pattern Full Manual Valve Body 1966-1996 OEM 421000

The C6 Reverse Shift Pattern Full Manual Valve Body 1966-1996 OEM 421000 is a direct-fit replacement valve body for the C6, covering 1966-1996 applications.

The valve body is the hydraulic control center of the C6 - it meters line pressure and routes it to the clutches and bands to time every shift. When the bores wear, you get harsh or soft shifts, slipping, delayed engagement and shift-quality codes.

This unit is remanufactured and tested with the correct updates before it ships, so you install a verified valve body instead of reusing a worn core.

Ships fast from the USA and is ready to bolt in. If you are unsure which C6 valve body fits your year and application, check the fitment before ordering or reach out and we will confirm the right unit.
