700R4 Valve Body, remanufactured and ready to install. Fits the 700R4. Ships fast from the USA.
If your 700R4-equipped C/K pickup, Blazer, Suburban, Camaro, Corvette or Caprice is shifting harsh, slipping between gears, flaring on a shift, or has started engaging late after you drop it into gear, the valve body is the usual culprit. This is a remanufactured, bench-ready 700R4 valve body built to GM reference 376020, the general-application revision that covers the bulk of 700R4 installs across the run, so you install a known-good unit instead of chasing worn bores and a stretched TV cable piece by piece.
The 700R4 is a hydraulically controlled, TV-cable automatic with no onboard computer, so the valve body alone decides when and how hard each shift happens. It routes line pressure through its bores and spool valves to apply the clutch packs and bands, and the throttle valve cable - not a sensor - tells it how much pressure to use based on how far your foot is into the throttle. Wear in those bores, or a cable that has drifted out of adjustment, shows up immediately as bad shift quality.
Most of these trace back to the TV cable rather than the valve body itself. Before you order, confirm the cable is adjusted correctly - our 700R4 valve body problems and testing guide walks through isolating a true valve body fault from a cable that just needs resetting, and our 700R4 common problems and fixes guide covers the 3-4 clutch and sun shell failures this unit is known for.
This valve body fits the 700R4 as installed in 1982-1992 Chevrolet C/K pickups, Blazer, Suburban, Camaro, Corvette and Caprice, and GMC pickups, and it is built to the 376020 reference used across most of that production run. The 700R4 saw several running changes over a decade of production, including dedicated early and late manual valve body revisions, so match your casting marks and connector routing against the listing photos before ordering. If you already know your exact year, check our year-specific 700R4 valve body listings or the full 700R4 parts collection, and send us your year and application if you are not sure which revision you need.
Change the fluid and filter at the same time as the valve body so debris from the old unit does not circulate into the new one, and torque the valve body bolts in sequence to spec rather than corner to corner. Because this is a TV-cable transmission with no adaptive relearn, the cable adjustment you set after installation is what determines shift quality going forward - do it by the book rather than by feel. If your old cable is stretched, frayed, or was the root cause of your failure, replace it with a fresh TV kickdown cable kit rather than reusing a worn one, and consider a reaction (sun) shell at the same time if your old one shows the scoring that chronic low line pressure causes. Adding a dedicated transmission cooler is cheap insurance against the heat that shortens this valve body's life a second time.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is built to the 376020 reference used across most of the 1982-1992 production run, but the 700R4 went through several revisions. Match the casting marks and connector routing against the listing photos, or send us your year and vehicle so we can confirm, before ordering.
Harsh, late or flared shifts, slipping between gears, delayed engagement, and a burnt 3-4 clutch or sun shell all point to the valve body or chronic low line pressure - but check your TV cable adjustment first, since that alone causes most of these symptoms.
1982-1992 Chevrolet C/K pickups, Blazer, Suburban, Camaro, Corvette and Caprice, and GMC pickups.
Dexron ATF. A current Dexron-VI fill is backward compatible with the Dexron, Dexron-II and Dexron-III fluids this transmission originally called for.
Yes - adjust the TV cable correctly. The 700R4 has no computer and no adaptive relearn, so the cable adjustment you set after the swap is what determines shift quality from then on.
Fluid and filter at minimum. If your old TV cable is worn or was the cause of your failure, replace it too, and inspect the reaction (sun) shell for scoring if your symptoms included a burnt 3-4 clutch.
