700R4 Valve Body 1982, new and ready to install. Fits the 700R4. Ships fast from the USA.
1982 was the first model year for the 700R4, and GM's first attempt at the throttle valve (TV) cable system that controls line pressure on this transmission had the least amount of real-world durability data behind it of any year in the production run. If your 1982 Chevrolet or GMC truck, Blazer, Suburban, Camaro, Corvette or Caprice is shifting harsh, slipping, or hanging in neutral before it engages, a new TransGo valve body is a direct path back to correct shifts without gambling on a decades-old used casting.
The valve body is the hydraulic brain of the transmission. Pump pressure arrives at the valve body and is routed through a set of precision bores and spool valves that apply each clutch pack and band in the right sequence for the gear you're asking for. On the TV-cable 700R4, the valve body also carries the throttle valve plunger, which translates cable tension into the line pressure rise that keeps clutches from slipping under load - this is the specific piece TransGo is best known for addressing on this transmission family.
Check the TV cable adjustment first, since a cable that has crept out of spec produces the same harsh-shift and slip symptoms as a worn valve body and costs nothing to rule out. Our 700R4 valve body testing guide covers the line pressure and stall-speed checks that tell you whether the problem is the cable, the valve body, or something further downstream in the transmission.
This valve body fits the 700R4 as installed in 1982 Chevrolet C/K pickups, Blazer, Suburban, Camaro, Corvette and Caprice, and the equivalent GMC trucks. As the first production year, 1982 units can carry early-run castings that were revised later, so match your old unit's casting and TV plunger bore configuration before installing, or confirm your VIN with us if you're not certain. See the full 700R4 parts collection for everything else we stock for this transmission.
Drop the pan and change the fluid and filter at the same time as this valve body swap so contamination from the old unit isn't recirculated through the new one. Torque the valve body bolts in sequence to spec, reinstall and readjust the TV cable per spec, and refill with Dexron ATF. Road test through every gear, including a full-throttle downshift check, before calling the job finished. If the sun shell or pump bushings on your 1982 unit are also showing age, pair this with a 700R4 sun shell or a 700R4 shift kit rather than replacing the valve body alone.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
A new unit removes the uncertainty of an unknown wear history on a casting that's over 40 years old, and TransGo is specifically known for addressing the TV-cable line pressure issues that define this early 700R4 generation.
Yes - reinstall and adjust the throttle valve cable to spec after the swap so the valve body's TV plunger receives the correct pressure signal.
Dexron ATF. Change the fluid and filter at the same time you install this valve body.
It can be, but early 700R4 units also fail at the sun shell and pump or stator bushings. Check line pressure and the TV cable adjustment first to confirm the valve body is the actual cause before ordering.
It's built for the 1982 configuration specifically. If your vehicle is a 1983-86 model, check our 700R4 valve body 1982-86 listing, since casting revisions across these years mean matching the exact configuration matters for a clean fit.
