700R4 Overhaul Kit, new and ready to install. Fits the 700R4. Ships fast from the USA.
Searching for a reseal kit because your 700R4 drips from the pan rail, weeps at the front pump, or takes a second or two to grab Drive on a cold morning? This is the plain gasket and seal set for that job: the paper and rubber parts for the GM 700R4 in 1982-1993 Chevrolet and GMC pickups, Blazers, Suburbans, Camaros, Corvettes and Caprices. It is the kit a builder buys when the clutches are still good, or the base set to pair with separately chosen frictions and steels.
The kit carries part number KP33900A and is made by Precision International or Toledo Trans-Kit depending on stock; both build it to the same 700R4 application. It does not include bushings, thrust washers, frictions, steels, the band or a filter. If you want bushings and washers in the same box, see our 700R4 overhaul kit with bushings and washers.
Every shift in a 700R4 is hydraulic. The pump makes line pressure, the TV cable tells the valve body how hard to push, and that oil applies the forward, 3-4, reverse input, overrun and low-reverse clutches plus the 2-4 band. The oil only does its job if it stays in its circuit. Sealing rings carry it across the rotating shafts into the drums, lip seals on each piston turn it into clamping force, and the valve body gaskets keep one circuit from bleeding into the next. After years of heat these parts shrink and harden. A clutch fed through a leaking seal applies soft and slips, and slip is what turns a leak into a burned pack.
Rule out the easy causes first: check the fluid level hot and set the TV cable, since a misadjusted cable drops line pressure and burns the 3-4 clutch regardless of seal condition. A pressure test that reads low in one range points to a leak in that circuit. Delayed engagement can also come from the pump itself, so read our 700R4 pump failure guide before you commit, and the 700R4 common problems guide for the TV cable procedure. If the pan holds friction material or metal, the job is bigger than a reseal.
This kit is built for the cable-controlled GM 700R4, called the 4L60 from 1991, covering 1982 through 1993. It is not for the electronic 4L60E. Because many of these transmissions have been swapped between vehicles, match the new valve body gasket and pan gasket to your old ones before you start, or send us the year and VIN and we will confirm it. Other parts for this unit are on our 700R4 parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is the gasket and seal set: gaskets, sealing rings, lip seals, O-rings and the cork pan gasket. Bushings, thrust washers, frictions, steels, the band and the filter are separate.
No. It is for the cable-controlled 700R4, which GM renamed 4L60 in 1991. The electronic 4L60E uses a different kit.
Either one, depending on stock. Both build the KP33900A kit for the same 1982-1993 700R4 application.
It fixes delayed engagement caused by hardened piston seals and worn sealing rings. Low fluid, a misadjusted TV cable or a worn pump cause the same symptom, so check those first.
Dexron ATF. A current Dexron-VI fluid is backward compatible with the original Dexron grades.
