700R4 Overhaul Kit 1983-93, new and ready to install. Fits the 700R4. Ships fast from the USA.
If your 1983-1993 700R4 is leaking at the pan, the front seal or the tailshaft, or it has started to engage slowly in Drive and Reverse once it warms up, the seals inside have hardened and the bushings are letting oil escape. This overhaul kit is the paper, rubber and hard-wearing small-parts side of a rebuild for the 700R4 (called the 4L60 from 1991) in Chevrolet and GMC C/K pickups, Blazers, Suburbans, Camaros, Corvettes and Caprices. Unlike a basic gasket set, it also includes the bushing kit and the thrust washer kit, so the parts that wear against each other get renewed at the same time as the seals.
The kit is new and unbranded. Frictions, steels, the 2-4 band and the filter are not included.
The 700R4 is a hydraulically controlled 4-speed: line pressure set by the pump and the TV cable applies five clutch packs and the 2-4 band, and every one of those circuits relies on a seal or sealing ring to hold that pressure. When a piston seal hardens or a ring wears, the clutch it feeds applies late and soft, and that slip is what burns frictions. The bushings matter as much as the seals here. Worn pump and stator bushings are one of this transmission's known failures, and a loose bushing lets oil bleed off between the pump, the stator shaft and the input drum, starving the 3-4 clutch and the converter. The thrust washers set the end play of the rotating parts; replacing them keeps the drums and shells from wearing into each other after the rebuild.
Set the TV cable first. A misadjusted cable drops line pressure and is the most common reason a 700R4 burns its 3-4 clutch, and no new seal will fix that. Then pull the pan and look at what is in it. If you find only fine gray sludge and the unit still pulls in every gear, a reseal with this kit may be the right job. Friction material or heavy metal means you also need clutches and probably hard parts. Our 700R4 delayed engagement guide covers the pump and seal causes of slow engagement, and the 700R4 common problems guide walks through the TV cable check.
This kit is listed for 700R4 transmissions from 1983 through 1993. These units have often been swapped between trucks and cars over the years, so the vehicle year is a guide rather than proof. Before installing, lay the new valve body gasket and the bushings beside the old ones and confirm they match. It does not fit the electronic 4L60E. If you are not sure what is in your vehicle, send us the year and VIN and we will check it. You can see every part we carry for this unit on the 700R4 parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It covers gaskets, seals and rubber parts plus a bushing kit and a thrust washer kit. Frictions, steels, the 2-4 band and the filter are bought separately, or you can step up to a master rebuild kit.
The 4L60 is the same cable-controlled unit as the 700R4 under its later name, and this kit is listed through 1993. It does not fit the electronic 4L60E. Compare the valve body gasket and bushings with your old parts, or send us your year and VIN to check.
Only if the clutches are still good and the slip comes from pressure loss. Adjust the TV cable first, then check the pan. If the 3-4 pack is already burned you need new frictions as well as the seals.
The 700R4 was filled with Dexron ATF. A current Dexron-VI fluid is backward compatible with the older Dexron grades and is the normal choice today.
Worn pump and stator bushings let oil leak between rotating parts and starve the 3-4 clutch and converter. Replacing them along with the thrust washers restores the oil feed and end play that new seals depend on.
