700R4 Master Rebuild Kit 1987-1993, new and ready to install. Fits the 700R4. Ships fast from the USA.
A 1987-1993 700R4 that slips on the 3-4 shift, flares into 2nd, or leaves black, burnt-smelling fluid on the dipstick is past the point where a single part fixes it. This master deluxe rebuild kit is built for that job on the later 700R4 (renamed 4L60 in 1991) behind Chevrolet and GMC C/K pickups, Blazers, Suburbans, Camaros, Corvettes and Caprices. It puts every seal, every clutch pack, the band, the filter and the main bushings in one box, plus two upgrade parts the factory unit never had.
Everything in the kit is new. Packaging and brand on the frictions can vary by batch.
The 700R4 has five clutch packs, a sprag and roller clutch, and one 2-4 band. A soft-parts overhaul kit only reseals it. A master kit also renews every friction and steel and the band, which is what a high-mileage or burnt unit actually needs. The Corvette servo has a larger apply area than the stock truck servo, so it holds the 2-4 band harder and firms up the 1-2 shift. That band wears faster with a weak stock servo, and a glazed band causes a soft or flaring 2nd gear. The bushings matter too: worn pump and stator bushings are one of this unit's known failures, and they bleed off oil that the converter clutch and the 3-4 clutch depend on.
Pull the pan first. Clutch material, bronze bushing flakes or fine metal mean the unit needs to come apart. Then check the TV cable: a misadjusted cable drops line pressure and is the leading cause of burned 3-4 clutches, and it will burn up a new kit just as fast. Our 700R4 common problems guide walks through that check, and the 700R4 rebuild cost guide lays out what else usually turns up once the case is open, such as a cracked sun shell, a scored drum or a worn pump.
This kit is listed for 700R4 / 4L60 units built from 1987 through 1993. The year of the truck alone is not always enough. Many of these transmissions have been swapped or replaced over the years, and some models offered more than one transmission. Check the ID tag on the case, confirm it is a 700R4 and not a 4L60E (1993 trucks can have either), and send us your year and VIN if you are unsure. For earlier units and other parts, see our 700R4 parts page.
Many builders add a 700R4 shift kit during assembly to sharpen shifts and reduce clutch slip time.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is for the hydraulic 700R4 / 4L60 from 1987 to 1993. The 4L60E is electronically controlled and uses different seals, pistons and a different case. Check the transmission ID tag before ordering.
Yes, it fits the 700R4 servo bore and gives a larger apply area on the 2-4 band for a firmer 1-2 shift. Follow the instruction sheet for the correct apply pin length.
No. It includes seals, gaskets, frictions, steels, the band, filter, bushings, the Corvette servo and a small-hole accumulator piston. The pump, drums, shells and converter are reused if they inspect good, or bought separately.
Most often low line pressure from a misadjusted TV cable, a pump or stator leak, or a flexed input housing backing plate. A new kit will not survive any of those, so check them during assembly.
Use Dexron ATF; a current Dexron-VI fluid is backward compatible. A rebuilt unit with an empty converter takes more than a pan service, so fill, start the engine and top up to the hot mark.
