Five-piece REMCO overhaul kit for 1982-1993 TH700-R4 and 4L60E units: gasket set, high-friction clutch pack, flex band, pump bushing and filter.
Rebuilding the overdrive automatic out of an 1980s or early-1990s Chevy or GMC C/K pickup, Blazer, Suburban, S10, Astro, Camaro, Caprice or Corvette? Through 1992 that unit was the hydraulically controlled 700-R4 (renamed 4L60), and the electronic 4L60E took over around the 1993 model year. This REMCO kit, part number RK700R4, is built for that early range, 1982 through 1993. It packs the five things a high-mileage unit consumes on a teardown: the overhaul gasket and seal set, a high-friction clutch pack, a red two-tang 2-4 band, a babbitt pump bushing and a new filter.
Every gear in this transmission depends on oil being held in the right circuit and friction surfaces that can grip. The gasket and seal set reseals the pump, case, servo and accumulator covers, and the rubber and Teflon seals on each clutch piston, so apply pressure stops leaking away. The clutch pack supplies new frictions for the forward, 3-4, overrun, low/reverse and reverse input clutches. The 2-4 band wraps the reverse input drum and holds it for 2nd and 4th gear. The pump bushing supports the converter hub at the front of the pump; when it wears, the pump gear runs off-center and the front seal starts to leak. What is not included: steel separator plates. If your steels are blued, coned or scored, buy them separately before you start.
Check the fluid level and condition, then drop the pan. Friction material and a burnt smell mean the clutches or band are finished; large chunks of steel, a broken sun shell or a damaged drum mean you need hard parts as well, so price those before you commit. On a 1993 4L60E, scan for codes before teardown, because a failed shift solenoid can mimic a mechanical slip. Our 4L60E common problems guide matches each symptom to the part behind it, and the 3-4 clutch pack diagnosis guide explains why a 3-4 pack that burns once will burn again unless line pressure and sealing are fixed.
This kit is listed for TH700-R4, 4L60, 4L60E and 4L65E units built from 1982 to 1993. In practice the 4L65E did not arrive until well after that, so the realistic application is the 700-R4/4L60 and the first-year 4L60E. GM made running changes inside this range, and manufacturer data shows the forward and reverse input friction designs changed in the mid-1980s, so count your existing frictions per pack and compare tooth count and diameter before you assemble. Confirm the identification tag on the case rather than going by vehicle year alone, and if you are unsure send us the year and VIN. If your unit is 1993 or later, browse the later kits on our 4L60E parts page.
The kit ships at about 5.7 lb with a printed inventory sheet, so count every piece against the list before you tear the transmission down.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It includes the gasket and seal set, high-friction clutch pack, red two-tang flex band, pump bushing and filter. Steel plates are sold separately.
It is listed for 1982-1993 units. Later 4L60Es changed seals, pans and internal parts, so use one of our 1993-and-later 4L60E kits for a 1994 or newer transmission.
A 700-R4 or 4L60 has a TV cable at the side of the case and no wiring harness connector for shift solenoids. A 4L60E has an electrical connector on the case and no TV cable. Check the ID tag on the case as well.
Dexron VI is the current GM fluid and is backward compatible with earlier Dexron specifications used in these transmissions. Soak the frictions and band in it before assembly.
Replace any blued or coned steels, inspect the drums and sun shell for damage, and check the input sprag. Fix any line pressure problem so the new 3-4 clutches do not burn again.
