4L60E Master Rebuild Kit 1993-1996, new and ready to install. Fits the 4L60E. Ships fast from the USA.
Early 4L60E transmissions are now 30 years old, and most of the ones still on the road have been through at least one cheap repair. If you own a 1993-1996 Chevrolet or GMC C/K 1500 pickup, Tahoe, Yukon or Suburban, an S10, Sonoma or Blazer, or a Camaro or Corvette from those years and the transmission is slipping, leaking from several places or has quit pulling 3rd and 4th, this new master rebuild kit is sized for the first-generation unit.
The 4L60E took the proven 700R4 gear train and put it under computer control, so the mechanical layout is familiar: a 2-4 band, a low/reverse clutch, and overrun, forward, 3-4 and reverse input clutch packs in the input housing. What wears out after three decades is mostly rubber and paper. Lip seals harden and shrink, Teflon sealing rings groove, and frictions that have seen high fluid temperatures glaze over. A master kit replaces the frictions, steels, seals and gaskets together so pressure holds in every circuit and every clutch applies with fresh material. On a 1993-1996 unit that has never been fully apart, that is usually the only way to stop the slipping and the leaks at the same time.
Separate clutch failure from electrical and hydraulic faults first. On these early units, a failing pressure control solenoid or a sticking valve can make healthy clutches feel tired. Scan for codes, check fluid level and condition, and if possible put a gauge on line pressure. Our 4L60E shift solenoid symptoms guide covers the electrical side, and the 4L60E common problems guide lists what each failure feels like from the driver's seat. If the truck has no 3rd or 4th and the pan is full of debris, go straight to the overhaul.
This kit is listed for 1993-1996 4L60E units. The early transmissions differ from later ones in ways that matter during a rebuild. Sonnax splits TCC solenoid parts at '96-earlier versus '97-later, because the PWM torque converter clutch became standard from 1997. Valve bodies from 1993-1995 use a different 3-2 control setup than 1996-later bodies, and Sonnax notes that early cases without shifter bracket bosses cannot be used in 1996-1997 vehicles. Because of those running changes, compare the gaskets in the kit against your case and valve body before final assembly, and send us the year and VIN if you are unsure what you have. For a 1997-2003 transmission, look at the 1997-2003 master rebuild kit. All parts for this unit are on our 4L60E collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Buy the kit listed for your year. The 1993-1996 units differ from later ones in TCC control and valve body details, and gasket and seal shapes followed those changes. This kit is the one listed for 1993-1996.
Common ones are the Chevrolet and GMC C/K 1500 pickups, Tahoe, Yukon and Suburban, the S10, Sonoma and Blazer, and V8 Camaro and Corvette models. Confirm by the RPO code on the glovebox or door sticker, or send us the VIN.
Yes. Dexron VI is GM's current spec and is approved as a replacement for the earlier Dexron fluids in these transmissions.
Inspect and replace as needed the sun shell, bushings, forward sprag and pump parts. Many builders also upgrade the 3-4 clutch pack, and a worn pressure control solenoid should be replaced while the pan is off.
The two most common causes are a burned 3-4 clutch pack and stripped splines on the sun shell. Both require teardown, which is why most owners do the full overhaul at that point.
