Full 4L60E overhaul kit: 22 frictions, 21 steels, 2-4 brake band, filter, separator plate, pistons and the complete gasket and seal set.
If your Silverado, Tahoe, S10, Astro or TrailBlazer has started flaring between 1st and 2nd, lost 3rd and 4th, or dumped dark fluid full of friction material into the pan, the transmission is past the point of a fluid change. This master kit is built for the bench job that follows: it puts 22 friction plates, 21 steel plates, a new 2-4 brake band, a separator plate, a filter, a piston set and the full gasket and seal kit in one box, so every clutch pack in the 4L60E gets renewed at once instead of being patched one pack at a time.
The 4L60E uses five multi-plate clutches (reverse input, forward, overrun, 3-4 and low/reverse) plus one band, the 2-4 band, which wraps the reverse input drum to hold it for 2nd and 4th gear. Every one of those friction surfaces wears together, and when one burns the debris it sheds circulates through the rest of the unit. That is why a master kit makes sense here: the frictions and steels cover the packs, the band covers 2nd and 4th, and the seal set restores the pressure that the pistons need to clamp each pack. The separator plate is a nice inclusion, because a worn or eroded plate between the valve body and case can leak apply oil even after the clutches are new.
What it does not include matters just as much. There is no sun shell, pump, valve body, solenoid set or converter in this box. On a high-mileage 4L60E the reaction sun shell and the 3-4 clutch hub are the hard parts that fail most often, so inspect them before you commit to reassembly.
Pull the pan before you order. Fine gray paste on the magnet is normal wear; flakes of friction lining, chunks of band material or bright metal mean the unit is coming apart inside. Scan for codes too. A P1870 on its own can point to valve body bore wear in the TCC regulator circuit rather than burned clutches, and P0748 points at the pressure control solenoid. Our guide 4L60E Common Problems, Symptoms, and What to Actually Do About Them walks through which complaints need a teardown and which can be fixed with the transmission still in the truck.
The listing covers the 4L60 and 4L60E family, the 4L65E, 4L70E and 4L75E heavy-duty variants, and also names the 700R4. Listed applications include 1994-2005 S10, Blazer and Jimmy 4.3L; 1994-2005 Astro and Safari; 1999-2013 Silverado and Sierra 1500 with the 4.3, 4.8, 5.3 and 6.0L; 1995-2014 Tahoe, Suburban and Yukon; 2002-2009 TrailBlazer and Envoy; 2002-2008 Avalanche; 1999-2006 Escalade, ESV and EXT; and Corvette C4 and C5. It crosses to T05700B, T057080B, T057081B, KP33900M and M31.
Because one kit spans more than twenty model years, be honest with yourself about the 1993-2003 and 2004-up split. GM changed several internal parts in 2004, including valve body gaskets and piston styles, so compare the separator plate and gaskets in the box to the ones you pull out before you seal the case. The 700R4 is the older hydraulic unit with no shift solenoids, so confirm the pieces match before using it there. If you are unsure, send us your year and VIN and we will check it. You can browse every kit and hard part for this unit on our 4L60E parts page.
Parts worth buying with this kit: a Raybestos Kevlar 2-4 band if you want a heavier-duty band than the stock-style one in the box, and the 4th gear super hold servo kit to put more apply force on that band in 4th. If you have never built one of these, read the bench tools you actually need first, and see our 2-4 band and servo guide for pin selection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. A new 2-4 brake band is included along with 22 friction plates, 21 steel plates, a separator plate, a filter, a piston set and the complete gasket and seal kit.
The kit is listed for 1993-2003 and 2004-up units, but GM changed valve body gaskets and some piston parts in 2004. Lay the new separator plate and gaskets next to the old ones before assembly, or send us your year and VIN so we can confirm before it ships.
No. This is a soft-parts and clutch master kit. The sun shell, pump, valve body, solenoids and converter are not included, so inspect those hard parts during teardown.
Use Dexron VI automatic transmission fluid. Fill the unit, start the engine and run it through the gears, then set the final level hot on the dipstick.
Sometimes. P1870 can come from a worn 3-4 pack and low apply pressure, which this kit addresses, but it is also commonly caused by TCC regulator valve bore wear in the valve body. Check the valve body during the rebuild so the code does not come back.
