4L85E Clutch Module 1995, new and ready to install. Fits the 4L85E. Ships fast from the USA.
A 1995 Chevrolet or GMC 2500 or 3500 pickup, Suburban or full-size van with the heavy-duty electronic four-speed that now flares between gears, slides into Reverse or smells burnt after a tow is telling you the clutch packs have worn through their lining. This is a new friction module, listing reference R34119, listed for 1995. That year deserves its own page, because 1995 is the year GM changed both the friction packs and part of the valve body in this transmission.
The heavy-duty four-speed GM sold in these trucks is the 4L80E, a Turbo 400 with an overdrive section added at the front. The 4L85E that came later uses the same five clutch packs: overrun and fourth in the overdrive section, then forward, direct and intermediate in the main case. Each pack alternates lined frictions with steel plates, and apply oil squeezes the stack to hold or drive a planetary member. The module supplies the lined plates. The photo shows several diameters and lining colors because each position has its own size and spline; the plates are not interchangeable between packs, so keep the old stacks in order as you tear down.
Note which ranges slip and compare them to the clutch apply chart in our 4L85E and 4L80E problems guide. Then look for the cause, not just the damage. Sonnax fits its reverse checkball sleeve repair to 1995-and-later units, where the sleeve sits in the 3-4 shift valve bore, and a worn sleeve leaks direct clutch apply oil, producing 3rd and 4th slip and a burnt direct pack. Our 3-4 clutch failure guide explains how to check it. If the slip came with a dirty, overdue fluid change, our filter and pan service guide shows what to look for in the pan.
The listing is for 1995 units of the 4L80E family. GM did not build a 4L85E until about 2002, so any 1995 truck has a 4L80E, and the clutch packs are shared across the family. Year alone is not enough here. Raybestos catalogs two different 4L80E friction modules, one for 1991 to early 1995 and one for late 1995 onward, which means two 1995 trucks can need different plates. Before you buy, compare the R34119 reference with your old plates or the kit you used last time, or send us your VIN and the number on the transmission tag and we will confirm it. Early 1995 and older units may be better served by our 1990-1996 friction module, and the full range of parts for this family is on the 4L85E collection page.
Refill with DEXRON VI, set the level with the fluid at operating temperature, and give the controller several drive cycles to adapt before you judge shift feel.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
1995 straddles a production change. Raybestos lists one 4L80E friction module for 1991 to early 1995 and another for late 1995 on, so check your old plates against the R34119 reference or send your VIN and transmission tag before ordering.
A 4L80E. The 4L85E arrived around 2002 as a heavy-duty version with five-pinion planetaries, but it shares the same clutch pack design, which is why this part sits in our 4L85E category.
Only if the cause is fixed too. Those three gears share the direct clutch, and on 1995-later units a worn reverse checkball sleeve can bleed its apply oil. Replace or repair the sleeve and check the drum bore, or the new direct pack will burn.
A master rebuild kit for seals and gaskets, steel plates if yours are blued or warped, and a new filter. Many towing trucks also get a shift kit.
Use DEXRON VI for soaking the frictions and for the refill, and check the level hot.
