4L80E Clutch Module 1990-1996, new and ready to install. Fits the 4L80E. Ships fast from the USA.
An early 4L80E in a 1990s Chevrolet or GMC 2500 or 3500, a Suburban 2500, a full-size van or a Hummer that now slips when it is warm, bangs into gear late or leaves black, burnt-smelling fluid on the dipstick needs new friction plates. This is a new friction clutch module, reference A34119A (industry number 031752A), listed for 1990 through 1996 4L80E and 4L85E units. It is a stock-replacement set of frictions for a rebuild, made by Alto, and when supply is tight an equivalent Allomatic or Raybestos module may be supplied in its place.
The 4L80E builds each gear by applying clutch packs and bands around three planetary sets. Inside each clutch pack, lined friction plates alternate with plain steel plates. Hydraulic pressure pushes a piston against the stack and the two kinds of plate lock together, driving or holding a planetary member. When the lining wears thin, a pack takes longer to lock up, the slip makes heat, and that heat glazes the next pack and breaks down the fluid. A friction module gives you every friction for the unit in one box, so a rebuild does not have to mix new plates with tired ones.
Pull the pan before you commit to a rebuild. Lining flakes, a heavy layer of dark paste on the magnet and a burnt smell point at the clutch packs. A pressure test tells you why they wore out. On these early units, worn valve body bores, bushings and accumulator pistons all bleed off pressure and starve the clutches, and those leaks must be repaired or the new plates will burn too. The 4L80E common problems guide and the Sierra 2500 4L80E problem guide explain how to track the root cause down.
This module is listed for 4L80E and 4L85E transmissions from 1990 to 1996. The catch is 1995. Raybestos, for one, splits its 4L80E friction packs at a mid-1995 production change, with a different intermediate friction before and after it, so a 1995 or 1996 unit should be checked before you order. Compare the plates you take out with the photos, read the build date on the transmission ID tag, or send us your year and VIN and we will confirm the match. If your unit is on the later side of the change, the 1997-2009 4L80E clutch module is the one to look at. Everything we stock for this transmission is on the 4L80E collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. The A34119A module is listed for both the 4L80E and the 4L85E in the 1990-1996 range.
Possibly. 4L80E friction packs changed during 1995 production, so check the build date on the transmission tag or compare your old intermediate plates first. Send us your year and VIN and we will confirm before it ships.
No, this is a friction module only. Reuse your steels if they are flat and unmarked, or add the matching steel plate kit.
The listed module is made by Alto. When it is short, an equivalent friction module from Allomatic or Raybestos for the same application may be substituted.
Piston seals, gaskets, the filter and any worn bushings. Low pressure from leaking seals or bushings is a common reason early 4L80E clutches burn.
