4L80E Clutch Module 1991-1995, new and ready to install. Fits the 4L80E. Ships fast from the USA.
An early 4L80E that slips on the 1-2 or 2-3 shift when towing, flares between gears or leaves a burnt smell on the dipstick has almost always cooked its clutch frictions. This is a complete Raybestos Stage-1 friction clutch pack, part number RCPS-31, for the first generation 4L80E built from 1991 through early 1995. That covers the Chevrolet and GMC 2500 and 3500 pickups, Suburban 2500 and full-size vans of that era, including the 6.5L diesel trucks that are hard on transmissions. The red Stage-1 material is a step up from a stock replacement plate, which makes it a good choice for a work truck that pulls a trailer every week.
The 4L80E picks its gears by clamping friction plates against steel plates in five clutch packs, then combining that with two bands and one-way clutches. The forward clutch is applied in every forward gear, the intermediate clutch is added for second, the direct clutch for third, and the fourth clutch for overdrive. The overrun clutch only applies in the manual ranges for engine braking. When a friction glazes or loses lining, that pack slips under load, heat climbs and the damage spreads to the other packs. The RCPS-31 module replaces every friction in the unit in one box: ten forward and direct plates at .080 inch, four fourth clutch plates, four intermediate plates at .090 inch and three overrun plates. Raybestos says its Stage-1 frictions add holding capacity and tolerate the higher temperatures that come with towing, compared with a stock tan or high-energy plate.
For the most common early-unit pattern, read our 4L80E 3-4 clutch failure guide before you order.
Pull the pan. A layer of fine dark paste on the magnet is normal; flakes of lining and a strong burnt smell are not. A line pressure test then tells you whether the frictions burnt because of low pressure, which has to be fixed at the same time or the new pack will burn too. Our 4L80E common problems guide covers the pressure and lube faults that kill clutch packs.
Raybestos catalogs RCPS-31 for the 4L80E from 1991 to early 1995. Units built in late 1995 and later take a different pack, RCPS-36, so a 1995 truck needs its build date checked before ordering. Match the transmission tag, count your old frictions at teardown, or send us your year and VIN and we will confirm. Every 4L80E part we stock is on the 4L80E collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Only an early 1995 unit. Raybestos splits the 4L80E in 1995: RCPS-31 covers 1991 to early 1995 and RCPS-36 covers late 1995 and later. Check the build date on your transmission tag or send us your VIN.
Ten forward and direct frictions at .080 inch, four fourth clutch frictions, four intermediate frictions at .090 inch and three overrun frictions. Steel plates are not included.
No. Raybestos positions Stage-1 as a drop-in plate that adds holding capacity and heat tolerance over stock, suited to towing and mild performance use.
Reuse steels only if they are flat and free of heat marks. Most burnt-clutch rebuilds replace them with a matching steel module.
Dexron VI, which GM now lists as the service fluid for the 4L80E. Soak the frictions in the same fluid before assembly.
