4T60E Clutch Module 1994-1999, new and ready to install. Fits the 4T60E. Ships fast from the USA.
The GM 4T60E was the electronic four-speed in a long list of front-drive Buick, Oldsmobile, Pontiac and Chevrolet cars until the 4T65E took over late in the decade. By now most surviving units have well over 100,000 miles, and the usual complaint is a car that slips when warm, flares between gears or smells burnt. This is a new, complete friction clutch kit for the 1994-1999 4T60E, with every friction the unit needs supplied as one matched set from a major American friction maker (Borg, Raybestos, Allomatic or Alto, whichever is in stock). It is listed specifically for the 4T60E and will not fit a 4T65E.
Inside the 4T60E, four multi-plate clutches (input, 2nd, 3rd and 4th) and two bands control the planetary gear train. Each clutch pack alternates lined frictions with plain steels, and the PCM-controlled hydraulics apply them in combinations to select each gear. Raybestos catalogs a 1995-on 4T60E friction module as six high-energy 2nd clutch plates, two graphitic 4th clutch plates, four tan input clutch plates and ten high-energy 3rd clutch plates, which shows how the work is split: the 2nd clutch carries the load on every upshift past first, while the 4th clutch uses a graphitic lining suited to its overdrive duty. A complete kit replaces all of those at once so no pack goes back in with tired material.
Confirm the frictions are the problem, not the hydraulics feeding them. Sonnax's 4T60-E valve body layout links low line rise and soft shifts with 2nd and 3rd clutch distress, which means a worn boost valve or regulator bore can burn new clutches just as fast as the old ones. Check fluid level and condition, look at the pan magnet, and if the car still drives, note which gears slip. Our delayed engagement guide and the 4T65E common problems guide walk through checks that apply equally to the older 4T60E, since the two share their basic layout.
This kit fits the GM 4T60E from 1994 through 1999. It is not for the 4T65E, which replaced the 4T60E in many of the same cars from 1997, so a 1997-1999 Buick, Pontiac or Oldsmobile can have either unit. Read the ID tag on the case, and if you cannot tell, send us your year and VIN before ordering. Raybestos separates 1991-1995 and 1995-on 4T60E friction modules, so on a 1994 or early 1995 unit compare the new plates against the originals before assembly. If you are rebuilding an earlier car, see the 4T60E clutch module for 1991-1999, and find other parts for this family on the 4T65E and 4T60E parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The kit is made for the 4T60E only. The 4T65E uses different clutch packs, so check the ID tag on the transaxle case or send us your year and VIN if you are unsure which unit you have.
GM moved many of the same cars to the 4T65E during those years. The ID tag on the case is the reliable answer; the year and VIN will also identify it.
No, it is the friction plate set. Reuse steels only if they are flat and unburnt, and pair it with an overhaul seal kit and a new filter and pan gasket.
The 4T60E originally called for Dexron III. GM made Dexron VI back-serviceable for those transmissions, so a Dexron VI fluid is the current choice. Check the level hot.
Low or unstable line pressure is a common cause. Worn valve body bores, a weak pump or leaking seals let clutches slip and overheat, so fix those during the rebuild or the new frictions will fail the same way.
