4L80E Sprag Clutch 1996-01, new and ready to install. Fits the 4L80E. Ships fast from the USA.
This is a full set of new one-way clutches for a 1996 to 2001 4L80E, the kind you order when the unit is on the bench and you want every freewheel in it fresh. It covers 2500 and 3500 Silverado, Sierra and C/K pickups, Suburban 2500, Express and Savana vans and the Hummer H1 from those years. Buyers usually arrive here after a no-1st, a neutral 1-2 shift or a no-drive in Drive, and a teardown that showed one sprag gone and debris everywhere.
Manufacturer numbers on the listing are 06763AM and 40971AM.
Each of the three handles a different gear. The overdrive roller clutch sits in the overrun drum and holds the overdrive planetary in 1st through 3rd, then freewheels in 4th. The intermediate sprag rides in the direct drum: when the intermediate clutch applies for 2nd, the sprag is what actually holds the sun gear, and it lets go on the 2-3 shift so there is no tie-up. The low roller clutch at the rear holds the rear carrier for 1st in Drive and freewheels once 2nd takes over. That is why one failed element shows up in only one gear range.
Start with fluid level and line pressure, because low apply pressure burns the intermediate clutch and can make a good sprag look guilty. Then road test each range: Drive versus manual 3 isolates the overdrive roller, and Drive versus manual 1 isolates the low roller. A slip only on the 1-2 shift points to the intermediate clutch or sprag. The Silverado 2500 shift problems guide lays out that range-by-range check, and the 4L80E common problems guide covers pressure testing.
Built for 4L80E transmissions from 1996 through 2001. The 1996 cutoff comes from the low roller clutch, since earlier units use the earlier low roller; the 2001 end comes from the overdrive roller clutch, which is listed only through 2001. Some 1995 units were built with the later parts, so if your truck sits at either edge of that range, compare the old low roller legs and the overdrive roller against these, or send your year and VIN. For 1991 to 1995 transmissions the early low and intermediate sprag set is the right match. Browse more on the 4L80E collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Three: the 8-leg low roller clutch for 1996 and later, a 34-element heavy-duty intermediate sprag, and the overdrive roller clutch with 0.309 in. rollers listed for 1991 through 2001.
The low roller clutch in this set is listed for 1996 and later. Some late 1995 units may already use it, so compare the legs on your old low roller or send us the year and VIN. Most 1991 to 1995 units take the early set.
It often is, but check line pressure and the intermediate clutch pack first. The sprag only holds when the intermediate clutch applies, so a burnt pack gives the same flare. Inspect the sprag races at teardown too.
Yes. It replaces the 16-element style found in earlier builds, and more elements spread the load for towing and higher-torque engines.
Dexron VI ATF. Check it hot on the dipstick after the truck reaches operating temperature.
The low and intermediate pieces fit later units, but the overdrive roller clutch in this set is listed only through 2001, so later units may need a different overdrive roller.
