4L60E Clutch Module 2001, new and ready to install. Fits the 4L60E. Ships fast from the USA.
A 2001 4L60E is most likely sitting behind a Vortec V8 in a GMT800 Silverado or Sierra 1500, a Tahoe, Yukon or Suburban, or behind the 4.3 in an S10, Sonoma or Blazer. It also backed the LS1 in the 2001 Camaro, Firebird and C5 Corvette. Twenty-plus years on, plenty of these are coming apart with burnt clutches, and this new Alto clutch module is the friction replacement for that rebuild. It is made for the 2001 model year and sold new with a 1-year warranty.
Alto is one of the established friction suppliers to the transmission rebuild trade, and the product photo shows plates in Alto packaging in two stacks. We have not published a full plate-by-plate breakdown for this listing, so plan on it covering the friction side only, and source seals, gaskets and a filter separately. If you want the exact contents confirmed against your teardown before ordering, contact us.
The 2001 unit uses the same clutch layout as every 4L60E: forward, overrun, 3-4, reverse input and low-reverse clutch packs, with the 2-4 band and two one-way clutches filling in the rest. The overrun clutch is worth understanding on these trucks. Gears Magazine points out that the 4L60E has no overrun clutch solenoid; the manual valve and 4-3 sequence valve route oil to it, so it applies for engine braking in the manual ranges. The 3-4 pack, meanwhile, applies on the 2-3 shift and carries torque all the way through overdrive, which is why it is usually the first pack to burn on a truck that tows or runs a lot of highway miles.
On this year, also look at the electrical side before blaming clutches. A failing pressure control solenoid sets P0748 and can produce soft, slipping shifts that cook a fresh pack, and valve body bore wear causes TCC slip with P0741.
Scan for codes, then pull the pan and look at the debris. Friction material on the magnet means clutches; steel or brass means hard parts are involved. Once the transmission is apart, air check each drum and inspect the sun shell, the forward sprag and the low roller clutch. Our low-reverse clutch failure guide covers the no-reverse case, and the overrun clutch guide explains the engine-braking complaints in detail.
Listed for the 2001 4L60E. That covers 2001 Chevrolet Silverado 1500, Tahoe, Suburban, S10, Blazer, Camaro and Corvette, and GMC Sierra 1500, Yukon and Sonoma with this transmission. The 4L60E had running changes through its life, and plate counts in the 3-4 pack can vary between V6 and V8 applications, so check the plates in your old packs against the module before assembly, or send us the year and VIN. Other 4L60E parts are on our 4L60E shop page.
Refill with Dexron VI, check the level hot, and break the new plates in with easy driving before towing.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes, it is listed for the 2001 4L60E, which includes the 2001 Silverado and Sierra 1500. Compare plate counts with your old packs before assembly.
It is a friction module in Alto packaging. We have not published a plate-by-plate count; contact us and we will confirm the contents before you order.
If you have P0748 or soft shifts, yes. A weak pressure control solenoid lets the new clutches slip. Replacing the internal harness while the pan is off is also cheap insurance.
That usually points to the overrun clutch, which the 4L60E applies hydraulically in the manual ranges. Burnt overrun frictions or a cracked overrun hub are the common causes.
Use Dexron VI ATF, which replaces the older Dexron grades, and soak the frictions in it before assembly.
