4L65E Clutch Module, new and ready to install. Fits the 4L65E. Ships fast from the USA.
A 4L60E or 4L65E that slips between gears, flares on the shift or barely pulls into overdrive has usually worn its clutch packs past the point a fluid change can help. This module is a friction and steel combo for 1997-up 4L60E and 4L65E transmissions: new high-energy frictions bonded to steel cores, plus the matching steel plates, in one set. It is the straightforward choice when the old steels came out blued or warped and you want every pack built from new plates. It ships with a 1-year warranty.
Inside a 4L65E, each clutch pack is a stack of lined frictions interleaved with plain steels. When line pressure pushes the piston, the stack clamps and locks one planetary member to another or to the case. The forward clutch drives 1st through 3rd, the 3-4 clutch drives 3rd and 4th, the overrun clutch adds engine braking in manual ranges, and the reverse input and low/reverse packs give you Reverse. Every one of them depends on fresh friction material and flat steels to hold without slipping, and the 3-4 pack is the one that wears out first behind a hard-working V8.
Rule out the simple causes first: a low fluid level, a clogged filter and a pump that is not making pressure all cause slipping that new plates will not fix. Check pressure, pull the pan and look at what is on the magnet. Fine friction dust with dark fluid confirms clutch wear. Our 4L65E 3-4 clutch failure guide covers the most common burnup and its root causes, and the 4L65E Tahoe common problems guide lays out how the same failures show up in GM SUVs.
This combo is built for 1997-up 4L60E and 4L65E transmissions. The application list behind it runs through the GM trucks and SUVs that used this family, including the 1999-2013 Silverado and Sierra 1500, 1997-2010 Tahoe, 1997-2009 Yukon, 2002-2008 Avalanche, 1997-2008 Suburban 1500, 1997-2014 Express and Savana, and 2002-2009 TrailBlazer and Envoy. Because the family stayed in production so long with running changes in drum and piston details, count the frictions and steels in each of your packs and compare thickness and tooth style before installing, or send us your year and VIN and we will check it. Browse the 4L65E parts collection for everything else your rebuild needs.
An overhaul kit supplies the seals and gaskets for this job. If the 3-4 piston bore or turbine shaft fit is worn, a 4L65E input drum keeps the new 3-4 pack from burning again, and a reaction shell is worth replacing if its splines are worn.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. It is a combo module with new frictions and the matching steel plates, so every pack can be built from new plates.
1997-up 4L60E and 4L65E applications, including the Silverado and Sierra 1500, Tahoe, Yukon, Suburban, Avalanche, Express, Savana, TrailBlazer and Envoy. Send your year and VIN if you want it confirmed.
Steels from a transmission that slipped are often heat-blued or warped. New frictions against a distorted steel will not seat evenly and can glaze quickly.
Piston seals, sealing rings and gaskets from an overhaul kit at minimum. Inspect the input housing, sun shell and reaction shell for spline wear while it is apart.
Dexron VI. Soak the frictions in it before assembly and check the level hot once the rebuild is finished.
