4L65E Master Rebuild Kit 2004-2014, new and ready to install. Fits the 4L65E. Ships fast from the USA.
This is the budget-friendly way to overhaul a late 4L65E. If you are rebuilding a 2004-and-newer unit out of a 5.3L or 6.0L Silverado, Sierra, Tahoe, Yukon, Suburban or Avalanche because it slips, flares into 3rd or has started leaking at several seals, this boxed kit covers the soft parts at a lower price than our other late-case kits. The photo shows friction plates, the pan gasket, case and valve body gaskets, metal-clad seals, sealing rings and a range of O-rings. Open the box and compare it with your teardown before you start, so you know which hard parts and steels you still need.
The 2004-and-later 4L65E uses the same four clutch-and-band layout as every 4L60E-family unit: overrun, forward, 3-4 and reverse input clutches, a low-reverse pack and the 2-4 band. What changes on a late unit is the hardware around it. Sonnax notes that GM moved to a thicker reaction carrier bearing, with a matching carrier and output shaft, in March 2007, so parts pulled from different years do not always mix. The rebuild kit restores the friction surfaces and all the seals that hold apply oil, while you inspect the hard parts that set gear train clearance and alignment.
A kit only solves worn soft parts. GM's PIP5340A describes P0894 or P1870 and a harsh 1-2 shift setting on 4L60E and 4L65E trucks after a converter or replacement transmission install, so recent work plus a code does not automatically mean clutches. Check pressure, scan for solenoid codes, and look at the pan. Our 4L65E shift solenoid guide helps separate an electrical fault from a mechanical one, and the 4L65E rebuild cost guide shows which hard parts usually join the job.
The listing covers 2004 to 2014. On the trucks above, the 4L65E (RPO M32) ran through about 2007. The later years in the range are the same late 4L60E-family case used by its sister units, which is why the kit spans so wide. It is not for 2001-2003 4L65E units; those take an earlier kit. Inside 2004-2014, note the 2007 reaction carrier bearing change when you order hard parts, and match every gasket to its part before installing. Send us the year and VIN if you want a fitment check. Everything else for the unit is on the 4L65E collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The product photo shows friction plates, a pan gasket, case and valve body gaskets, metal-clad seals, sealing rings and O-rings in a boxed kit. Compare the contents with your teardown, and order steels or hard parts you find worn.
The kit is built for the late 4L60E-family case that the 4L65E shares. On GM full-size trucks the 4L65E itself ran through about 2007; the later years cover sister units in the same family.
The soft parts are not the issue, but hard parts are. If you replace the carrier, bearing or output shaft, keep the pre-2007 or post-2007 style matched as a set.
No. A 2003 unit takes an earlier-style kit. This one is for 2004 and newer cases.
Clear codes and drive the truck through repeated light-throttle upshifts so the computer adapts shift timing. Use a scan tool to reset adapts if your model supports it.
