4L70E Shift Kit 2004, new and ready to install. Fits the 4L70E. Ships fast from the USA.
This listing sits with our shift kits, but what ships is bigger than a shift kit: it is a complete Toledo Trans-Kit master rebuild kit for the 2004-and-later GM 4L60E, 4L65E and 4L70E (part HDK6100HBFP). If a Silverado, Sierra, Tahoe, Yukon, Trailblazer, Envoy, Colorado, Canyon or Hummer H3 has started slipping, flaring into third, smelling burnt on the dipstick or losing a gear, the clutches and seals are worn out and a valve body calibration kit alone will not bring them back. This box holds the parts that do.
The 4L70E holds every gear with friction clutch packs, one band and rubber-bonded pistons, all fed by line pressure through sealing rings and gaskets. When fluid breaks down, those are the parts that wear first. According to the listing, this kit includes:
That is everything soft that wears inside the unit. It is the same scope a shop would order before tearing a 4L70E down to the case.
Check fluid level and condition first, then pull trouble codes. A worn electrical part can mimic a mechanical failure, so rule out the pressure control solenoid and wiring before committing to a teardown. Sonnax traces most burnt 3-4 clutches in this family to low line pressure and third-gear oil leaks rather than to the clutches themselves, so a rebuild that only replaces frictions can burn up again. Our 4L70E 3-4 clutch failure guide walks through the checks, and the 4L70E common problems guide covers the rest of the list.
The kit is listed for 2004-and-later 4L60E, 4L65E and 4L70E transmissions in two- and four-wheel drive, including Colorado, Canyon, Trailblazer, Envoy, Isuzu i-Series, Hummer H3 and the full-size Silverado, Sierra, Tahoe and Yukon. Earlier units use a different overhaul gasket set, so a pre-2004 transmission needs the earlier kit. The supplied filter is the 4WD stepped deep-pan style; if your pan is the shallow style, use the filter that matches it. Clutch pack counts also changed across the family, so lay the old packs out and count them before you build. Send us your year and VIN if you are unsure, and see every part for this unit on the 4L70E parts page.
A master kit is a full overhaul, not a bolt-in job. Soak the frictions in clean fluid before assembly, set clutch clearances to spec, and check input endplay before closing the case. Hard parts decide whether the rebuild lasts: inspect the reaction sun shell for cracked or stripped splines and replace it with a 4L70E sun shell if needed, and check the input housing for bore wear, a leaking checkball or loose 3-4 piston seals, replacing it with an input drum if it fails. Flush the cooler and lines, then fill with Dexron VI and set the level hot.

It is a complete master rebuild kit for the 2004-up 4L60E, 4L65E and 4L70E: gaskets and seals, a piston kit, Raybestos frictions, steel plates, a 2-4 band and a filter. It does not include valve body calibration parts.
The kit is listed for 2004-and-later 4L60E, 4L65E and 4L70E units, which covers those trucks. Count your clutch plates during teardown and send us your year and VIN if anything does not match.
Inspect the reaction sun shell, input housing, pump and planetary sets. Cracked sun shells and leaking input housings are common in this family and will ruin new clutches if reused.
No. Clutches, pistons and the band are inside the case, so the transmission has to come out and be fully disassembled.
GM specifies Dexron VI automatic transmission fluid. Flush the cooler and lines first so old debris does not reach the new clutches.
