4T65E Transmission Master Rebuild Kit, GM 3.4/3.5/3.8L 2001-2003

This is a master rebuild kit for the GM 4T65E four-speed transaxle, the transverse automatic GM ran behind the 3.1L, 3.4L, 3.5L, and 3.8L V6 in its front-drive cars. It covers the everyday failure that puts these units on the bench: worn frictions and hard parts that show up as a slipping or flaring 1-2 or 3-4 shift, a shudder, or a code for the 3-5 reverse or forward clutch. Corresponds to OE overhaul number 4T65E T06200C (T06202C, T062080C, T062081C).

The kit is built to the 2001-2003 3.4/3.5/3.8L applications: Buick Century, LeSabre, Park Avenue, and Rendezvous; Chevrolet Impala and Monte Carlo; Oldsmobile Aurora, Intrigue, and Silhouette; and Pontiac Aztek, Bonneville, Grand Prix, and Montana. Confirm your unit against those years and engines before you order, because GM revised the 4T65E clutch and drum stackup across its run.

Contents cover a full overhaul: the friction clutch pack, bonded and rubber piston seals, sealing rings, metal-clad seals, the paper and rubber gasket set, O-rings, the coast band, and the transmission filter. On the bench you air-check each clutch drum after you reseal it, set clutch clearance to spec as you stack the packs, drop in the new frictions and band, and finish with the filter and pan gasket before the unit goes back in. Do the reseal and clutch job once with matched parts instead of chasing the same slip twice. Ships from the USA, handling in 1-2 business days.
