GM 4T65E Transmission Master Rebuild Kit, Raybestos 2003-Up

This is a full master kit for the GM 4T65E four-speed front-wheel-drive transaxle, covering the 2003-up units with the updated valve body and case castings. It is the transmission behind a long list of GM cars and vans: Impala, Monte Carlo, Grand Prix, Bonneville, LaCrosse, Allure, Regal, Century, Rendezvous, Aztek, Malibu Maxx, Montana, Terraza, Silhouette, Venture and Uplander, along with the Volvo XC90 and S80 that use the same transaxle behind the 3.1L through 3.8L engines.

Unlike an overhaul-only set, this kit gives you everything for a full reline: a Raybestos Powertrain friction clutch pack module, a matching steel clutch pack module, and the complete gasket, seal, O-ring, lip seal and sealing ring package. On the bench you use it to reline all the clutch and band packs, replace the steels, and reseal the pump, case and channel plate during teardown and reassembly.

It addresses the failures that put a 4T65E on the bench: slipping in third and fourth, loss of reverse, a burnt forward or direct clutch, and the fluid-cut sealing rings that cause pressure loss and shift codes on high-mileage 3.5L and 3.8L cars. You supply fresh Dexron-VI fluid and any hard parts your teardown turns up; the frictions, steels, and every soft part are in the box.
