Master overhaul kit for the GM 4T65E transaxle with frictions, steels, pistons, filter, gaskets and seals for 1997-up Century, Impala and Monte Carlo.
A 4T65E that slips going into third, flares between gears, takes a second to engage Drive when cold, or leaves a puddle under the front of the car has usually worn out its soft parts all at once. This master kit, part number T06200C, is built for that situation in the Buick Century, Rendezvous, Chevrolet Impala, Monte Carlo and Uplander with the 3.1L, 3.4L, 3.5L, 3.8L or 3.9L V6. The difference from a basic overhaul set is that molded clutch pistons and a pan filter come in the same box as the frictions, steels, gaskets and seals, so every apply circuit is renewed, not just relined.
The 4T65E drives through a chain and sprockets to a planetary set controlled by the input, second, third and fourth clutches plus the bands. Each clutch is squeezed by a piston that seals against its drum with a bonded or molded rubber lip. Once those lips harden with heat and age, apply oil leaks past them, the pack engages slowly, and the plates slip and glaze. Replacing the friction plates alone leaves the leak in place. With new pistons, new frictions and steels, and fresh lip seals, O-rings and sealing rings on the pump, channel plate, case and servo bores, the hydraulic side holds pressure the way it did when the unit was new.
Pull the pan before you commit. Clutch lining and metal on the magnet mean the packs are already gone and a kit is the right call. A clean pan with the same shift complaints points toward the controls, so rule out a sticking pressure control solenoid first with our 4T65E EPC solenoid guide and the wider 4T65E problems and diagnosis guide. If you are weighing a rebuild against a replacement unit, our 4T65E rebuild cost breakdown lays out what drives the price.
The listing covers 1997-up Buick Century and Rendezvous, 1997-up Chevrolet Impala, and 1997-2007 Monte Carlo and Uplander with 3.1L, 3.4L, 3.5L, 3.8L and 3.9L V6 engines. The 4T65E was also used in the Grand Prix, Bonneville, LaCrosse, Regal, Aztek, Montana, Venture, Silhouette and Terraza. Because the range spans 1997 onward, pay attention to the input freewheel: Transmission Digest reports that GM switched from an input sprag to a pawl clutch at the start of 2003 production, and the input friction that mates with the pawl design has 30 teeth instead of 32. Count the teeth on your old input frictions against the kit before you start stacking. When in doubt, send us your year and VIN. Every other part we stock for this unit is on the 4T65E parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. T06200C includes friction plates, steel plates, molded clutch pistons, a pan filter, gaskets, O-rings, lip seals and sealing rings. Fluid is not included.
Those cars use the 4T65E, but the listing names the Century, Rendezvous, Impala, Monte Carlo and Uplander. Compare the input friction tooth count and your old parts with the kit, or send us your year and VIN before ordering.
The lip on a 4T65E piston hardens with heat long before it looks damaged. A hard lip leaks apply oil, which slips the new frictions you just installed.
Dexron VI. Flush the cooler and lines first so old clutch debris does not go back into the rebuilt unit.
It is strongly recommended. Clearing the old shift adapts lets the computer learn new values for the fresh clutches instead of carrying over the high pressure it used on the worn ones.
