4T65E Clutch Module 1998-2002, new and ready to install. Fits the 4T65E. Ships fast from the USA.
A 1998-2002 Impala, Grand Prix, LeSabre, Century or Monte Carlo that revs up between gears, slips once it is warm, or leaves dark, burnt-smelling fluid on the dipstick has usually worn through its friction plates. This listing is a new, complete friction clutch kit for the pre-2003 GM 4T65E: every friction the transaxle uses, in one box, built by one of the major American friction makers (Borg, Raybestos, Allomatic or Alto, depending on what is on the shelf when your order ships). It is the set you want if the unit is coming apart anyway and you do not want to piece frictions together pack by pack.
The 4T65E builds its four forward ratios (2.92, 1.56, 1.00 and 0.70) by holding or driving parts of its planetary gear train with multi-plate clutches and bands. Each clutch is a stack of lined friction plates interleaved with steel plates; oil pressure pushes a piston against the stack and the plates lock together. The frictions are the wear item. Raybestos catalogs the 1999-2002 friction module as six 2nd clutch plates, four input clutch plates in tan material, four 4th clutch plates and ten 3rd clutch plates, nearly all in high-energy lining that resists heat on long, loaded shifts. This kit follows that early design: it uses the normal forward and input clutch spline and includes two double-sided overdrive (4th) frictions, lined on both faces.
Frictions are often the victim, not the cause. A worn AFL valve bore in the channel plate starves the pressure control solenoid and can burn a healthy clutch; Sonnax ties that wear to P1811 and falling out of 4th. A stripped 4th clutch hub can also give a no-4th complaint with clean frictions. Drop the pan first, then check adapts and shift times with a scan tool. Our 4T65E 3-4 clutch failure guide covers reading those numbers, and the EPC solenoid symptoms guide covers the pressure faults to rule out.
The listing is for the GM 4T65E from 1998 through 2002 (the kit's description also covers 1997 units with the same internals). Two exceptions matter. In 2003 some 4T65E units moved to a mechanical diode input sprag with a different forward clutch spline, so a 2003-on transaxle may need the 4T65E clutch module for 2003 instead. It is also not for Volvo applications or any unit that uses one-sided overdrive clutches. Lay a new plate next to an old one and compare the teeth and lining before you stack anything, or send us your year and VIN and we will check it. More early-model parts are on the 4T65E parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Possibly not. Starting in 2003 some 4T65E units used a mechanical diode input sprag with a different forward clutch spline. This kit uses the earlier spline, so for 2003-on units compare the old plates to the new ones or choose the 2003 clutch module.
Yes. The kit includes two double-sided overdrive frictions, lined on both faces. Units that use one-sided overdrive plates, including Volvo applications, need a different set.
No. This is the friction plate set only. Reuse steels only if they are flat and not heat-blued, and replace piston seals and sealing rings from an overhaul or master rebuild kit.
DEXRON-VI. GM lists about 7.4 quarts (7.0 L) for a 4T65E service fill and more if the converter was drained. Check the level with the fluid hot, around 180-200 F.
Yes. Clear the shift adapts with a scan tool or by disconnecting the battery, then drive through a range of normal shifts so the PCM can relearn apply pressure on the new frictions.
