4T65E Clutch Module 2003, new and ready to install. Fits the 4T65E. Ships fast from the USA.
If you are rebuilding the 4T65E out of a 2003 or later Chevrolet Impala or Monte Carlo, Pontiac Grand Prix, Buick LeSabre, Century, Regal or Rendezvous, or a GM minivan, and it came apart with burnt clutches after slipping, flaring or taking forever to shift, this friction clutch kit is matched to the design GM introduced for 2003. It contains the lined plates for the clutch packs, including the input clutch frictions that mate with the later pawl-type input one-way clutch. The kit is assembled from BorgWarner, Raybestos, Allomatic or Alto stock depending on availability, always as one complete set for this application.
The 4T65E uses input, 2nd, 3rd and 4th clutch packs plus bands and one-way clutches. Through 2002 the input and third one-way clutches were sprag designs. Transmission Digest reports that GM switched to input and third pawl-clutch assemblies at the start of 2003 production, a design some catalogs call a mechanical diode. The new input pawl outer race went from 32 splines to 30, so the input clutch friction that mates with it changed from 32 teeth to 30. A kit built for 1997-2002 will not seat on a pawl-type input, and that tooth count is the reason this listing is separated by year. The third clutch plates did not change with the pawl clutch.
Transmission Digest also lays out the other packs: the 2nd clutch runs six friction discs against five steels, and the 3rd clutch uses five driving and five driven plates that each carry friction on one side.
Scan for codes and watch shift times on live data. Debris on the magnet confirms clutch wear, but a long shift on a clean unit can be hydraulic: Sonnax links a worn actuator feed limit bore in the channel plate to P1811, second-gear starts and dropping out of fourth. Our 4T65E 3-4 clutch failure guide covers the long-shift codes in detail, and the pressure control solenoid guide helps separate a solenoid fault from worn packs.
This kit is listed for the 2003 and later 4T65E with the pawl-type input clutch, and the listing states it does not fit Volvo applications. Because the change happened during the 2003 model year transition, a car titled as a 2003 can still be found with sprag-type parts after earlier repairs. Count the teeth on an old input friction: 30 teeth matches this kit, 32 means you need the 1997-2002 4T65E clutch module. Transmission Digest warns never to mix pawl and sprag parts. Send us your year and VIN if you want a second check, and see every part for this transaxle on the 4T65E parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Count the teeth on an old input clutch friction. The 2003-up pawl design uses a 30-tooth friction; the earlier sprag design uses 32. Send us your VIN if you are unsure.
Not as supplied, because the input frictions are made for the 30-spline pawl clutch. Use the 1997-2002 module unless the unit was converted to the complete pawl-clutch set.
It is assembled from BorgWarner, Raybestos, Allomatic or Alto stock depending on availability, always as one complete kit for this application.
Gaskets and piston seals, the filter, heat-marked steels and any worn waved plates. Check the 4th clutch hub spline and the channel plate AFL valve bore too.
Yes. Clear the stored adapts and drive through a full set of shifts so the computer can learn the new clutch fill times.
Dexron VI. GM specifies it for the 4T65E in later owner manuals, and it replaces the Dexron III these cars were first filled with. Check the level hot.
