4T65E Overhaul Kit 1997-2011, new and ready to install. Fits the 4T65E. Ships fast from the USA.
This is a new ACDelco overhaul kit, part number 19258573, listed for the 1997-2011 GM 4T65E used in Chevrolet, Buick and Pontiac front-drive cars and vans: the Impala, Monte Carlo, LeSabre, Century, Lucerne, Grand Prix and their relatives. People shopping for it usually have a transaxle that is leaking from the pan or side cover, engaging late on a cold morning, or already on the bench for a drum, pump or clutch job. The listing also carries the GM numbers 24232006 (superseded) and 24240478, which helps if you are matching an old parts receipt or a dealer quote.
A 4T65E makes every gear by sending pressurized oil from the pump, through the valve body and channel plate, into a clutch piston or band servo. The oil only does its job if it stays in the circuit. Piston lip seals, drum sealing rings, O-rings and the paper and rubber gaskets between the major castings are what keep it there, and after 150,000 miles of heat they harden, shrink and leak. An overhaul kit is the full set of those soft parts. The parts catalog entry for 19258573 lists a filter, a plate, a valve, screens, O-rings, seals, gaskets and a circlip, with rubber, paper and metal gasket materials. It does not include friction plates or steels, so plan for those separately if the packs are worn.
Not every leak needs a full overhaul kit. Degrease the case, drive until the fluid is hot and look again; a single pan gasket or axle seal is a cheaper fix. If the complaint is slip or flare, pull the pan and look at the magnet and filter. Heavy friction material means the clutch packs are finished and this kit is only part of the job. Long shifts with clean fluid often trace to the pressure control circuit rather than seals, and our 4T65E pressure control solenoid guide covers how to separate the two. For a full fault-by-fault rundown, read 4T65E common problems and diagnosis.
The listing names the GM 4T65E for model years 1997 through 2011 in Chevrolet, Buick and Pontiac applications. That covers a long production run, and GM revised internal parts during it, so lay each old gasket and seal next to its replacement before you install anything; the channel plate and valve body gaskets are the ones that matter most. The heavy-duty 4T65E behind the 5.3L V8 and the Volvo version are not called out in this listing, so send us your year and VIN if your car is one of those or you are unsure. Every other part we carry for this unit is on the 4T65E parts page, and the 2000-2011 Impala-listed kit is available as the 4T65E overhaul kit 2000-2011 if that matches your car better.
After the rebuild, clear codes and let the PCM relearn shifts over several drive cycles with light, steady throttle before you judge shift quality.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The catalog entry lists a filter, plate, valve, screens, O-rings, seals, gaskets and a circlip, and specifically shows no friction plates. If the packs are worn, add frictions and steels or choose a master rebuild kit.
The listing shows GM 24232006 as the superseded number and 24240478 as another GM number for the same kit.
It is listed for the 4T65E in 1997-2011 Chevrolet, Buick and Pontiac applications. Because GM changed internal parts over that run, compare the old gaskets to the new ones and send us your year and VIN if you want fitment checked.
Dexron VI. A 4T65E Impala takes roughly 7.4 qt on a service fill per GM, and more when the converter has been drained.
If the only problem is a pan leak, yes. This kit is for a full reseal or rebuild where the castings come apart and every seal and sealing ring gets replaced.
Clear the codes and drive several cycles with gentle, steady throttle so the PCM can relearn shift adapts. A scan tool reset of the adapts, if yours supports it, speeds the process.
