41TE Overhaul Kit 2004, new and ready to install. Fits the 41TE. Ships fast from the USA.
A 2004 Dodge Caravan, Grand Caravan, Chrysler Town and Country, Stratus or Sebring with the 41TE automatic usually lands here for one of two reasons: it is leaking ATF+4 from the transaxle, or the clutches have let go and the whole unit is coming apart. Either way, every rubber and paper part needs replacing. This is a new 41TE overhaul kit for the 2004 model year. The product description says it contains the gaskets, seals, O-rings, sealing rings and small rubber parts needed to reseal and rebuild the transmission internals. It ships as either a Precision or a Toledo Trans-Kit (TTK) brand kit, and the photo shows the TTK version in its sealed bag. Friction plates, steels and a filter are not included.
The 41TE, first sold as the A604 Ultradrive, was one of the earliest fully electronic, clutch-to-clutch transaxles. It has no bands. The underdrive, overdrive and reverse clutches sit in the input clutch assembly, while the 2-4 and low/reverse clutches hold parts of the gearset to the case. Oil reaches the rotating input pistons across sealing rings at the reaction shaft support; the stationary clutches are fed through the case and piston retainers, sealed by gaskets and O-rings. By 2004 the 41TE was still a fixed line pressure design, so the controller relies entirely on learned clutch fill volumes to time each shift. Any seal leak raises those volumes and the shift quality falls apart. Replacing every seal at once is how a rebuilder gets the circuits back to factory tightness.
For a leak, clean the case and find exactly where the fluid starts; a gasket or seal leak is fixed by this kit alone. For shift complaints, read the codes and the clutch volume index values with a scan tool. ATRA's bulletin for the 41TE family gives the normal range for each clutch. If only one clutch reads high, that circuit is losing oil. If every clutch reads high, look at line pressure and the input clutch hub bushing first. Our 41TE slipping under load guide explains how to separate those causes, and the Ultradrive limp mode and solenoid switch valve guide covers electrical and valve body faults that can look like a seal problem.
This kit is listed for the 2004 41TE (A604). That year the 41TE was used in the Chrysler and Dodge minivans and in the Stratus and Sebring sedans, among other front-drive models. Seal kits for this family carry across many years, but case and pump details changed over the transaxle's long run, so compare your old gaskets with the new ones before installing. If you want us to check your exact application, send the year and VIN with your order. For earlier units, see the 1989-2003 41TE overhaul kit, and find every 41TE part we stock on the 41TE parts page.
If the clutches are worn, add the 41TE clutch plate set, or go to the A604 / 41TE master rebuild kit, which bundles seals with frictions and steels.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It ships as either a Precision or a Toledo Trans-Kit (TTK) overhaul kit. Both are complete gasket and seal sets for the 41TE; the photo shows the TTK bag.
No. It covers the gaskets, seals, O-rings, sealing rings and small rubber parts. Add a clutch set and a filter if the clutches are worn, or choose a master rebuild kit that includes them.
Yes. The A604 name was used when the Ultradrive was introduced, and Chrysler later renamed it 41TE. Parts listed for either name are for the same family, though details changed by year.
The kit is listed for 2004 41TE transaxles, which includes the 2004 minivans. Compare the old gaskets to the new ones as you disassemble, or send us your year and VIN before ordering so we can confirm.
Refill with ATF+4, set the level hot with the engine running, then reset the adaptives and run the quick learn with a scan tool. The controller needs to relearn the clutch volumes after a rebuild.
