Master overhaul kit for the Chrysler 40TE, 41TE and A604 4-speed: frictions, steels, filter, gaskets and seals to rebuild the whole unit in one box.
If your PT Cruiser, Sebring, Stratus, Cirrus or Pacifica slips on the 2-4 shift, flares into third, or drops into second gear limp mode with a gear ratio code, and the pan is full of dark fluid and clutch material, the transaxle needs a full overhaul. This master kit covers the 40TE, 41TE, A604 and F4AC1 versions of Chrysler's four-speed front-drive unit. The kit photo shows a full set of friction plates, a full set of steel plates, the pan filter, the cork pan and side cover gaskets, the pump gasket, the three valve body separator gaskets, metal-clad seals, O-rings and the sealing rings, so the clutches and the seals are both new from one box.
The 40TE, 41TE and original A604 are versions of the same Chrysler Ultradrive design. It has no bands: five clutch packs (underdrive, overdrive, reverse, 2-4 and low/reverse) do all the work, and the transmission controller applies them through solenoids and watches input and output speed to decide whether each shift happened correctly. It also keeps a clutch volume index, or CVI, for each clutch, which is a learned number for how much oil it takes to fill and apply that pack. As frictions wear and clearances open up, the CVI climbs. When a pack slips past what the controller will accept, it sets a ratio code and defaults to second gear. New frictions and steels restore the clearances, and fresh sealing rings and seals stop the circuit leaks that make a pack fill slowly in the first place.
Pull the codes and read the CVIs with a scan tool before you tear anything down. A CVI that is high on one clutch points to that pack or its feed circuit; codes with normal CVIs often point to a solenoid pack, wiring or valve body problem that a rebuild will not fix. Delayed reverse with a high low/reverse CVI can also come from a leaking low/reverse piston retainer feed, which should be checked during the teardown. Our guide 41TE / A604 Ultradrive problems explains limp mode, CVIs and the solenoid switch valve, and 41TE slipping under load covers the underdrive clutch and its oil feed.
The listing covers the 1995 Chrysler LeBaron 3.0L, 1995-2000 Cirrus 2.4L and 2.5L, 1995-2000 Sebring 2.0L and 2.4L, 2001-2008 PT Cruiser 2.0L and 2.4L, and 2004-2008 Pacifica 3.5L and 3.8L. The Ultradrive changed over its life: early A604 units, later 40TE and 41TE units, and the electronics and valve body revisions all differ in places, and the 42RLE is a different transmission. Match the transmission tag, the pan shape and the plate counts per pack to the kit, or send us your year and VIN before you order. The full lineup for this family is on our 41TE / A604 parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes, it is listed for the 40TE, 41TE, A604 and F4AC1. These units share most hard parts, but plate counts and some parts changed by year, so compare the pack counts and the transmission tag during teardown.
No. The 42RLE is a rear-wheel-drive derivative with its own case and kits. Buy a 42RLE-specific kit for a Liberty, Wrangler or Dakota.
Going by the kit photo: friction plates, steel plates, the pan filter, pan and side cover gaskets, the pump gasket, three valve body separator gaskets, seals, O-rings and sealing rings. Pistons, bushings and hard parts are not included.
ATF+4. Soak the new frictions in it before assembly and do not mix in other fluids; the wrong fluid causes shudder and shift complaints in these units.
The controller stores a clutch volume index for each clutch from the worn unit. Without a quick learn, it uses the old values and shifts harshly or flares until it relearns. A scan tool that supports Chrysler quick learn does it in a few minutes.
