41TE Valve Body 1991, remanufactured and ready to install. Fits the 41TE. Ships fast from the USA.
A 1991 A604 — the name Chrysler used before it became the 41TE — that shifts hard between first and second, hangs in gear before engaging Drive or Reverse, or runs a converter clutch that shudders at highway speed is almost always telling you the valve body has worn out, not that the clutch packs behind it have failed. This remanufactured valve body replaces the worn unit with a bench-tested part instead of sending you chasing the fault one bore at a time, and it's built to the same A604 specification your 1991 transmission left the factory with.
The A604 was Chrysler's first electronically controlled automatic, and the valve body is where that control actually happens. Line pressure from the pump routes through the valve body's bores and spool valves to apply the underdrive, overdrive, 2-4 and reverse clutches in sequence, while the shift and pressure control solenoids mounted on the body carry out the commands the computer sends. When the bores wear or a solenoid sticks, pressure leaks past the parts it should be sealing and the computer can no longer apply a clutch cleanly — the result is the harsh, delayed or slipping shifts these early units are known for.
Don't swap a valve body on a guess. Pull codes first and read the stored Clutch Volume Index values if your scan tool supports them — a high CVI on a specific clutch points at that clutch pack, not the valve body, while solenoid or pressure codes with normal CVIs point at the valve body or its solenoids. Our 41TE / A604 Ultradrive problems guide walks through the limp-mode and CVI diagnosis in detail, and the 41TE slipping under load guide covers the pressure and clutch-wear checks that rule out a valve body issue versus a worn clutch.
This valve body fits the 1991 A604 as built that model year. The A604/41TE ran across several internal updates even within a single model year, so match the casting number, solenoid connector, and any part number stamped on your old unit before ordering, or send us your year, make, model and VIN and we'll confirm the right version. See every 41TE part we stock on the 41TE parts page.
Drop the pan and change the fluid and filter at the same time — debris from the old valve body circulating through a fresh one is a common cause of early failure, and a A604/41TE filter kit is cheap insurance against that. Check the pump for wear while the pan is down; a worn 41TE pump starves the valve body of pressure and will make a good valve body look bad. Torque the valve body bolts in sequence to spec, refill with ATF+4 only, and run the transmission through several full shift cycles so the adaptive controller relearns against the new part before you call the job finished.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. Chrysler called it the A604 when it launched this transaxle in 1989; the name changed to 41TE later in the production run, but the transmission and its valve body design are the same family.
The A604/41TE ran in Chrysler, Dodge and Plymouth minivans and front-wheel-drive sedans of that era, and later in cars like the Stratus/Sebring and the related Jeep Liberty 42RLE. Confirm your specific application against the casting number or your VIN, since fitment changed year to year.
ATF+4 only. Using the wrong fluid is one of the fastest ways to put a new valve body right back into failure.
Pull the stored Clutch Volume Index values before replacing parts. A high CVI on one clutch points at that clutch; solenoid, pressure, or ratio codes with normal CVIs point at the valve body.
Service the filter and fluid together so debris from the old unit doesn't contaminate the new one, and check the pump while the pan is down since a worn pump starves the valve body of pressure.
If the shudder is caused by a worn TCC solenoid circuit in the valve body, yes. If it's caused by degraded fluid or a failing converter itself, a new valve body alone won't resolve it, so rule those out first.
