P0740 on Chrysler by model: symptoms, diagnosis and fix
The 41TE (A604 Ultradrive) four-speed automatic used behind the 3.3L and 3.8L V6 in 1996-2007 Town & Country vans is the single most-reported failure on the nameplate. Clutch material and worn friction debris circulate in the fluid, plug the small feed passages in the valve body and pump, and starve the planetary gearsets of lubrication. The result is a burned front/rear clutch pack or a shattered planetary carrier. Owners commonly report the failure preceded by a stuttering or repeated 1-2 shift, delayed forward/reverse engagement with a double bump, and limp-in (second gear only). Aggravating factors documented on the owner forums include use of generic ATF instead of Chrysler ATF+4, a missed 30k-mile fluid service, and a weak/AC-ripple-producing alternator or a bad output shaft speed sensor signal confusing the TCM. This is the 4-speed unit and is a separate story from the later 62TE 6-speed used from 2007 on.
Common Symptoms
- Repeated stutter or flare on the 1-2 shift
- Delayed engagement into Drive or Reverse with a hard bump
- Stuck in second gear (limp-in mode)
- Whine or growl that changes with road speed
- Burnt-smelling, dark ATF with clutch material in the pan
- Speedometer drops out along with the shift fault
How to Fix
There is no recall. Confirmed hard-part failure requires a rebuilt or remanufactured 41TE with an updated valve body and upgraded clutch/planetary components; a fluid-and-filter service alone will not save a unit that is already slipping. Preventively, forum consensus is a drain-and-fill with genuine ATF+4 every 30,000 miles (a pressure flush on a neglected high-mileage unit is often what pushes it over the edge), plus verifying charging-system ripple and the OSS/ISS speed sensor signals before condemning the transmission - electrical faults mimic mechanical failure on this unit.

Frequently asked questions
What does P0740 mean on a Chrysler?
P0740 stands for "Torque Converter Clutch Circuit Malfunction." This code indicates an electrical malfunction in the torque converter clutch (TCC) solenoid circuit of an automatic transmission. The torque converter clutch mechanically locks the engine to the transmission at cruising speed to improve fuel economy and reduce slippage, and it is engaged by a solenoid controlled by the transmission computer. The code sets when the computer detects an open, short, or out-of-range condition in the TCC solenoid circuit. A clutch that is commanded on but slips or won't hold sets a separate code (P0741). Common signs include the converter not locking up (higher cruise RPM and poor fuel economy), a check engine light, or stalling when coming to a stop if the clutch stays applied. On Chrysler it is documented across 1 model: Town & Country.
What are the most common causes of P0740?
The most common causes of P0740 are: Faulty torque converter clutch (TCC) solenoid, Wiring or connector fault in the TCC circuit (open or short), Transmission case connector or internal harness damage, including fluid intrusion, Internal transmission electrical short, Faulty transmission control module. The specific cause varies by vehicle.
How much does it cost to fix P0740 on a Chrysler?
Published repair estimates on Chrysler range from $2,200 to $4,500 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
