P0740 on Chrysler
Torque Converter Clutch Circuit Malfunction
P0740 on Chrysler vehicles indicates torque converter clutch circuit malfunction. Au7o has documented this code across 1 Chrysler model — most commonly on Town & Country. This code indicates a malfunction in the torque converter clutch (TCC) 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 electrical problem with the clutch circuit or sees that the clutch is not engaging or holding as expected. Common signs include slipping, shuddering, poor fuel economy, or stalling when coming to a stop. Typical repair costs on Chrysler range from $2,200 to $4,500, depending on the specific model and root cause.
Common Causes of P0740
- •Faulty torque converter clutch (TCC) solenoid
- •Low or contaminated transmission fluid
- •Wiring or connector fault in the TCC circuit
- •Worn or failing torque converter
- •Valve body wear or sticking valves
- •Internal transmission electrical short
- •Faulty transmission control module

- 41TE/A604 Four-Speed Automatic Transmission Hard-Part Failure (Planetary/Clutch Pack Burnout)1996-2007
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.
