P0740 on Dodge
Torque Converter Clutch Circuit Malfunction
P0740 on Dodge vehicles indicates torque converter clutch circuit malfunction. Au7o has documented this code across 2 Dodge models — most commonly on Caliber, Neon. 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 Dodge range from $1,200 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
P0740 on Dodge by Model
Dodge Caliber(1 issue)
- Jatco CVT Overheating and Premature Failure2007-2012
The Jatco CVT has an inherent overheating design flaw, especially during extended highway driving. Expected CVT lifespan only ~75,000 miles. ATF aeration compounds problems. Transmission shutdown can occur during highway driving in hot weather, leaving vehicle stranded.
Dodge Neon(1 issue)
- 3-speed TorqueFlite automatic (31TH/A413) durability problems1995-1999
First-gen Neons with the optional 3-speed automatic (a TorqueFlite-family 31TH/A413 unit) are markedly less durable than the 5-speed manual. Documented failure points include a sticking governor valve (causes high-gear starts/binding), sprag/one-way-clutch failure, and clutch/band failures leading to slipping, harsh or missed shifts, dropping out of gear, and no-reverse conditions. Fluid neglect and the Neon's cooling/heat issues accelerate wear.
