P0740 on Dodge by model: symptoms, diagnosis and fix
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.
Common Symptoms
- Transmission overheating warning light
- Transmission shutdown during highway driving
- Slipping and whining noise
- Shuddering during acceleration
- Complete loss of drive
How to Fix
Fill transmission to absolute lowest acceptable mark to reduce aeration. Check cooling fan relay (fan failure causes CVT overheating). CVT fluid change every 30,000 miles using Mopar CVTF+4 (NOT ATF+4). Consider adding external CVT cooler for highway driving.

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.
Common Symptoms
- Slipping or flaring shifts
- Harsh or skipped shifts
- Starts moving in high gear (sticking governor)
- No reverse / stuck in gear
- Drops out of gear at speed
- Whine or lockup then failure
How to Fix
Service with correct ATF and filter on a strict interval; a governor pressure/bracket-and-spring kit (e.g., Sonnax) addresses the sticking-governor high-gear-start complaint. Slipping/no-reverse or sprag failure typically requires a rebuild or replacement transmission. Adding an auxiliary cooler helps longevity.

Frequently asked questions
What does P0740 mean on a Dodge?
P0740 stands for "Torque Converter Clutch Circuit Malfunction." 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. On Dodge it is documented across 2 models: Caliber, Neon.
What are the most common causes of P0740?
The most common causes of P0740 are: 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. The specific cause varies by vehicle.
How much does it cost to fix P0740 on a Dodge?
Published repair estimates on Dodge range from $1,200 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.
