P0740 on Jeep
Torque Converter Clutch Circuit Malfunction
P0740 on Jeep vehicles indicates torque converter clutch circuit malfunction. Au7o has documented this code across 2 Jeep models — most commonly on Compass, Patriot. 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 Jeep range from $200 to $5,000, 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 Jeep by Model
Jeep Compass(1 issue)
- Jatco CVT Transmission Failure / Overheating2007-2017
First-generation Compass models (2007-2017) equipped with the Jatco CVT2 continuously variable transmission suffer from overheating, slipping, shuddering, and premature failure. The CVT fluid breaks down under heat stress, causing the pulleys to wear and the belt to slip. Overheating is especially common in hot weather, stop-and-go traffic, or when towing. "Transmission Over Temp" warnings are extremely common.
Jeep Patriot(1 issue)
- Jatco CVT Transmission Overheating / Failure2007-2014
The Jatco CVT2 continuously variable transmission is the single biggest reliability problem on the Patriot. The CVT overheats frequently, especially in hot weather, stop-and-go traffic, or on hills. When the fluid breaks down from heat, the pulleys wear and the steel belt slips, leading to complete transmission failure. "Transmission Over Temp" and limp mode are extremely common complaints. In 2014, Jeep dropped the CVT in favor of a 6-speed automatic on most trims.
