P0740 on Volkswagen
Torque Converter Clutch Circuit Malfunction
P0740 on Volkswagen vehicles indicates torque converter clutch circuit malfunction. Au7o has documented this code across 1 Volkswagen model — most commonly on Routan. 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 Volkswagen range from $200 to $3,500, 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

Volkswagen Routan(1 issue)
- Transmission Shudder and 'Routan Shake'2009-2014
Routan owners widely report a characteristic shudder during acceleration and at cruising speeds, referred to as the 'Routan shake' even by VW engineers. The 62TE 6-speed automatic transmission (shared with Chrysler) develops torque converter shudder and rough shifts. Some owners have had multiple transmission replacements that still exhibit the problem. The transmission's torque converter lockup clutch is particularly prone to shudder during light-throttle cruising.
