P0740 on Volkswagen by model: symptoms, diagnosis and fix
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.
Common Symptoms
- Shuddering during light acceleration
- Vibration at 35-50 mph cruise speed
- Rough or harsh gear changes
- Hesitation when accelerating from a stop
- Slipping sensation between gears
How to Fix
Try a complete transmission fluid and filter change using ATF+4 fluid — this resolves shudder in many cases. If shudder persists, the torque converter may need replacement. Some owners report improvement with a transmission adaptation reset (done with a scan tool). In severe cases, a remanufactured transmission ($2,000-$3,500) may be necessary. Ensure any work uses Chrysler/Mopar ATF+4 fluid, not generic ATF.

Owner tips & cautions
- TipUse ONLY Mopar ATF+4 fluid — the 62TE transmission is very sensitive to fluid type and generic ATF will make problems worse.
- TipA full fluid and filter change ($250-$400) resolves the shudder in about 60% of cases — try this before replacing the torque converter.

Frequently asked questions
What does P0740 mean on a Volkswagen?
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 Volkswagen it is documented across 1 model: Routan.

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.
