P0732 on Volkswagen by model: symptoms, diagnosis and fix
The 6-speed automatic transmission fitted to the V8 (the W12 uses a 5-speed automatic) develops harsh shifts and delayed engagement due to valve body wear. The transmission fluid must be serviced on schedule; neglect accelerates wear dramatically. Some units require valve body replacement by 80,000 miles.
Common Symptoms
- Harsh 2-3 shift
- Delayed engagement
- Slipping
- Transmission warning on dash
- Shuddering at low speeds
How to Fix
Service the transmission fluid and filter. If shifting is still harsh, the valve body may need replacement or reconditioning. A full transmission rebuild may be needed in severe cases.

Frequently asked questions
What does P0732 mean on a Volkswagen?
P0732 stands for "Gear 2 Incorrect Ratio." This code means the transmission control module detected that the gear ratio in 2nd gear does not match what it expects when the transmission is commanded into that gear. The computer compares input (turbine) speed to output shaft speed; if the math for 2nd gear is wrong, it sets this code. It usually points to internal slipping or a hydraulic/electronic control fault rather than a sensor reading error. On Volkswagen it is documented across 1 model: Phaeton.
What are the most common causes of P0732?
The most common causes of P0732 are: Low or dirty/degraded transmission fluid, Worn or slipping friction element (clutch or band) that holds 2nd gear, Faulty shift solenoid, Valve body or pressure control problems, Internal mechanical wear or damage in the transmission, Clogged transmission filter restricting flow, Faulty input/output speed sensor giving skewed data. The specific cause varies by vehicle.
How much does it cost to fix P0732 on a Volkswagen?
Published repair estimates on Volkswagen range from $500 to $3,000 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.
