P0732 on Audi
Gear 3 Incorrect Ratio
P0732 on Audi vehicles indicates gear 3 incorrect ratio. Au7o has documented this code across 2 Audi models — most commonly on 100, A4 Avant. This code means the transmission control module detected that the gear ratio in 3rd 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 3rd 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. Typical repair costs on Audi range from $300 to $6,000, depending on the specific model and root cause.
Common Causes of P0732
- •Low or dirty/degraded transmission fluid
- •Worn clutch packs or friction material in 3rd gear circuit
- •Faulty shift solenoid for 3rd gear
- •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
P0732 on Audi by Model
Audi 100(1 issue)
- Automatic Transmission Harsh Shifting1990-1994
The Audi 100/200 automatic transmission develops harsh shifting patterns and delayed engagement. The multi-plate clutches and valve body solenoids wear, particularly in higher-mileage examples.
Audi A4 Avant(1 issue)
- Multitronic CVT Transmission Failure2002-2008
The Multitronic CVT used in front-wheel drive A4 Avants is prone to premature failure of the chain, pulleys, and control unit. This transmission has a poor reliability record and is expensive to repair.

What does P0732 mean on Audi?▼
P0732 stands for "Gear 3 Incorrect Ratio." This code means the transmission control module detected that the gear ratio in 3rd 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 3rd 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 Audi specifically, this code is documented across 2 models.
