P0732 on Honda
Gear 3 Incorrect Ratio
P0732 on Honda vehicles indicates gear 3 incorrect ratio. Au7o has documented this code across 1 Honda model — most commonly on Passport. 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 Honda range from $1,800 to $3,800, 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 Honda by Model
Honda Passport(1 issue)
- Automatic Transmission Torque Converter Clutch Shudder and 2nd-Gear Failure2000-2002
The first-generation Passport's 4-speed automatic is widely documented for torque-converter clutch shudder, slipping, harsh shifts, and eventual hard-part failure, especially loss of 2nd gear. Honda issued service information tied to Isuzu-sourced driveline components, and owner complaints frequently describe the vehicle revving without acceleration or dropping into limp behavior after warm-up. Once clutch material contaminates the fluid, the problem often progresses quickly from intermittent shudder to a full rebuild or replacement.

What does P0732 mean on Honda?▼
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 Honda specifically, this code is documented across 1 model.
What causes P0732 on Honda vehicles?▼
Common causes on Honda: 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. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P0732 on a Honda?▼
