P0732 on Lincoln
Gear 3 Incorrect Ratio
P0732 on Lincoln vehicles indicates gear 3 incorrect ratio. Au7o has documented this code across 1 Lincoln model — most commonly on Aviator. 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 Lincoln range from $800 to $7,000, 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

Lincoln Aviator(1 issue)
- 10R60/10R80 MHT Harsh/Delayed Shifts from Sticking Valve Body and CDF Clutch Sleeve Movement2020-2023
Many 2020-2023 Aviators with the 10R60 10-speed automatic (3.0L EcoBoost) and 10R80 MHT (Grand Touring PHEV) exhibit harsh 1-2/2-3 upshifts, clunky engagements into Drive or Reverse, and delayed shifts, with or without illuminated MIL. Root cause per Ford TSB 23-2250 is software/solenoid ID strategy, sticking valves in the main control valve body, and/or axial movement of the CDF clutch cylinder sleeve. Ford issued multiple TSBs (21-2316, 22-2102, 22-2428, 23-2250, 24-2046) and a related 10R80 class action is active in 2025 for sibling Ford/Lincoln models.

What does P0732 mean on Lincoln?▼
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 Lincoln specifically, this code is documented across 1 model.
What causes P0732 on Lincoln vehicles?▼
Common causes on Lincoln: 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 Lincoln?▼
Repair costs on Lincoln range from $800 to $7,000, depending on the specific model and root cause.
