P0732 on Lincoln
Gear 3 Incorrect Ratio
P0732 on Lincoln vehicles indicates gear 3 incorrect ratio. Au7o has documented this code across 2 Lincoln models — most commonly on Aviator, Nautilus. 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.
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 Lincoln by Model
Lincoln Aviator(1 issue)
- 10R60/10R80 MHT Harsh or Delayed Engagement and Shifts (TSB 22-2428)2020-2023
Some 2020-2023 Lincoln Aviators equipped with a 10R60 and built on or before December 23, 2022, or a 10R80 MHT and built on or before August 15, 2022, may have harsh or delayed engagement and/or harsh or delayed shifts. Ford TSB 22-2428 says the condition may involve PCM/TCM software, the transmission solenoid-ID strategy, sticking main-control valves, or axial movement of the CDF clutch-cylinder sleeve. The complaint may occur with or without a malfunction indicator and the bulletin's listed transmission DTCs. The symptom alone does not select a valve body, CDF cylinder, or complete transmission.
Lincoln Nautilus(1 issue)
- 8F35 8-speed automatic shudder, buck, and jerk under 35 mph2019-2021
Nautilus models built on or before March 11, 2021 with the 8F35 8-speed automatic commonly exhibit a shudder, buck, hesitation, or jerk while accelerating from a stop up to about 35 mph (57 km/h). Ford Technical Service Bulletin 21-2389 (superseding 21-2081) attributes the condition primarily to PCM/transmission solenoid control software rather than internal mechanical wear, though severe untreated cases progressed to harsh shifting and, in a minority of CarComplaints reports, complete transmission failure. This is the single most-complained-about Nautilus problem and is the subject of a Chimicles Schwartz Kriner class-action investigation covering 2019-2021 Edge/Nautilus 8F35 vehicles.

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 2 models.
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 vary widely depending on the root cause and specific Lincoln model.
Which Lincoln models have P0732 documented?▼
Au7o has documented P0732 on 2 Lincoln models: Aviator, Nautilus.
