P0732 on Lincoln by model: symptoms, diagnosis and fix
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.
Common Symptoms
- Harsh engagement
- Delayed engagement
- Harsh shift
- Delayed shift
- Malfunction indicator with a bulletin-listed transmission DTC
How to Fix
Have a Ford/Lincoln-capable technician confirm the transmission and build date, retrieve PCM/TCM faults, and follow TSB 22-2428 in order. The bulletin begins with available PCM/TCM programming and an adaptive-learning drive cycle, then uses the stored faults and clutch behavior to select an accelerated main-control break-in routine. If the condition remains, the procedure can require main-control overhaul and, only after the bulletin's later tests fail, condition-specific internal transmission repair. Parts and coverage must be selected by VIN and the actual failed step; this record intentionally has no buy link.
Call to confirm they can assess your vehicle and perform the stated work. Search results do not confirm qualification, eligibility or coverage.
Owner tips & cautions
- TipRecord the exact shift or engagement event and ask for the PCM/TCM fault report plus the TSB decision-tree step that failed before approving internal transmission work.
- WarningDo not order a valve body or CDF part from harsh shifting alone; Ford's procedure can resolve the condition through programming, adaptive learning, or clutch cycling before parts are selected.

Frequently asked questions
What does P0732 mean on a 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 it is documented across 1 model: Aviator.
What are the most common causes of P0732?
The most common causes of P0732 are: 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. The specific cause varies by vehicle.
How much does it cost to fix P0732 on a Lincoln?
Repair costs vary widely with the root cause and Lincoln model; each issue on this page carries its own estimate where one is published.
