P0700 on Lincoln
Transmission Control System Malfunction
P0700 on Lincoln vehicles indicates transmission control system malfunction. Au7o has documented this code across 1 Lincoln model — most commonly on Aviator. P0700 is a general code indicating the transmission control module (TCM) has detected a fault somewhere in the transmission control system and has requested the check engine light be turned on. By itself it doesn't pinpoint the problem — it's an 'umbrella' code that tells you to look for additional, more specific transmission codes stored alongside it. The actual fault could be electrical, a sensor, a solenoid, or an internal transmission issue. You may notice harsh or delayed shifts, slipping, or the transmission going into a protective 'limp' mode.
Common Causes of P0700
- •Stored companion transmission codes pointing to the real fault
- •Faulty shift solenoid or pressure control solenoid
- •Low, dirty, or degraded transmission fluid
- •Faulty transmission speed or input/output sensor
- •Wiring, connector, or ground problems at the transmission
- •Failing transmission control module (TCM)
- •Internal transmission mechanical wear or clutch problems
- •Valve body fault or sticking valves
P0700 on Lincoln by Model
Lincoln Aviator(1 issue)
- 10R80 Automatic Transmission Loose Bolt / Park Failure2022-2025
The Ford 10R80 10-speed automatic transmission used in the Aviator can have a loose or missing park pawl/output bolt that prevents the transmission from securely engaging Park. If the vehicle is not held by Park, it can roll away even with the shifter in Park, creating a crash and injury risk. This was serious enough to trigger a federal recall covering 2022-2023 Aviators, and a separate 2025 recall addressed incorrect main control valve bodies causing reverse-gear failure or unexpected forward movement.

What does P0700 mean on Lincoln?▼
P0700 stands for "Transmission Control System Malfunction." P0700 is a general code indicating the transmission control module (TCM) has detected a fault somewhere in the transmission control system and has requested the check engine light be turned on. By itself it doesn't pinpoint the problem — it's an 'umbrella' code that tells you to look for additional, more specific transmission codes stored alongside it. The actual fault could be electrical, a sensor, a solenoid, or an internal transmission issue. You may notice harsh or delayed shifts, slipping, or the transmission going into a protective 'limp' mode. On Lincoln specifically, this code is documented across 1 model.
What causes P0700 on Lincoln vehicles?▼
Common causes on Lincoln: Stored companion transmission codes pointing to the real fault, Faulty shift solenoid or pressure control solenoid, Low, dirty, or degraded transmission fluid, Faulty transmission speed or input/output sensor, Wiring, connector, or ground problems at the transmission.
