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 Nautilus. 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 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 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. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P0700 on a Lincoln?▼
Repair costs vary widely depending on the root cause and specific Lincoln model.
Which Lincoln models have P0700 documented?▼
Au7o has documented P0700 on 1 Lincoln model: Nautilus.
