P0700 on Mitsubishi
Transmission Control System Malfunction
P0700 on Mitsubishi vehicles indicates transmission control system malfunction. Au7o has documented this code across 5 Mitsubishi models — most commonly on Eclipse, Endeavor, Galant. 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. Typical repair costs on Mitsubishi range from $1,500 to $7,000, depending on the specific model and root cause.
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 Mitsubishi by Model
Mitsubishi Eclipse(1 issue)
- Automatic Transmission Failure (4-Speed)2000-2005
The 4-speed automatic transmission in the 3rd generation Eclipse (particularly V6 GT models) is prone to premature failure. The transmission develops harsh shifting, slipping, and eventually fails completely, often due to overheating and worn clutch packs.
Mitsubishi Endeavor(1 issue)
- Automatic Transmission Harsh Shifting and Failure2004-2011
The Endeavor 4-speed automatic transmission develops harsh shifting and premature wear, often failing between 100,000 and 130,000 miles. The transmission shares components with the Galant and Eclipse platforms, inheriting their reliability weaknesses.
Mitsubishi Galant(1 issue)
- 4-Speed F4A4 / 5-Speed Sportronic Automatic Transmission Failure2004-2012
9th-gen Galant transmissions develop two distinct failure patterns: the 2.4L I4 cars use the F4A4 4-speed (torque converter clutch shudder, harsh shifts after ~100k miles) and the V6 Sport/Ralliart use the W5A51 5-speed Sportronic (3rd-gear clutch pack failure, solenoid issues). Both are repairable but expensive. Mitsubishi did not issue an extended warranty for either failure mode; the V6 5-speed failures are particularly costly due to less aftermarket support.
Mitsubishi Lancer(1 issue)
- CVT Transmission Failure (Non-Evo)2008-2017
Non-Evolution Lancer models with the CVT experience premature transmission failure, with the CVT belt and pulleys wearing out between 80,000 and 120,000 miles. The transmission develops slipping, shuddering, and eventually complete failure.
Mitsubishi Outlander(1 issue)
- CVT Transmission Premature Failure2007-2020
The Jatco CVT in the Outlander is prone to premature failure, particularly under heavy loads and in hot climates. The CVT belt and pulleys wear prematurely, leading to slipping, shuddering, and eventual complete transmission failure, often between 60,000 and 100,000 miles.

What does P0700 mean on Mitsubishi?▼
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 Mitsubishi specifically, this code is documented across 5 models.
What causes P0700 on Mitsubishi vehicles?▼
Common causes on Mitsubishi: 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 Mitsubishi?▼
Repair costs on Mitsubishi range from $1,500 to $7,000, depending on the specific model and root cause.
Which Mitsubishi models have P0700 documented?▼
Au7o has documented P0700 on 5 Mitsubishi models: Eclipse, Endeavor, Galant, Lancer, Outlander.
