P0700 on Mazda
Transmission Control System Malfunction
P0700 on Mazda vehicles indicates transmission control system malfunction. Au7o has documented this code across 6 Mazda models — most commonly on CX-60, CX-90, Mazda2. 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 Mazda range from $300 to $3,000, 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 Mazda by Model
Mazda CX-60(1 issue)
- PHEV 8-Speed Transmission Surging, Jerking, and Gear Confusion2022-2024
The Mazda CX-60 PHEV's 8-speed automatic transmission exhibits harsh jerking, surging, and gear hunting behavior, particularly during low-speed driving, hill climbing, and transitions between electric and combustion power. The transmission appears confused during the handoff between the electric motor and the 2.5L inline-four engine, causing lurching when the driver eases off the throttle uphill. Mazda issued recall AR058A addressing PCM, BECM, TCM, and DASH-ESU software updates to improve powertrain coordination.
Mazda CX-90(1 issue)
- 8-Speed Automatic Transmission Jerkiness2024-2025
The new Aisin-sourced 8-speed automatic transmission in the CX-90 exhibits jerky low-speed shifts, particularly the 1-2 and 2-3 upshifts. The transmission hesitates during parking lot maneuvers and light throttle driving. This is Mazda's first use of this 8-speed longitudinal gearbox, and early calibration has been rough. Multiple TSBs and software updates have been released.
Mazda Mazda2(1 issue)
- TCM Reprogram Needed for Shift Quality2011-2014
The Mazda2 4-speed automatic transmission may exhibit harsh shifting, particularly the 1-2 and 2-3 upshifts during light throttle driving. Mazda released a TCM (Transmission Control Module) software update to improve shift quality and smoothness. The update adjusts shift timing and torque converter lockup strategy. This is a minor issue that does not indicate mechanical failure, and the manual transmission version is not affected.
Mazda Mazda3(1 issue)
- Clutch Judder on SkyActiv Manual Transmission2014-2025
SkyActiv-equipped Mazda3 models with manual transmission suffer from clutch judder during engagement, particularly from a stop or slow roll. The dual-mass flywheel and clutch disc material contribute to vibration felt through the pedal and drivetrain. Mazda released TSB 05-004/17 addressing clutch disc and pressure plate replacement.
Mazda Mazda6(1 issue)
- Clutch Judder on SkyActiv Manual Transmission2014-2021
Manual transmission Mazda6 SkyActiv models experience clutch judder similar to the Mazda3 issue. The dual-mass flywheel and clutch disc friction material cause shuddering during engagement, especially from a stop. Mazda acknowledged the issue via technical service bulletin.
Mazda MPV(1 issue)
- Automatic Transmission Shudder and Failure2000-2007
Automatic transmission develops torque converter shudder and eventual internal failure. Shifts become harsh and delayed. Common on 2000+ models with the 5-speed auto.

What does P0700 mean on Mazda?▼
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 Mazda specifically, this code is documented across 6 models.
What causes P0700 on Mazda vehicles?▼
Common causes on Mazda: 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 Mazda?▼
Repair costs on Mazda range from $300 to $3,000, depending on the specific model and root cause.
Which Mazda models have P0700 documented?▼
Au7o has documented P0700 on 6 Mazda models: CX-60, CX-90, Mazda2, Mazda3, Mazda6, MPV.
