P2712 on Fiat by model: symptoms, diagnosis and fix
The single-clutch automated manual offered on the Novo Uno (Dualogic on the 1.4 Fire Evo, GSR on the 1.3 Firefly 'Uno Drive') is the model's most expensive weak point. Chronic failure modes documented by Brazilian transmission specialists include worn or mis-calibrated clutch actuators causing slipping and jerky engagement, hydraulic pressure loss from leaks (pump shuts down, codes P0942/P2712), failed gear/clutch position sensors (P0805/P0806, P0715/P0725) and TCU faults that force the transmission into emergency mode or drop it into neutral while driving. It became serious enough that in 2019 Fiat recalled 11,669 vehicles across 8 models — including 916 Uno 1.3 GSR units, model years 2017-2018 (chassis 796635 to 835113) — because the transmission could shift to neutral involuntarily, causing sudden loss of drive.
Common Symptoms
- Transmission drops into neutral by itself while driving
- Jerky or delayed gear engagement
- Clutch slipping during shifts
- Reverse gear refuses to engage
- Gearbox warning light with transmission stuck in emergency mode
How to Fix
For 2017-2018 GSR cars: confirm the official recall (replacement of the gear selector sensor, ~1 hour, free) was performed. For chronic faults: scan the TCU for stored codes first; many problems are resolved by clutch actuator recalibration or replacement and hydraulic fluid/leak service rather than full transmission replacement. Worn clutches must be replaced with actuator recalibration. Use a shop experienced with Fiat Dualogic/GSR — incorrect calibration is a common cause of repeat failures.

Frequently asked questions
What does P2712 mean on a Fiat?
P2712 stands for "Pressure Control Solenoid "G" Stuck Off." P2712 indicates that the transmission's pressure control solenoid "G" is stuck in the off position, meaning the powertrain control module (PCM/TCM) detected that the solenoid is not responding to commands and hydraulic pressure for the associated clutch or circuit is not being regulated correctly. This is one of a family of generic transmission pressure-control solenoid codes and typically results in incorrect line/clutch pressure, affecting shift quality. On Fiat it is documented across 1 model: Uno.
What are the most common causes of P2712?
The most common causes of P2712 are: Faulty or mechanically stuck pressure control solenoid 'G' in the valve body, Low, dirty, or degraded transmission fluid restricting solenoid movement, Internal valve body wear, debris, or stuck spool valve, Wiring or connector faults (open, short, or corrosion) in the solenoid circuit, Internal transmission damage or worn clutch pack, Faulty TCM/PCM (less common). The specific cause varies by vehicle.
How much does it cost to fix P2712 on a Fiat?
Published repair estimates on Fiat range from $350 to $1,200 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
