P2736
Pressure Control Solenoid F ElectricalP2736 is a generic OBD-II powertrain diagnostic trouble code: Pressure Control Solenoid F Electrical. It is logged by the engine control unit when the powertrain monitor detects that a specific fault threshold has been exceeded — typically resulting in the malfunction-indicator lamp (MIL / check-engine light) being illuminated.
What P2736 means
P2736 is set when the TCM (Transmission Control Module) or PCM detects an electrical fault in the control circuit for Pressure Control Solenoid F. Pressure control solenoids regulate hydraulic pressure within the automatic transmission valve body to achieve precise clutch and band engagement. Solenoid F typically governs a specific clutch pack or hydraulic circuit; the exact clutch association varies by transmission design and manufacturer.
An electrical fault may be an open circuit in the solenoid winding or connecting harness, a short to ground or to voltage on the control wire, or a failed driver stage within the TCM. The module typically diagnoses the fault by monitoring the current through the solenoid and comparing it with the commanded duty cycle. Any significant deviation triggers the electrical fault code.
Depending on which clutch circuit Solenoid F governs in the specific transmission, the driveability impact can range from intermittent harsh shifts to a complete loss of certain gear ratios and forced entry into a limp-home mode that restricts the transmission to a single forward gear. Transmission fluid condition and level should be checked before electrical diagnosis as contaminated or degraded fluid can cause solenoid sticking that mimics electrical faults.
Common causes
Most-frequently reported root causes when P2736 is logged.
-
1
Open circuit in the Pressure Control Solenoid F winding.
-
2
Short to ground or short to voltage on the solenoid control wire.
-
3
Corroded or damaged transmission wiring harness connector inside or outside the transmission.
-
4
Failed TCM internal driver for the Solenoid F control channel.
-
5
Transmission fluid contamination causing solenoid valve sticking and overcurrent.
-
6
Solenoid F body damage from debris in degraded transmission fluid.
-
7
Wiring chafing inside the transmission oil pan or at the case exit grommet.

How to diagnose P2736
A typical diagnostic flow when this code is present.
-
1
Connect a scan tool and read all stored TCM DTCs and freeze-frame data, noting transmission temperature and gear at fault occurrence.
-
2
Check transmission fluid level and condition; dark, burnt-smelling, or metallic fluid should be addressed before electrical diagnosis.
-
3
Access the external transmission harness connector and measure Solenoid F winding resistance; compare with specification.
-
4
Check for short to ground or short to voltage on the Solenoid F control wire with the TCM disconnected.
-
5
Inspect the internal transmission wiring harness for damage where it routes through the valve body and exits the case.
-
6
If wiring and solenoid resistance are within specification, check for TCM supply voltage, ground, and communication integrity.
-
7
After repair, perform a transmission relearn or adaptation reset procedure as required by the manufacturer.

Frequently asked questions
Will P2736 always put the transmission in limp mode?
Not always immediately, but most calibrations will enter a reduced-function mode when a pressure control solenoid fault is active to protect the transmission from damage.
Can bad transmission fluid cause P2736?
Yes. Degraded fluid can allow debris to restrict Solenoid F, causing it to draw abnormal current and triggering the electrical fault monitor.
Is P2736 serious?
Yes. Continued driving with an active pressure control solenoid fault can accelerate clutch and friction element wear due to incorrect hydraulic pressures.
What is the difference between P2736 and a solenoid performance code?
P2736 is an electrical circuit fault (wiring, connector, driver stage). A performance code indicates the solenoid is electrically functional but not producing the expected hydraulic response.
Disabling P2736 in software
RaceTune can permanently disable P2736 — and any other OBD-II diagnostic trouble code — on every ECU family we support. The monitor is disabled inside the ECU itself, so the fault stops being logged: the warning light stays off and the engine never enters limp mode for this code. The change is tied to your exact software version.
