P2761 Code: TCC Pressure Control Solenoid Circuit/Open
P2761 Diagnosis: Prove the TCC Circuit First
The controller detected an electrical open in the TCC pressure-control solenoid path. Save the event, map the transmission, and prove the open.
P2761 means Torque Converter Clutch Pressure Control Solenoid Control Circuit/Open. The transmission controller detected an electrical path or driver-current result consistent with an open circuit.
P2761 does not prove that the solenoid, torque converter, valve body, or transmission has failed. Save the TCM event, identify the circuit by VIN, and prove the wiring before replacing internal parts.
What Does the P2761 Code Mean?
P2761 is the standardized OBD-II description for Torque Converter Clutch Pressure Control Solenoid Control Circuit/Open. The controller commands a solenoid that helps apply and release the torque converter clutch, then monitors its driver or feedback path.
Open points to missing continuity, unsuitable driver feedback, or a related control-path problem. It differs from P2762 range/performance, P2763 high, P2764 low, and a mechanical slip verdict.
GM documents one P2761 strategy using commanded current, actual duty cycle, and an intrusive driver test. Its thresholds are controller-specific.
Map the exact TCC pressure-control circuit, then prove the connector, harness, internal lead, coil, and driver.
Check shared power, grounds, controller feeds, pass-through connectors, and module-level evidence before chasing each solenoid.
Preserve command-versus-response data; an electrical open may coexist with hydraulic or mechanical consequences.
P2761 Symptoms, Severity, and Driving Safety
P2761 may be current, pending, history, or permanent, and another module may store the clearer companion fault.
The controller may use a fail-safe pressure strategy when it cannot control the TCC pressure solenoid normally.
If lockup is inhibited, converter slip can keep engine speed higher during steady driving.
These symptoms require command, slip, ratio, fluid, and mechanical evidence; P2761 alone does not explain all of them.
Some vehicles limit gear choice or torque to control heat and protect the transmission.
An intermittent terminal or conductor can set P2761 before a driver notices a shift or lockup change.
Severity follows the symptoms and active fail-safe strategy. Converter slip can create heat; fail-safe line pressure can produce harsh shifts.
Common Causes of the P2761 Code
These are ordered test branches, not failure percentages. Begin with shared electrical evidence and accessible connections; move inside the transmission and toward the controller only when measurements justify it.
Shared Voltage, Ground, or Controller-Feed Fault
Weak voltage, a poor ground, or a resistive feed can disturb several commanded outputs.
How to prove it: Review all-module codes, then load-test VIN-correct feeds and grounds.
Check firstLoose, Corroded, or Damaged Connector Terminals
Water, fluid, spread terminals, poor locks, or heat can interrupt current.
How to prove it: Inspect both sides, verify terminal tension, and load-test the circuit.
Check firstOpen or High-Resistance External Harness
Chafing, heat, road damage, or a broken conductor can open the control or feed path.
How to prove it: Isolate the circuit and test continuity, shorts, and voltage drop.
Verify directlyInternal Harness, Leadframe, or Pass-Through Fault
Relevant wiring or a connector plate may sit under the pan or inside the case.
How to prove it: Separate external and internal sections at approved connectors.
Verify directlyOpen TCC Pressure-Control Solenoid Coil or Assembly
The coil can lose continuity; serviceability and naming vary by transmission.
How to prove it: Compare de-energized measurements with temperature-correct OEM specifications.
Verify directlyTCM/PCM Driver, Connector, or Application-Specific Module Fault
A failed driver, connector, calibration, or module defect belongs late in diagnosis.
How to prove it: Prove loads and wiring, then follow VIN/build-specific tests.
Final branchRecent work changes the order. If P2761 began after transmission, valve-body, solenoid, harness, battery, module, or fluid service, inspect the disturbed connectors, pin fit, routing, grounds, part identity, and setup steps first.

How to Diagnose P2761 Code in 6 Steps
Work from stored evidence to circuit identity, shared conditions, accessible wiring, isolated internal testing, and a verified repair. Do not erase the event or unplug the transmission before saving the original data.
P2761 Quick Diagnostic Path
-
1
Save the Complete P2761 Diagnostic Event
- Record code status, all-module DTCs, freeze frame, battery voltage, temperature, gear, speed, commanded state, and a report where supported.
- Note slip, shudder, harsh shifts, overheating, limp mode, recent service, and the exact conditions when the warning appeared.
-
2
Identify the Reporting Module and Exact Circuit
- Use VIN, transmission code, controller identification, the full OEM DTC text, and the current wiring diagram.
- Locate the correct external connector, pass-through, internal harness, solenoid designation, splice, feed, and driver pin.
-
3
Triage Shared Power, Grounds, and Companion Codes
- Check battery and charging condition, controller powers/grounds, fuses, and common feeds under load.
- If several solenoid or sensor circuits are open or low, diagnose the shared path or module evidence before individual parts.
-
4
Inspect and Load-Test Accessible Wiring
- Inspect locks, seals, pin fit, fluid or water intrusion, corrosion, rub-through, heat damage, and previous repairs.
- With the circuit safely isolated, test continuity and unwanted shorts; use voltage drop or a suitable load to expose weak conductors.
-
5
Separate Internal Harness, Solenoid, and Driver Branches
- Use approved breakpoints to determine whether the open is outside or inside the transmission; compare coil values only with OEM specifications.
- Review supported command/current or duty data. Use a meter, current clamp, or scope as the procedure requires; do not back-feed a module driver.
-
6
Repair the Proven Branch and Rerun the Monitor
- Repair only the confirmed terminal, harness, pass-through, internal lead, solenoid assembly, feed, ground, or controller cause.
- Complete required setup or relearns, clear eligible codes, reproduce the original enable conditions, and confirm normal data with no return.
How to Fix P2761 and Confirm the Repair
Restore External Wiring and Terminal Integrity
Repair proven power, ground, connector, pin-fit, chafe, open, short, or voltage-drop faults with sealed, strain-relieved, transmission-safe methods.
Repair the Pass-Through or Internal Harness
Replace or repair the VIN-correct internal leadframe, connector plate, case pass-through, or harness only after the external section passes.
Replace the Proven Solenoid or Control Assembly
Follow the exact service design: the TCC pressure-control solenoid may be separate, part of a valve body, or integrated into a control assembly.
Address Controller, Feed, or Software Last
Repair controller connections or feeds, or perform validated module service/programming, only after the load and complete circuit have passed.
Scan and Circuit Diagnosis
VIN-specific quoteFailure reproduction, diagram access, connector locations, load testing, current/waveform checks, and companion-code analysis.
External Connector or Harness
VIN-specific quoteTerminal availability, harness routing, heat protection, sealed splices, connector replacement, and access time.
Internal Harness or Solenoid
VIN-specific quoteFluid service, pan or valve-body access, integrated assembly design, seals, one-time-use fasteners, and setup procedures.
Controller or Programming
VIN-specific quoteModule location, stable programming support, security access, calibration eligibility, replacement setup, and relearns.
Universal prices mislead because P2761 may need a terminal repair, internal control assembly, or rare module work. Ask for a quote naming the proven open, fluid/seals, programming, and verification.
After repair, reconnect every lock and seal, restore fluid level by the OEM procedure, save a clean report, and clear eligible codes. Reproduce the original conditions and confirm the P2761 monitor.
P2761 Differences by Transmission and OEM Strategy
The base P2761 meaning is standardized, but layout is not. The TCM may be separate or valve-body integrated; the solenoid may be separate or part of an assembly.
Longer harness runs, case connectors, splices, and shared feeds create more accessible test points before internal service.
The controller, internal wiring, and solenoid assembly may share a fluid-exposed connector or require pan/valve-body access.
A 2023 Ram bulletin shows P2761 among several circuit codes caused by a narrowly defined internal ECM issue; it is not a universal fix.
GM’s example detects an open through driver-current behavior. A Stellantis bulletin uses the same wording on certain Ram trucks but directs a build-specific ECM investigation. Confirm VIN, transmission, module, pinout, limits, and bulletin applicability.
