Causes
- Faulty Transmission Control Module (TCM)
- Low or contaminated transmission fluid
- Failed shift or pressure control solenoid
- Open/shorted wiring or poor connector contacts
- Corroded grounds or low battery voltage
- Intermittent CAN bus or module communication errors
Symptoms
- Transmission enters limp/home mode or reduced shift availability
- Harsh, delayed, or no shifting
- Transmission slip or inability to engage gears
- Malfunction Indicator Lamp (MIL) / transmission warning lamp illuminated
- Stored or pending transmission-related codes
What to check
- Read and record all stored/pending transmission codes and freeze frame data with a capable scan tool
- Check battery voltage and charging system
- Visually inspect transmission fluid level, color, and smell
- Inspect wiring harness, connectors, and grounds at TCM and transmission
- Confirm CAN bus/module communication is healthy
Signal parameters
- Battery voltage at TCM: ~12–14.5 V during cranking/idle
- TCM ground continuity: near 0 Ω
- Solenoid coil resistance: typically single-digit to tens of ohms (refer to factory spec)
- Solenoid command duty cycle: 0–100% (PWM) as commanded by TCM
- Transmission line pressure: varies by gear and command, check factory spec (psi/bar)
- Transmission fluid temperature and speed sensors (input/output) readings
Diagnostic algorithm
- Use a scan tool to capture freeze frame, all transmission codes, current PID data (solenoid duty, line pressure, gear, speeds) and attempt to reproduce symptom.
- Visually inspect TCM and transmission connectors for corrosion, bent pins, or water intrusion. Repair as needed.
- Check battery and charging system; verify solid TCM power and ground circuits with meter. Repair poor connections.
- Verify CAN bus/module communication — check for bus errors and confirm other modules communicate normally.
- Check transmission fluid level and condition per manufacturer procedure (warm, on-level). If low, correct level and retest; if burnt/dark, plan fluid/ filter service.
- Measure resistance of suspect shift/pressure solenoids at the transmission connector and compare to factory specs. Wiggle-test harness while monitoring for intermittent changes.
- Perform active tests with scan tool: command solenoids and observe duty cycle, current draw, and change in line pressure/gears. If solenoid fails to respond electrically but has correct command, suspect open/short or solenoid failure.
- If electrical checks pass but hydraulic response is wrong, perform a static/dynamic transmission line pressure test per factory procedure to verify hydraulic circuit.
- If wiring and solenoids are good and line pressure is abnormal, suspect internal transmission hydraulic/mechanical issue or TCM programming/hardware fault.
- Before replacing TCM, check for available software updates and current TCM calibration. Replace TCM only after excluding wiring, power/ground, solenoid and hydraulic faults.
- Clear codes and road-test to confirm repair. Monitor for reappearance of P2714 and related codes.
Likely causes
- Damaged solenoid harness or pinched wire
- Loose or corroded TCM power/ground or connector
- Low fluid level from leak or recent service error
- Contaminated fluid causing solenoid sticking
- Faulty TCM software or internal TCM fault
Fault status
Status
Transmission control system fault detected (P2714). Possible causes: TCM error, low/contaminated fluid, shift/pressure solenoid failure, or wiring/connector/CAN communication issue. Perform electrical, fluid level, solenoid and hydraulic checks before replacing components.
Repair difficulty: Medium
Diagnostic time: 1.5-3.0 hours
