Page language: EN

Causes

  • Faulty torque converter clutch (TCC) solenoid or pressure control valve
  • Open, shorted, or corroded wiring/connectors in TCC circuit
  • Poor ground or low battery/charging voltage
  • Low, contaminated, or incorrect automatic transmission fluid (ATF) level
  • Internal transmission hydraulic or mechanical failure (worn clutch, valve body)
  • PCM/TCM software or internal fault

Symptoms

  • Malfunction Indicator Lamp (MIL) illuminated
  • Reduced fuel economy (TCC not locking up)
  • Higher than normal engine RPM at highway speeds
  • Transmission slipping, delayed or harsh engagement
  • Shudder or vibration during attempted lockup
  • Transmission temperature higher than normal

What to check

  • Read and record freeze frame and full DTC list with a scan tool
  • Check live data: TCC commanded state, TCC actual state, duty cycle, line pressure, vehicle speed, engine RPM
  • Inspect TCC solenoid connector and wiring for corrosion, damage, pin push-out or chafing
  • Measure solenoid resistance per manufacturer spec
  • Verify battery and charging system voltage under load
  • Check ATF level, condition, odor and color; inspect for metal or debris

Signal parameters

  • TCC commanded signal (ON/OFF or duty cycle %)
  • TCC actual/feedback (ON/OFF or apply pressure reading if available)
  • TCC solenoid resistance (ohms) — compare to spec
  • Battery/charging voltage (12–14.5 V)
  • Transmission line pressure (psi) — varies by application
  • Engine RPM and vehicle speed during lockup command

Diagnostic algorithm

  1. Retrieve freeze frame and scan tool data; note when code set (speed, RPM, temp).
  2. Verify ATF level and condition; top or change fluid if low/contaminated and retest.
  3. Visually inspect TCC solenoid harness and connector; repair any damaged wiring and ensure good pin contact.
  4. Disconnect TCC solenoid and measure resistance; compare to spec. If out of range, replace solenoid.
  5. With ignition on, backprobe solenoid connector and verify proper reference voltage and ground/PCM control signal (duty cycle or switched 12V) while commanding TCC on with a scan tool.
  6. Check for shorts to power or ground and for high resistance circuits; wiggle test wiring while monitoring live data for intermittent faults.
  7. If electrical side tests good, check transmission line pressure and perform a stall/drive test per service manual to verify mechanical apply of torque converter clutch.
  8. If hydraulic/mechanical problems are suspected (low pressure, internal leaks, clutch wear), consider valve body/service or transmission rebuild and consult service information/TSBs.
  9. Clear codes and test drive to confirm repair. If code returns, further module-level diagnostics or replacement (PCM/TCM) may be required after confirming wiring and mechanical integrity.

Likely causes

  • Failed TCC solenoid (stuck or electrically faulty)
  • Broken wire or poor pin connection at solenoid connector
  • Low line pressure preventing clutch apply (worn pump or leaks)
  • Contaminated ATF causing valve sticking
  • PCM/TCM not commanding or not sensing TCC correctly

Fault status

⚠️ Status
PCM/TCM reports Torque Converter Clutch Circuit Performance - clutch commanded but not performing as expected (stuck off). Monitor/inspect TCC solenoid, wiring, fluid and transmission hydraulic function.
🟡 Repair difficulty: Medium
⏱️ Diagnostic time: 1.0-3.0 hours

  5. With ignition on, backprobe solenoid connector and verify proper reference voltage and ground/PCM control signal (duty cycle or switched 12V) while commanding TCC on with a scan tool.
  6. Check for shorts to power or ground and for high resistance circuits; wiggle test wiring while monitoring live data for intermittent faults.
  7. If electrical side tests good, check transmission line pressure and perform a stall/drive test per service manual to verify mechanical apply of torque converter clutch.
  8. If hydraulic/mechanical problems are suspected (low pressure, internal leaks, clutch wear), consider valve body/service or transmission rebuild and consult service information/TSBs.
  9. Clear codes and test drive to confirm repair. If code returns, further module-level diagnostics or replacement (PCM/TCM) may be required after confirming wiring and mechanical integrity.

Likely causes

  • Failed TCC solenoid (stuck or electrically faulty)
  • Broken wire or poor pin connection at solenoid connector
  • Low line pressure preventing clutch apply (worn pump or leaks)
  • Contaminated ATF causing valve sticking
  • PCM/TCM not commanding or not sensing TCC correctly

Fault status

⚠️ Status
PCM/TCM reports Torque Converter Clutch Circuit Performance - clutch commanded but not performing as expected (stuck off). Monitor/inspect TCC solenoid, wiring, fluid and transmission hydraulic function.
🟡 Repair difficulty: Medium
⏱️ Diagnostic time: 1.0-3.0 hours

MERCEDES-BENZ P — Powertrain

Torque Converter Clutch Circuit Performance or Stuck Off

Brand: MERCEDES-BENZ
Type: P — Powertrain
Views: UK: 22 EN: 18 RU: 31
AI status
Completed
ready
Completed 100%
Page language: EN

Causes

  • Faulty torque converter clutch (TCC) solenoid or pressure control valve
  • Open, shorted, or corroded wiring/connectors in TCC circuit
  • Poor ground or low battery/charging voltage
  • Low, contaminated, or incorrect automatic transmission fluid (ATF) level
  • Internal transmission hydraulic or mechanical failure (worn clutch, valve body)
  • PCM/TCM software or internal fault

Symptoms

  • Malfunction Indicator Lamp (MIL) illuminated
  • Reduced fuel economy (TCC not locking up)
  • Higher than normal engine RPM at highway speeds
  • Transmission slipping, delayed or harsh engagement
  • Shudder or vibration during attempted lockup
  • Transmission temperature higher than normal

What to check

  • Read and record freeze frame and full DTC list with a scan tool
  • Check live data: TCC commanded state, TCC actual state, duty cycle, line pressure, vehicle speed, engine RPM
  • Inspect TCC solenoid connector and wiring for corrosion, damage, pin push-out or chafing
  • Measure solenoid resistance per manufacturer spec
  • Verify battery and charging system voltage under load
  • Check ATF level, condition, odor and color; inspect for metal or debris

Signal parameters

  • TCC commanded signal (ON/OFF or duty cycle %)
  • TCC actual/feedback (ON/OFF or apply pressure reading if available)
  • TCC solenoid resistance (ohms) — compare to spec
  • Battery/charging voltage (12–14.5 V)
  • Transmission line pressure (psi) — varies by application
  • Engine RPM and vehicle speed during lockup command

Diagnostic algorithm

  1. Retrieve freeze frame and scan tool data; note when code set (speed, RPM, temp).
  2. Verify ATF level and condition; top or change fluid if low/contaminated and retest.
  3. Visually inspect TCC solenoid harness and connector; repair any damaged wiring and ensure good pin contact.
  4. Disconnect TCC solenoid and measure resistance; compare to spec. If out of range, replace solenoid.
  5. With ignition on, backprobe solenoid connector and verify proper reference voltage and ground/PCM control signal (duty cycle or switched 12V) while commanding TCC on with a scan tool.
  6. Check for shorts to power or ground and for high resistance circuits; wiggle test wiring while monitoring live data for intermittent faults.
