P2764 on 2015-2022 Jeep Compass: Torque Converter Solenoid Circuit Fixes

What's Unique About the 2015-2022 Jeep COMPASS

The 2015-2022 Jeep Compass spans two distinct generations with different automatic transmissions, which is critical for diagnosing P2764. First-generation models (2015-2017) primarily use a PowerTech 6-speed automatic (6F24) or a CVT, where individual solenoid and valve body issues are common. Second-generation models (2018-2022) use a different 6-speed Aisin automatic for FWD or a ZF 9-speed (948TE) for 4x4 models. The ZF 9-speed, in particular, is known for complex electronic controls, and issues can stem from the integrated valve body/solenoid assembly or the wiring harness. While the underlying cause (TCC solenoid circuit) is the same, the specific part and repair procedure depend heavily on which transmission the vehicle has. The provided TSB #9004009 for the 62TE transmission does not apply to the Compass, as it was never equipped with this specific transmission, though the diagnostic logic can be a helpful reference.

Diagnostic Flowchart

Tap your situation to follow the diagnostic path that matches what you're seeing on this vehicle.

Generation note: Yes, this range covers two generations. The 2015-2017 models are the first generation (MK) and may have a 6-speed automatic (6F24) or a CVT. The 2017.5-2022 models are the second generation (MP) and use a 6-speed Aisin automatic (FWD) or a ZF 9-speed automatic (948TE) for 4x4 models. The diagnostic and repair process, particularly the location and type of solenoid, differs significantly between these transmissions.

Symptoms You May Notice

• Check Engine Light is on
• Vehicle shudders or vibrates, especially during moderate acceleration
• Engine stalls when coming to a stop, as if driving a manual and not using the clutch
• Transmission slips or shifts harshly
• Delayed gear engagement from a stop
• Reduced fuel economy
• Transmission may enter 'limp mode,' limiting speed
• A feeling of 'slipping' where engine RPMs rise without a proportional increase in vehicle speed

Most Likely Causes

1. Faulty Torque Converter Clutch (TCC) Solenoid 🔴 High Probability Solenoids are a common failure point in many automatic transmissions due to heat and contamination from old fluid. In the 6F24, the solenoid is a known service item. In the ZF 9-speed, the solenoids are integrated into the valve body, which has a history of electronic issues.
   How to confirm: A technician can test the solenoid's resistance with a multimeter or command it with a bi-directional scan tool to check its operation. The solenoid is typically located on the valve body inside the transmission.
   Typical fix: For the 6F24, replace the individual TCC solenoid or solenoid pack. For the ZF 9-speed, the entire valve body assembly is often replaced.
   Est. part cost: $50-$150 for a single solenoid, $300-$800 for a valve body assembly.
2. Damaged Wiring or Corroded Connectors 🟡 Medium Probability The 'Circuit Low' definition specifically points to an electrical fault. Wires leading to the transmission can be damaged by road debris or heat from the exhaust, and connectors can corrode from moisture.
   How to confirm: Visually inspect the wiring harness going to the transmission for any signs of melting, chafing, or corrosion at the main connector. Check for voltage and continuity from the TCM to the solenoid circuit using a multimeter.
   Typical fix: Repair the damaged section of the wiring harness or clean/replace the corroded connector.
   Est. part cost: $20-$100
3. Low or Contaminated Transmission Fluid 🟡 Medium Probability Old, dirty fluid can contain debris that clogs solenoid passages, causing them to stick or fail. Low fluid levels can cause a drop in hydraulic pressure, affecting solenoid operation. The ZF 9-speed is particularly sensitive to fluid type and condition.
   How to confirm: Check the transmission fluid level and condition according to the manufacturer's procedure. If the fluid is dark, burnt-smelling, or contains metallic particles, it indicates a problem.
   Typical fix: Perform a transmission fluid and filter change using the correct OEM-specified fluid (e.g., Mopar ZF 8&9 Speed ATF or Mopar SP-IV for the 6F24).
   Est. part cost: $100-$250
4. Faulty Transmission Control Module (TCM) ⚪ Low Probability While less common, the TCM itself can fail, specifically the internal driver circuit that sends voltage to the solenoid. The ZF 9-speed transmission has documented issues with its TCM and related wiring harnesses.
   How to confirm: This is typically a diagnosis of exclusion. If the solenoid, wiring, and fluid are all confirmed to be good, the TCM becomes the primary suspect.
   Typical fix: Replace and reprogram the Transmission Control Module. On some Compass models, the TCM is integrated with the valve body or located externally.
   Est. part cost: $400-$1200

Rare But Worth Checking

• Internal Torque Converter Failure: While the TSB for the 62TE transmission doesn't apply, its diagnostic logic is still relevant. If the solenoid and circuit are good, a failure within the torque converter's lock-up clutch mechanism itself can trigger this code.
• Clogged Internal Transmission Passages: Debris from normal wear can block the small fluid passages within the valve body, starving the TCC solenoid of the hydraulic pressure it needs to function. This can necessitate a valve body cleaning or replacement.

Diagnosis Steps

1. Scan the vehicle for all stored trouble codes and review freeze frame data.
2. Check the level and condition of the transmission fluid. This is a critical first step.
3. Visually inspect the transmission wiring harness and connectors for any signs of damage, corrosion, or fluid leaks.
4. Using a professional scan tool, monitor live data from the TCC solenoid circuit and command the solenoid on and off to check for a response.
5. If the solenoid doesn't respond, test the resistance of the solenoid at the transmission connector. Compare the reading to the manufacturer's specifications.
6. Check for proper voltage (typically ~12V) and ground at the transmission connector from the TCM. A reading below 9V confirms a low voltage condition.
7. If the solenoid and wiring test good, the issue may be internal to the transmission (valve body, torque converter) or a faulty TCM.

Related Codes That Often Appear With This One

• P0740 — This code also relates to the Torque Converter Clutch Circuit, indicating a general malfunction. It often appears alongside P2764.
• P0741 — This code means 'Torque Converter Clutch Circuit Performance or Stuck Off,' which is a closely related fault indicating the clutch is not engaging as commanded.
• U0402 — This code indicates 'Invalid Data Received From Transmission Control Module' and can appear with P2764 on ZF 9-speed models, pointing towards a deeper electronic or communication issue.

Technical Service Bulletins (TSBs) & Recalls

• TSB #9004009 / #9004206: While for the 62TE transmission (not in the Compass), it provides a relevant diagnostic path: if the TCC solenoid tests good, the torque converter itself is the likely failure point for codes P0740 or P2764.

Platform-Specific Known Issues

• First-Gen (2015-2017) 6F24 Transmission: These models use a PowerTech 6F24 6-speed automatic. The TCC solenoid is located on the valve body and is accessible after removing the transmission pan. It can often be replaced as an individual component or as part of a solenoid pack.
• Second-Gen (2018-2022) ZF 9-Speed (948TE) Transmission: 4x4 models use the ZF 948TE transmission, which has known complexities. The solenoids are integrated into the valve body, and a P2764 code often leads to the replacement of the entire valve body assembly. Wiring harness issues are also a potential cause.

Mechanic-Grade Diagnostic Values

• TCC Solenoid Voltage (Key On) — expected: ~12 V (+/- 0.5V). Failure: A reading below 9V confirms the 'Circuit Low' condition.
• 6F24 Transmission PWM Solenoid Resistance — expected: Approximately 5 Ohms. Failure: A significantly higher (open) or lower (short) reading indicates a faulty solenoid coil.
• 6F24 Transmission On/Off Solenoid Resistance — expected: Approximately 10 Ohms. Failure: A reading far from 10 Ohms suggests a problem with the solenoid.
• ZF 948TE Solenoid Circuit Resistance (General) — expected: 4.9 to 5.9 Ohms. Failure: A reading outside this range indicates an open or high resistance in the circuit or solenoid.
• ZF 948TE Solenoid Supply Circuit Resistance (Harness Check) — expected: Below 3.0 Ohms. Failure: Resistance above 3.0 Ohms indicates high resistance in the wiring between the TCM and the transmission assembly connector.

Scan Tool Commands That Help

• Professional OBD-II Scanner (e.g., wiTECH, ThinkDiag): Solenoid Function Test / Bidirectional Control — After verifying wiring and fluid, use this command to electronically actuate the TCC solenoid while monitoring voltage and pressure data. This helps confirm if the solenoid is mechanically stuck or electronically unresponsive, isolating the fault between the TCM, wiring, and the solenoid itself.

Wiring & Ground Locations

• G102 / G103 — On top of the transmission housing on first-generation (MK) models.. The Transmission Control Module (CVT models) and the Transmission Solenoid/Pressure Switch Assembly rely on these grounds. Corrosion or a loose connection at these points can cause intermittent low voltage issues and trigger codes like P2764.
• G100 — Located on the left front of the engine on early first-generation (MK) models.. This is a primary ground for the Powertrain Control Module (PCM). A poor connection here can cause a wide range of powertrain codes, including transmission circuit faults.
• Transmission Harness Connector — Where the main vehicle wiring harness connects to the transmission.. This is the primary interface to test the TCC solenoid circuit without opening the transmission. Technicians test for voltage, ground, and resistance at the pins of this connector to diagnose if the fault is in the wiring, the solenoid, or the TCM.

OEM Part Supersession History

• RL318224AA → 68318224AA — Part number consolidation and potential revision for the ZF 948TE valve body assembly.
  Heads up: The original part number RL318224AA is replaced by 68318224AA. When ordering, ensure the new part number is used.

Model Year Variations Within This Range

• 2015-2017: These first-generation (MK) models primarily use the 6F24 6-speed automatic, which has individual, accessible solenoids. The TCC solenoid can be tested for resistance (approx. 10 ohms for on/off type) and replaced separately from the valve body.
• 2018-2022: These second-generation (MP) models with the 4x4 ZF 9-speed (948TE) transmission have solenoids integrated into the valve body. Some aftermarket/remanufactured valve bodies are sold as a '9 solenoid' or '10 solenoid' version; it is critical to match the correct version for the specific vehicle build. The entire valve body is typically replaced as an assembly.
