P2764 on 2016-2022 Dodge Challenger: TCC Solenoid and Torque Converter Guide

What's Unique About the 2016-2022 Dodge CHALLENGER

This guide specifically addresses the Dodge Challenger models equipped with the 3.6L V6 engine and the 62TE automatic transmission. V8 models in this year range use different transmissions (typically a ZF 8-speed) where this code's causes may differ. For the 62TE transmission, a critical Technical Service Bulletin (TSB #9004009) provides a direct diagnostic path. 🎬 Watch: A breakdown of common 62TE transmission failure points. It advises that if code P2764 appears and the TCC solenoid itself tests okay, the root cause is a failed torque converter, a well-documented issue on this specific transmission. Another bulletin, ATRA #1648, notes a classic symptom of a stuck TCC solenoid is the engine stalling when put into Drive but not Reverse.

Symptoms You May Notice

• Check Engine Light is on
• Vehicle jerking or shuddering, sometimes described as driving over rumble strips, especially during light acceleration or between shifts.
• Transmission slipping or harsh, clunky shifting.
• Engine stalling or stumbling when coming to a stop after highway driving.
• Delayed engagement or poor acceleration.
• Decreased fuel economy.
• Transmission may enter "limp mode," getting stuck in one gear.
• Whining noise from the transmission, especially when cold.

Most Likely Causes

1. Failed Torque Converter 🔴 High Probability → Shop Automatic Transmission Torque Converter A manufacturer TSB (#9004009) specifically identifies this as the primary failure on the 62TE transmission when code P2764 is present and the solenoid is functional. The torque converter clutch lining is a known weak point that can burn or wear out, and the lock-up piston can crack.
   How to confirm: After confirming the TCC solenoid and its wiring are good via electrical testing, the torque converter is the diagnosed point of failure per the TSB. Drivability symptoms like shuddering and stalling that persist after solenoid checks point to the converter.
   Typical fix: Replace the torque converter. This is a labor-intensive job that requires removing the transmission. It is often recommended to flush the cooler lines and inspect the pump bushing at the same time.
   Est. part cost: $200-$600
2. Faulty Torque Converter Clutch (TCC) Solenoid / Solenoid Pack 🟡 Medium Probability → Shop Automatic Transmission Torque Converter The solenoid is an electronic component submerged in hot transmission fluid that can fail electrically or mechanically over time. The 62TE transmission is known for solenoid and valve body issues. ATRA TSB #1648 points to a defective solenoid causing stalling when shifting into Drive, a classic symptom for this code.
   How to confirm: A technician can use a scan tool to command the solenoid on/off and perform electrical tests (resistance, voltage checks) on the solenoid control circuit. The solenoid can also be tested with a multimeter for proper resistance or by applying 12V to see if it actuates.
   Typical fix: Replace the TCC solenoid or the entire solenoid pack, which is located inside the transmission oil pan or behind a side cover.
   Est. part cost: $150-$350
3. Wiring Harness or Connector Issue ⚪ Low Probability
   How to confirm: Visually inspect the wiring harness from the TCM to the transmission for any signs of damage, corrosion, or loose connections. Perform continuity and short-to-ground tests on the TCC solenoid circuit.
   Typical fix: Repair or replace the damaged section of the wiring harness or the connector.
   Est. part cost: $20-$200
4. Low or Dirty Transmission Fluid ⚪ Low Probability → Shop Transmission Assembly The 62TE can be sensitive to fluid level and condition. Burnt or debris-filled fluid can cause solenoids to stick or indicate a larger internal failure.
   How to confirm: Check the transmission fluid level and condition. The fluid should be at the correct level, pink/red in color, and not smell burnt. Dark, burnt, or debris-filled fluid indicates a problem.
   Typical fix: Perform a transmission fluid and filter change. If the fluid is heavily contaminated, it often signals a larger internal problem (like a failing torque converter).
   Est. part cost: $100-$250

Rare But Worth Checking

• Faulty Transmission Control Module (TCM): → Shop Transmission Assembly While rare, the TCM itself can fail, causing incorrect voltage signals to be sent to the solenoid. This should only be considered after all other possibilities (solenoid, converter, wiring) have been ruled out.

Diagnosis Steps

1. Verify the code with a professional OBD-II scanner.
2. Check the transmission fluid level and condition. Ensure it is clean, full, and of the correct type (Mopar ATF+4).
3. Inspect the transmission wiring harness and connectors for any visible damage, corrosion, or loose connections.
4. Using an advanced scan tool, monitor the TCC solenoid operation and check for voltage drops in the circuit. Command the solenoid on and off to check for response.
5. Perform electrical tests on the TCC solenoid circuit, checking for opens, shorts to ground, or high resistance. A multimeter can be used to check the solenoid's internal resistance.
6. If the solenoid and wiring test good, follow the guidance of TSB #9004009 and diagnose the torque converter for failure. This is the most likely cause at this point.
7. If all other components are confirmed to be working, the final step is to test the Transmission Control Module (TCM).

Parts You'll Likely Need

• Torque Converter (OEM #68004236AB) — This is the most likely cause if the TCC solenoid is functioning correctly, as per TSB #9004009. Mopar also sells complete transmission kits with a torque converter included.
  Trusted brands: Mopar, TC Remanufacturing, Pro-King, Jasper (offers remanufactured units with upgrades)
  OEM price range: $450-$800
  Aftermarket price range: $200-$500
• Transmission Solenoid Pack (OEM #5169313AA) — This part contains the TCC solenoid. An electrical failure within the solenoid itself will trigger the P2764 code. ATRA TSB #1648 specifically recommends replacing this part for a TCC stuck-on condition.
  Trusted brands: Mopar, Dorman, Rostra
  OEM price range: $250-$400
  Aftermarket price range: $150-$250
• Mopar ATF+4 Automatic Transmission Fluid (OEM #68218057AC (Quart), 68218058AC (Gallon)) — Required for any repair that involves opening the transmission, such as replacing the solenoid pack or torque converter.
  Trusted brands: Mopar, Valvoline, Castrol
  OEM price range: $10-$15 per quart
  Aftermarket price range: $8-$12 per quart

Related Codes That Often Appear With This One

• P0740 — This code for 'Torque Converter Clutch Circuit Performance or Stuck Off' is often triggered alongside P2764, as both relate to the TCC system's inability to function correctly. The TSB #9004009 explicitly mentions both codes together as pointing to torque converter failure.
• P0868 — This code for 'Transmission Fluid Pressure Low' can appear with P2764. Low fluid pressure can be a cause or a result of the TCC circuit issue, as it affects the hydraulic operation of both the solenoids and the converter.

Technical Service Bulletins (TSBs) & Recalls

• Bulletin #9004009: For 62TE equipped vehicles, if P2764 is present and the TCC solenoid is functional, the torque converter has likely failed and should be replaced.
• ATRA Bulletin #1648: Describes a scenario where a P2764 code is set and the engine stalls when put into Drive but not Reverse, caused by a mechanically stuck TCC solenoid. Recommends replacing the solenoid (Part # 5169313AA).

Platform-Specific Known Issues

• TSB #9004009 explicitly states that for vehicles with the 62TE transmission, codes P2764 or P0740 are indicative of torque converter failure if the TCC solenoid operation checks out.
• ATRA Bulletin #1648 describes a specific symptom tied to P2764 on 62TE transmissions: the engine dies when shifted into Drive, but not in Reverse. This points to a mechanically stuck TCC solenoid.
