P0740 on 2015-2022 Jeep Compass: Torque Converter Clutch Failure Guide

What's Unique About the 2015-2022 Jeep COMPASS

The 2015-2022 year range covers two completely different Jeep Compass generations with different transmissions. First-generation models (2015-2017) could be equipped with a Chrysler 62TE 6-speed automatic, which is specifically cited in Technical Service Bulletin (TSB) #9004009 for torque converter failures causing the P0740 code. For these specific vehicles, the code is less likely to be a simple electrical issue and more likely a mechanical failure of the converter itself. Second-generation models (late 2017-2022) use different 6-speed Aisin or 9-speed ZF automatic transmissions, where the causes for P0740 are more typical, often starting with the TCC solenoid or fluid issues.

Diagnostic Flowchart

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

Generation note: Yes, this range spans two generations. - First Generation (MK): 2015-2017: These models may have a 6-speed Chrysler 62TE automatic transmission. The provided NHTSA TSB #9004009 directly applies to these vehicles, pointing to torque converter failure. - Second Generation (MP): 2017-2022: These models use an Aisin 6-speed automatic (FWD) or a ZF 9-speed automatic (AWD). The 62TE TSB does not apply, and diagnosis follows a more standard path, starting with fluid, wiring, and the TCC solenoid.

Symptoms You May Notice

• Check Engine Light is on
• Vehicle shudders or vibrates at highway speeds (typically 40-60 mph) when the TCC tries to engage
• Engine RPMs are higher than normal when cruising on the highway
• Noticeable decrease in fuel economy
• Harsh or delayed gear shifts
• Transmission overheating, potentially triggering a warning light
• Stalling when coming to a stop (if the clutch is stuck engaged)

Most Likely Causes

1. Failed Torque Converter 🔴 High Probability → Shop Automatic Transmission Torque Converter For 2015-2017 models with the 62TE transmission, this is a well-documented failure pattern. TSB #9004009 explicitly states that if the TCC solenoid tests okay, the torque converter is the cause. Mechanics with experience on this transmission report that in nearly 100% of P0740 cases, the converter is the true culprit due to worn internal clutch material.
   How to confirm: A technician uses a scan tool to monitor TCC slip RPM. When the TCC is commanded to lock, if the slip RPM remains high (e.g., over 100 RPM) and the solenoid circuit is verified to be working, the converter is condemned.
   Typical fix: Replace the torque converter. This requires removing the transmission. 🎬 See this walkthrough of a 62TE torque converter replacement. Many technicians also recommend replacing the front pump and seals at the same time.
   Est. part cost: $200-$500
2. Faulty Torque Converter Clutch (TCC) Solenoid 🔴 High Probability → Shop Automatic Transmission Torque Converter This is the primary electrical component that controls the TCC. It's a common failure point for this code across all automatic transmissions, and the first component to check per TSB #9004009. On 2018-2022 models, this is a more likely cause than on the 62TE-equipped models.
   How to confirm: A technician can test the solenoid's resistance with a multimeter to see if it's within the manufacturer's specification. For the 62TE, the TCC solenoid is a Variable Force Solenoid and may not have a simple resistance spec, but other solenoids in the pack can be checked for consistency (1.6-1.8 Ohms). A professional scan tool can also command the solenoid on and off to check its response.
   Typical fix: Replace the TCC solenoid. This is usually located inside the transmission oil pan, attached to the valve body. 🎬 Watch: How to replace the solenoid pack on a 62TE transmission.
   Est. part cost: $50-$150
3. Low or Dirty Transmission Fluid 🟡 Medium Probability → Shop Transmission Assembly The 62TE is known to be sensitive to fluid type and condition. Using fluid other than the specified Mopar ATF+4 can cause issues. Burnt or contaminated fluid can clog solenoid passages and cause operational problems.
   How to confirm: Check the transmission fluid level and condition. Fluid should be at the correct level, pink/red in color, and not smell burnt. Dark, burnt fluid indicates excessive heat and clutch material breakdown.
   Typical fix: Perform a transmission fluid and filter change. If the fluid is very dirty, this may be a temporary fix for a larger internal problem. Some owners report multiple drain-and-fills are needed to resolve symptoms.
   Est. part cost: $50-$150
4. Damaged Wiring or Connectors ⚪ Low Probability
   How to confirm: Visually inspect the transmission wiring harness for any signs of damage, corrosion, or loose connections from the TCM to the transmission case connector. Check for continuity and shorts to ground using a multimeter.
   Typical fix: Repair or replace the damaged section of the wiring harness.
   Est. part cost: $20-$100

Rare But Worth Checking

• Faulty Transmission Control Module (TCM): → Shop Transmission Assembly While rare, the TCM itself can fail or have software glitches, sending improper signals or misinterpreting data. This is usually considered after all other possibilities have been exhausted.
• Clogged Transmission Cooler or Lines: → Shop Transmission Assembly If the transmission has overheated or a previous failure contaminated the system, debris can clog the cooler and its lines. This restricts flow and can cause pressure issues leading to TCC problems. It's standard practice to flush or replace the cooler when replacing a torque converter.

Diagnosis Steps

1. Check and verify the transmission fluid level and condition. Ensure the correct fluid type is being used (e.g., Mopar ATF+4 for 62TE). Address if low or dirty.
2. Use an OBD-II scanner to confirm P0740 and check for any other related codes like P0700 or P2764.
3. With a professional scan tool, perform a road test and monitor the 'TCC Slip Speed' or 'Torque Converter Slip' data PID. When the TCC is commanded to lock (usually at steady cruising speed above 40 mph), this value should drop to near zero (under 50-60 RPM).
4. If significant slip (e.g., >100 RPM) is observed while the TCC is commanded on, the problem is confirmed to be hydraulic or mechanical slip.
5. If the code sets immediately upon clearing, even without driving, this points towards an electrical circuit fault (open or short).
6. Inspect the transmission wiring harness for visible damage, corrosion, or loose pins at the main connector.
7. Test the TCC solenoid and solenoid pack wiring. For the 62TE, this involves checking resistance values at the main transmission connector. See 'Specific Diagnostic Values' for pinouts and specs.
8. If the solenoid and wiring test good, but the slip condition persists, the problem is internal. For 2015-2017 models with the 62TE transmission, this strongly points to a failed torque converter per TSB #9004009.
9. For 2018-2022 models, further diagnosis of the valve body or internal hydraulic circuits may be needed before condemning the torque converter.

Parts You'll Likely Need

• Torque Converter (OEM #68039261AC (example for some 62TE applications, verify by VIN)) — The most common cause of P0740 on 2015-2017 models with the 62TE transmission, as documented by a manufacturer TSB.
  Trusted brands: Mopar, LuK, Transtar, Recon
  OEM price range: $400-$600
  Aftermarket price range: $150-$400
• Torque Converter Clutch (TCC) Solenoid (OEM #5169313AA (Variable Force Solenoid for 62TE, verify by VIN)) — This is the primary control component for the TCC and a common failure point for this code, especially on 2018-2022 models. Also called a Variable Force Solenoid (VFS).
  Trusted brands: Mopar, Rostra, Dorman
  OEM price range: $100-$200
  Aftermarket price range: $40-$90
• Automatic Transmission Fluid (OEM #68218057AC (Mopar ATF+4, for 62TE)) — Fluid must be replaced when dropping the pan to service the solenoid or when replacing the transmission/torque converter. The correct type (e.g., Mopar ATF+4 for 62TE, Mopar ZF 8&9 Speed ATF for 9-speed) is critical.

Related Codes That Often Appear With This One

• P0700 — P0700 is a generic code that simply means the Transmission Control Module (TCM) has stored a fault code. It will almost always appear alongside a specific transmission code like P0740.
• P2764 — This code is also for the Torque Converter Clutch Pressure Control Solenoid Circuit and is mentioned alongside P0740 in TSB #9004009 as an indicator of potential torque converter failure.

Technical Service Bulletins (TSBs) & Recalls

• Bulletin #9004009: For 62TE equipped vehicles, P0740 with jerking or slipping indicates a torque converter failure if the TCC solenoid operation is confirmed to be okay.

Platform-Specific Known Issues

• A manufacturer Technical Service Bulletin (TSB #9004009) exists for vehicles with the 62TE transmission (found in 2015-2017 Compass models). It states that if the vehicle jerks or slips with code P0740 or P2764 and the TCC solenoid is confirmed to be working properly, the issue is a failed torque converter.
• There is a strong consensus among independent mechanics and in owner forums that for the 62TE transmission, P0740 almost always means the torque converter has failed internally and replacing the solenoid is a waste of time and money.

Mechanic-Grade Diagnostic Values

• 62TE Shift Solenoid Resistance (Low/Reverse, 2/4, Underdrive, Overdrive, DC) — expected: 1.6 - 1.8 Ohms at approx. 70°F. Consistency between solenoids is key.. Failure: A reading that is significantly higher (e.g., over 4 Ohms), lower, or open indicates a failed solenoid in the pack.
• 62TE Line Pressure Solenoid Resistance — expected: 4.8 - 5.1 Ohms.. Failure: A reading significantly outside this range (e.g., over 6.5 Ohms) suggests a fault.
• 62TE Pressure Signal Resistance (OD, 2/4, DC, Low/Reverse, LC) — expected: Approx. 300 Ohms.. Failure: An open or shorted reading.
• Scan Tool Live Data: TCC Slip Speed — expected: Near 0 RPM when TCC is commanded to lock.. Failure: A consistent reading over 100 RPM while the TCC is commanded on indicates a mechanical or hydraulic slip.

Scan Tool Commands That Help

• Professional Scan Tool (e.g., Autel, Snap-on, wiTECH): Quick Learn / Transmission Adaptation Reset — This function should be performed after replacing the torque converter, valve body, solenoid pack, or the entire transmission. It clears the old adaptive shift data from the TCM and forces it to relearn shift points and clutch apply pressures with the new components, which can resolve harsh or incorrect shifting.

Wiring & Ground Locations

• 62TE Main Transmission Connector (Solenoid Pack) — On the front of the transmission, accessible after removing components like the air cleaner body and sometimes the washer reservoir.. This connector allows for testing of all internal transmission solenoids without removing the oil pan. Pin 10 is the common power feed from the relay. By measuring resistance between Pin 10 and the specific solenoid's pin, you can diagnose an electrical fault in the solenoid pack. For example, the Low/Reverse solenoid is between Pin 10 and Pin 2.

Real Owner Repair Stories

• Forum user on chryslerminivan.net (2008 Chrysler Town & Country with 62TE transmission (same transmission as 2015-2017 Compass)) — Check Engine Light with codes P0740 and P0868 (Transmission Line Pressure Low).
  ❌ Tried (didn't work) Replacing the torque converter.
  ✅ What actually fixed it The root cause was a worn-out front pump housing bushing. This internal wear created a hydraulic leak, which prevented the TCC from engaging properly and also caused the low line pressure code. Replacing the front pump assembly resolved both issues.
