P0762 on 2008-2020 Dodge Grand Caravan: Shift Solenoid 'C' Stuck On Causes and Fixes

What's Unique About the 2008-2020 Dodge Grand Caravan

The 2008-2020 Dodge Grand Caravan uses the 62TE 6-speed automatic transmission. This transmission is widely known for issues with its solenoid pack. The individual solenoids are integrated into a single block, so a failure of one solenoid, like the 'C' solenoid indicated by P0762, requires replacing the entire pack. Fortunately, this pack is located on the front/top of the transmission and can be accessed from the engine bay, making it a more straightforward repair than internal transmission work.

Symptoms You May Notice

• Check Engine Light or Transmission Warning Light is on.
• Vehicle is stuck in one gear, often called 'limp mode' (typically 2nd gear).
• Harsh, delayed, or erratic shifting between gears.
• Vehicle stalls when shifting from Reverse to Drive.
• Inability to shift into higher gears.
• Reduced fuel efficiency.
• All shift indicator lights (P, R, N, D) on the dashboard may be illuminated or boxed.
• Vehicle may seem to start in a higher gear, feeling sluggish from a stop.

Most Likely Causes

1. Failed Transmission Solenoid Pack 🔴 High Probability → Shop Transmission Assembly The 62TE transmission used in these vans has a well-documented history of solenoid pack failures. The solenoids can fail electrically (internal short/open circuit) or mechanically (stuck plunger from debris or wear).
   How to confirm: A professional bi-directional scan tool can command the solenoid and monitor its state. 🎬 See how a professional diagnoses a solenoid circuit fault. A constant 12V reading on the solenoid's circuit when it's commanded 'off' indicates a stuck-on condition. A multimeter can also be used to check the resistance of each solenoid coil at the main connector. A reading that is significantly different from other similar solenoids, or is open/shorted, confirms a failure. The P0762 code itself is a strong indicator when fluid and wiring are confirmed to be good.
   Typical fix: Replace the entire transmission solenoid pack. This part is located on the top of the transmission and is accessible after removing the battery and battery tray.
   Est. part cost: $200-$400
2. Low or Dirty Transmission Fluid 🟡 Medium Probability → Shop Transmission Assembly Low fluid levels reduce hydraulic pressure needed for proper solenoid operation. Old, contaminated fluid can contain debris that causes the solenoid plunger to physically stick. The 62TE transmission is sensitive to fluid level and condition; using anything other than Mopar ATF+4 can cause issues.
   How to confirm: Check the transmission fluid level and condition. Note: These models do not have a traditional dipstick. The level must be checked via a small capped tube (the dipstick tube), often requiring a special tool (a dipstick with markings) and a fluid temperature chart. The fluid should be at the correct level based on temperature, red in color, and not smell burnt. Dark or metallic fluid indicates a more serious internal issue.
   Typical fix: Perform a transmission fluid and filter change using only Mopar ATF+4 fluid. If the fluid is very dark or contains metal shavings, it may indicate a more severe internal transmission problem. A fluid change alone will not fix a failed solenoid pack but is a critical first step in diagnosis.
   Est. part cost: $50-$150
3. Wiring Harness or Connector Issues ⚪ Low Probability The wiring harness leading to the solenoid pack can be damaged by heat, vibration, or corrosion, causing a short to power that keeps the solenoid energized. The main connector on the solenoid pack is a common point for inspection.
   How to confirm: Visually inspect the wiring and the main 20-pin connector at the solenoid pack for any signs of damage, corrosion, or loose pins. A multimeter can be used to check for a short to power in the solenoid's control circuit between the TCM and the solenoid pack.
   Typical fix: Repair the damaged section of the wiring harness or replace the connector. In some cases, the entire engine wiring harness may need replacement if damage is extensive.
   Est. part cost: $20-$100

Rare But Worth Checking

• Faulty Powertrain Control Module (PCM) or Transmission Control Module (TCM): → Shop Engine Control Module (ECM) This is rare. The PCM/TCM is the computer that controls the transmission. A failure in the driver circuit for solenoid 'C' could cause it to be stuck on. This should only be considered after all other possibilities (solenoid, fluid, wiring) have been ruled out. On these vans, the transmission control is integrated into the PCM.

Diagnosis Steps

1. Verify the presence of the P0762 code using an OBD-II scanner. Note if P0700 is also present.
2. Check the transmission fluid level and condition. This requires an ATF temperature reading and a special dipstick tool, as there is no factory-installed dipstick. Ensure fluid is clean, red, and at the correct level per the temperature chart. Use only Mopar ATF+4 fluid.
3. Inspect the transmission wiring harness and the main connector at the solenoid pack for any visible damage, corrosion, or loose connections.
4. Use a multimeter to test the resistance of the shift solenoids at the main connector. Compare the reading for the suspect solenoid to the other identical solenoids. A significant deviation indicates a fault.
5. Use a bi-directional scan tool to monitor the commanded state and voltage of Shift Solenoid 'C'. Command the solenoid on and off. An abnormally high current draw or a constant 12V when commanded off confirms a fault.
6. If the fluid and wiring are good, and the solenoid tests bad electrically or fails the bidirectional test, the cause is a faulty solenoid pack.
7. To replace the pack, disconnect the battery. Remove the airbox, battery, and battery tray to gain access to the top of the transmission.
8. Thoroughly clean the area around the solenoid pack to prevent debris from entering the transmission.
9. Disconnect the main electrical connector from the solenoid pack.
10. Remove the bolts securing the solenoid pack (typically 8mm or 10mm bolts).
11. Carefully remove the old pack and gasket. Install the new solenoid pack with its new gasket, ensuring the surface is clean.
12. Reassemble all components, torque bolts to specification (solenoid pack bolts are typically around 105 in-lbs).
🎬 Watch: A quick walkthrough of the solenoid pack replacement process.
13. Refill transmission fluid to the correct level. This is a critical step; underfilling can cause new problems.
14. Clear the codes and perform a 'Quick Learn' adaptation procedure with a compatible scan tool. This is required for optimal shift quality.
15. Perform a road test, allowing the transmission to shift through all gears to confirm the repair.

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 be present alongside a specific transmission code like P0762.
• P0868 — This code indicates low transmission fluid pressure. It can appear alongside P0762 if the root cause is low fluid, or it can be a symptom of the internal hydraulic leak caused by the stuck solenoid itself.

Technical Service Bulletins (TSBs) & Recalls

• TSB 21-013-08: While not directly for P0762, this TSB for some Chrysler models with similar transmissions suggests a TCM software update could fix some shift quality issues before hardware replacement, highlighting the role of software in transmission behavior.
• TSB 21-008-15: This TSB applies to the 9-speed transmission, not the 62TE, and involves replacing a C-Clutch snap ring. It is not relevant to the Grand Caravan's P0762 issue.
• TSB 21-032-14 / 21-013-13: Relates to performing adaptation memory cell clearing and drive learn procedures after transmission repairs, which is a relevant procedure after replacing the solenoid pack for optimal performance.

Mechanic-Grade Diagnostic Values

• Shift Solenoid Resistance (L/R, UD, DC, 2/4, OD, LC) — expected: 1.6 - 2.0 Ohms at approx. 70°F.. Failure: A reading of infinity (open), zero (short), or a value significantly different from the other identical solenoids (e.g., 7.2 Ohms) indicates a failed coil.
• Line Pressure (VFS) Solenoid Resistance — expected: 4.8 - 5.1 Ohms at approx. 70°F.. Failure: A reading outside this specific range indicates a fault in the line pressure solenoid.
• Pressure Switch Resistance — expected: Approx. 300 Ohms.. Failure: A reading significantly different from 300 Ohms suggests a faulty pressure switch within the solenoid pack.
• Solenoid Control Circuit Voltage (Live Data) — expected: 0V or low duty cycle when commanded OFF.. Failure: A constant 12V reading on the solenoid's control circuit when it should be off confirms a 'stuck on' condition, caused by either a short to power in the wiring or a faulty PCM driver.

Scan Tool Commands That Help

• WiTech, Autel, or other professional scan tool: Quick Learn (62TE) — This procedure is required after replacing the solenoid pack, valve body, or entire transmission, or after disconnecting the battery for an extended period. It resets the transmission's adaptive learning tables to match the new components, preventing harsh shifting, and ensuring the longevity of the new parts.

Wiring & Ground Locations

• Transmission Solenoid Pack Connector (C1) — The main 23-pin round connector on the solenoid pack itself, located on the top/front of the transmission, accessible from the engine bay after removing the battery tray.. This is the primary test point for diagnosing the entire solenoid pack without removing it. Pin 10 is the common power feed from the relay. The individual solenoids are controlled by grounding their respective pins. For example, the Underdrive (UD) solenoid is on Pin 7, and the Direct Clutch (DC) solenoid is on Pin 20. Testing resistance between Pin 10 and the specific control pin identifies electrical faults in the solenoid coils.
• Engine to Chassis Ground Strap — A braided strap connecting the engine block or transaxle case to the vehicle's frame, often near the upper engine mount.. While not a direct cause, a corroded or broken main ground strap can cause a host of floating ground issues and erratic electrical behavior in modules like the PCM/TCM, potentially leading to false codes or improper solenoid operation. Ensuring this ground is clean and secure is a fundamental step in any electrical diagnosis.

Real Owner Repair Stories

• Commonly reported on forums like chryslerminivan.net and allpar.com (2011 Dodge Grand Caravan, ~115,000 miles) — Check engine light on, vehicle stuck in limp mode (2nd gear). Code P0762 and P0700 present.
  ❌ Tried (didn't work) Clearing the codes (code returned immediately)., Performing a transmission fluid and filter change with Mopar ATF+4. The shifting was slightly smoother for a short time, but the code and limp mode returned quickly.
  ✅ What actually fixed it Replacing the entire transmission solenoid pack with a new Mopar unit (part number 68376696AA). After replacement and performing a 'Quick Learn' procedure with a scan tool, the code was cleared and did not return. The transmission resumed normal shifting through all gears.

OEM Part Supersession History

• 5078709AA, 5078709AB → 68029389AA, 68371508AA, 68371508AB, and finally 68376696AA — Revisions to improve reliability and address the common failure modes of the solenoids.
  Heads up: While all are for the 62TE, it is always best to use the latest available part number (68376696AA) for the best reliability. Some aftermarket parts may have different colored connectors (e.g., white vs. gray) which can signify different internal solenoid configurations; ensure the replacement part explicitly cross-references the correct OEM number for your vehicle.

Model Year Variations Within This Range

• 2008-2020: The core design of the 62TE transmission and the common failure of the solenoid pack are consistent across all model years. Mopar has released several updated versions of the solenoid pack over the years to improve durability. However, the replacement procedure and the diagnosis for code P0762 remain the same for the entire 2008-2020 range.
