What is the transmission problem on a 2015 Dodge Durango?

The 2015 Dodge Durango uses an eight‑speed automatic transmission (845RE). Many owners have reported issues such as harsh shifts, slipping, hesitation, and overheating. These problems often stem from a combination of fluid condition, valve‑body/solenoid wear, and electronic control software, and they can range from mild to severe depending on mileage and driving conditions.

Overview: what to know about the 2015 Durango’s transmission and common symptoms

Below are the typical symptoms reported by drivers and what they may indicate about the transmission’s condition.

• Harsh or delayed shifting between gears, especially during acceleration or when shifting through multiple gears


• Slipping or an inability to hold a gear, with the engine revving higher than expected for a given speed


• Shuddering, bucking, or jerking sensations during shifts or at certain speeds


• Overheating signs, transmission warning lights, or the vehicle entering a limp‑mode state


• Difficulty engaging or staying in drive when starting or moving from a stop


• Leaking transmission fluid or a burnt/fluid smell coming from under the vehicle

These symptoms do not point to a single failure site; they commonly involve the transmission control module (TCM) software, valve body or solenoid assemblies, fluid quality, or internal wear. A professional diagnostic is typically required to identify the exact cause.

Likely causes and how mechanics diagnose them

Diagnosing transmission issues on the Durango usually begins with a physical check and a software review, followed by more targeted testing.

• Low or degraded transmission fluid, including incorrect type or contaminated fluid, which can affect pressure and shifting


• Valve body and solenoid faults that misdirect hydraulic pressure to gear sets


• Worn or damaged clutches, bands, or the torque converter inside the transmission


• Faulty transmission control module (TCM) or outdated software/calibration that governs shift points and line pressure


• Cooling issues or overheating, possibly from a faulty cooler or clogged lines, leading to degraded performance


• External sensor or engine‑related issues that influence transmission behavior, such as misreads that prompt incorrect shifts

Mechanics typically begin with a scan for diagnostic trouble codes (DTCs), inspect transmission fluid, and evaluate the condition of the valve body and solenoids. Depending on findings, they may recommend software updates, fluid service, valve‑body work, or more extensive repairs.

What owners can do now

If you notice transmission problems, practical steps can help limit damage and guide a productive visit to a shop or dealer.

• Verify your recalls and service campaigns by VIN and arrange any available dealer updates or repairs


• Check transmission fluid level and condition (Dexron VI is specified for these units); look for dark color, burnt smell, or leaks


• Obtain a diagnostic scan (OBD‑II) to pull transmission‑related codes and share them with the technician


• Consider requesting a TCM software update or calibration if the vehicle has not received recent updates


• Schedule a professional inspection with a shop experienced in 845RE/8‑speed transmissions; address issues promptly to avoid further wear


• If the vehicle is under warranty or covered by a recall, pursue those avenues first, since some fixes may be provided at no cost

Addressing the issue early can help prevent more costly damage, especially in cases where slipping, harsh shifts, or overheating are present.

Recalls, service bulletins and warranty coverage

Not every Durango from 2014–2015 has a recall related to the transmission, and coverage can vary by VIN and market. Checking the VIN on official sites or with a dealer provides definitive information on active recalls and any service bulletins (TSBs) that may apply to your vehicle. Dealers may perform software recalibrations or component replacements under warranty or service campaigns when applicable.

Common categories of updates and repairs referenced in service literature include software updates for the transmission control module, valve‑body or solenoid replacements, and improvements to shift quality. In some cases, a more involved repair or component replacement may be required if wear or damage is confirmed.

• TCM software updates to adjust shift points and line pressures


• Valve‑body or solenoid replacements to resolve sticking or misshifts


• Clutch/torque‑converter issues addressed through internal repairs or component replacement


• Cooling system checks or modifications to reduce transmission temperature rise

Consult your dealer for a precise diagnosis and cost estimate, and verify any applicable recall or TSB coverage for your specific VIN.

What to do if you’re currently experiencing problems

If your Durango is showing transmission trouble, prioritize safety and a structured approach to repair.

• Drive slowly and safely to a location where you can stop or tow if the issue worsens


• Note all symptoms, mileage, and driving conditions to help the technician reproduce the problem


• Get a professional diagnostic reading and request a service plan based on the codes and symptoms


• Ask about software updates to the TCM and potential valve‑body work as non‑invasive first steps


• Discuss fluid service options (proper Dexron VI specification) if recommended by the technician


• Check warranty, recall status, and service campaigns that might cover the repair

Early intervention often reduces the risk of more extensive damage and can lower repair costs over time.

Bottom line: navigating the 2015 Durango transmission issue

The 2015 Durango’s 8‑speed automatic has a known range of transmission concerns, but many cases respond well to software updates, valve‑body service, and proper fluid maintenance. If you experience harsh shifts, slipping, or overheating, seek a timely diagnostic from a qualified shop and pursue any applicable recalls or service bulletins through the dealer. Proactive maintenance and informed decisions can help preserve transmission reliability and vehicle value.

Summary

In short, transmission problems on the 2015 Dodge Durango commonly involve the 845RE 8‑speed unit and can stem from fluid condition, valve‑body/solenoid wear, and TCM software. Symptoms include harsh shifts, slipping, hesitation, and overheating. Diagnosis usually starts with a codes scan, fluid check, and review of software; fixes may range from updates to more extensive valve‑body or internal repairs. Owners should check for recalls, keep up with maintenance, and consult a dealership or experienced mechanic promptly if symptoms appear.

Is there a recall on a 2015 Dodge Durango?

The 2015 Dodge Durango has several recalls, including issues with rear lower control arms, a potentially failing front left brake caliper, and radio software vulnerabilities.
