What is the transmission problem with the Dodge Dart?
The Dodge Dart’s most commonly reported transmission problems center on the six-speed automatic that was used in model years 2013–2016. Owners have described rough or delayed shifting, shuddering, hesitations, and, in some cases, transmission failure. This article explains what those issues look like, why they occur, and what steps buyers and owners can take.
Background: which Darts are affected
The Dart offered a choice of a six-speed manual or a six-speed automatic paired with its gasoline engines. Most widely reported problems have involved the automatic transmission, with complaints spanning several model years within the 2013–2016 production window. While not universal, these issues prompted dealer service notices and discussions around potential repairs under warranty or recall/TSB programs. The Dart was discontinued after the 2016 model year, which means ongoing parts support is tied to Chrysler’s current business decisions and any extended-warranty options.
Common symptoms
Before diving into causes and fixes, it helps to recognize the typical warning signs that point to a transmission-related issue on the Dart. Watch for the following:
- Rough or delayed shifting, especially when accelerating from a stop or cruising at highway speeds.
- Transmission slipping or failing to upshift or downshift as commanded by the accelerator or gear selector.
- Shuddering or surging at moderate speeds (often described as bucking) around 40–60 mph.
- Harsh shifts, power loss, or transmission warning lights including potential limp-mode activation.
- Rare cases of complete transmission failure requiring rebuild or replacement.
These symptoms can arise from a range of transmission faults, and a professional diagnosis is essential to identify the exact cause.
Causes and typical fixes
The underlying issues behind Dart transmission trouble typically fall into a handful of categories. The following list outlines common culprits and the repairs that are commonly pursued by dealers and independent shops.
- Valve body wear or failing solenoids, which can cause incorrect gear selection; fixes often involve valve-body rebuild or replacement and may include a software reflash.
- Torque-converter problems or faulty lockup mechanisms, which can produce shudder or slipping; fixes may require torque-converter replacement and calibration updates.
- Software or calibration glitches in the transmission control module (TCM); fixes typically involve a software update or reprogramming.
- Low or contaminated transmission fluid, leaks, or incorrect fluid specification; fixes include fluid top-up, leak repair, and fluid/filter service.
- Internal wear of clutches, gears, or seals in the automatic transmission; fixes can range from a rebuild to a full transmission replacement.
In many cases, addressing software and valve-body issues or replacing faulty sensors can restore normal shifting. More severe internal wear or recurring failures may require a rebuild or complete replacement of the transmission.
What owners can do
If you own or are shopping for a Dodge Dart, these practical steps can help you diagnose and manage transmission concerns while protecting your wallet.
- Check for open recalls or Technical Service Bulletins (TSBs) related to the Dart’s automatic transmission using the VIN or official NHTSA resources.
- Have a qualified shop run a full transmission diagnostic, including trouble codes, live data, and tests for torque-converter function.
- Ask about warranty coverage, including powertrain or extended warranties, and whether any repairs have been performed under a recall/TSB.
- Ensure correct transmission fluid is used (many Chrysler transmissions require ATF+4 or other specified fluids) and confirm fluid levels and service intervals are observed.
- If the issue persists after software updates or valve-body service, discuss rebuild or replacement options with the dealership or a reputable shop, weighing cost against vehicle value.
Early diagnosis and documentation of symptoms can help secure appropriate coverage and reduce the risk of progressive damage. Driving with persistent transmission faults can lead to more costly repairs down the line.
Summary
The Dodge Dart’s transmission problems mainly center on the six-speed automatic that served most model-year 2013–2016 Darts. Common symptoms include rough shifting, hesitation, shuddering, and in some cases transmission failure. Root causes span valve-body and solenoid wear, torque-converter issues, software glitches, fluid problems, and internal transmission wear. Many issues can be resolved with software updates, valve-body service, or component replacements, but more severe cases may require a rebuild or replacement. For buyers and owners, proactive diagnostics, attention to recalls/TSBs, and adherence to manufacturer fluid specifications are key to managing these transmissions effectively.
