This warranty covers many components of the transmission, offering a safety net in case of unexpected issues.

Decoding the Different Types of Hyundai Automatic Transmissions

It's important to understand that not all Hyundai automatic transmissions are created equal. Over the years, Hyundai has used various types of automatic transmissions in its vehicles, each with its own strengths and potential weaknesses. Here's a breakdown of some common types:

  • Traditional Torque Converter Automatics: These are the most common type, utilizing a fluid coupling (torque converter) to transmit power from the engine to the transmission. They are generally considered reliable and offer smooth shifting.
  • Dual-Clutch Transmissions (DCTs): DCTs offer faster and more efficient shifting than traditional automatics. However, some early DCT implementations suffered from jerky low-speed behavior and potential reliability concerns. Hyundai has refined its DCT technology over time, and newer versions are generally more reliable.
  • CVTs (Continuously Variable Transmissions): Hyundai uses CVTs in some models, primarily for fuel efficiency. While CVTs can be reliable, they sometimes have a different feel than traditional automatics, which some drivers find less engaging.
