Possible reasons for the Hyundai automatic transmission jerking when driving:
Mechanical problems:
*Low transmission fluid: Low fluid levels can cause clutch slippage and loss of power.
* Worn clutches or bands: Over time, these parts wear out, leading to rough shifting and jerking.
* Faulty solenoids: Solenoids control the flow of transmission fluid, and faulty solenoids can cause the transmission to shift at the wrong time or slip.
*Transmission control module (TCM) problems: The TCM controls the transmission and a malfunction can cause the clutch to not operate properly and shift gears incorrectly.
* Worn bearings: Worn bearings can create noise and vibration and make shifting difficult.
Electrical problems:
*Faulty Sensors: Sensors such as the transmission speed sensor or throttle position sensor provide the information the TCM needs to control shifting. Their malfunction can lead to incorrect gear shifting or jerking.
* Faulty wiring or connectors: Damaged wiring or poor connections can interrupt communication between transmission components and cause shifting problems.
Other reasons:
*Poor quality transmission fluid: Improper transmission fluid may not adequately lubricate and protect transmission components, resulting in jerking.
* Dirty Transmission Filters: Dirty transmission filters can restrict transmission fluid flow and cause shifting problems.
* Engine Problems: Engine problems such as misfiring or fuel delivery problems can affect transmission performance and cause jerking.
Recommended actions:
If you are experiencing automatic transmission jerking in your Hyundai, it is recommended that you seek professional help as soon as possible. Schedule a diagnosis by an authorized dealer or qualified mechanic to determine the exact cause and make the appropriate repairs.
