My car has an automatic transmission that lately started having issues. The car has around 90,000 miles on it. The issue happens when I shift from the second gear into third gear. Then, it starts jerking. It has different intensity however. It is very mild sometimes while other times, it is all normal. Do I have to rebuild the transmission or is there any other solution?
This issue could be something as simple as a reprogramming of the transmission computer, to a broken motor mount (although the jerking would probably be felt in all gear ranges), to possibly a transmission malfunction. Unfortunately, the transmission module reprogramming is best done at a dealership.
However, there might be some transmission faults stored that may be able to be read out using a scan tool with Hyundai software in it. You may want to enlist the help of a mechanic to assist with diagnosis of your car’s stalling issue. They can help determine which component(s) are faulty and help you proceed with a repair.
