Transmission jerks when downshifting while slowing down. Started doing it during a recent trip and when i checked, there was no oil. I refilled. Problem returned after 2 day. Dealer couldn't identify and told me to bring it back when it happens regularly.
Problem with transmission downshifting while slowing down. When cold, the transmission gives a big jolt when downshifting. As the car heats up the problem disappears. Did the 30k service which included tranny service but problem remains.
I'm still having an issue with my transmission but the dealer didn't see any problem. I dropped off my car for 2 days in July, but the dealer said there was no problem which I'm still experiencing.
The clutch pedal would grab high, low, then stay enguaged, then a popping noise and the clutch pedal went to the floor with fluid coming out of the transmission. I had the car for 13 miles and the same condition came back, stopped working on my home street, had the service manager come out and confirm, and needed to be towed again. Replaced some valve (Service advisor said they didn't know what it was) in the clutch system and replaced the slave cylinder again. At this point it was irrelevant,the car is unreliable. Hyundai and dealer refuse to work on the car anymore, I'm Stuck.
I don't know the exact name of the part that failed, but it was some sort of acceleration pedal "link" that was faulty from the factory (or so the tech said). It caused the car to have 1/4 of its usual power and could not be driven faster than 30 mph.
