My wife and I bought a 2009 Hyundai Accent in August of 2009. Since new the car has made weird transmission sounds while idle in gear, or reversing slowly. The car also shakes during the latter once in a while. After about 3,000 miles, the transmission started clunking, especially up hills when shifting from 4th to 3rd. It feels like running over a rodent when it clunks, so its not just a little slip of a band or adjustment. We took it in. they said it is fine because it wouldn't clunk for them. The only problem is they test drive flat ground in the city at lower speeds. This seems to happen going uphill and randomly. The mechanic then told us to keep driving it, and it won't hurt anything. He wanted it to get worse before they took it seriously. Well since the last time we took it in the clunk is getting worse, about 5 times every 200 miles driven. During one such clunk the car actually stalled from about 50 mph to around 35 instantly jerking the car and my wife. She said it felt like a manual transmission vehicle that was stalled. What could possibly be causing this phenomenon? They checked the computer for codes, there were none. And they reset the transmission shift points and the auto relearn sequence. So it has to be an actual mechanical problem. I don't want this problem to cause an accident, or damage the vehicle any further. Hyundai refuses to believe us. If anyone is having this same problem with this vehicle, or if anyone might know that the problem sounds like it could be. Possibly then I could present them with that information. Thank you very much for your time. Chris

I have made a complaint to corporate. We live far away from any of the Hyundai dealers, and they want to keep the car for a while to evaluate the problem. Which brings me to them lying when we first bought the car. They stated that the warranty covers rental/loaner costs, but after the contract was signed and the first issue occurred at 600 miles they denied ever saying that. I live in a mountain range, mountain driving is when it puts on its best show. All the dealers being located in city's they will not be able to verify the problem. So I hope with some expert opinions and documentation of when/how it clunks we will be able to get the car fixed without the hassle of waiting till they can hear it. I know this clunking is damaging parts of the car they will not replace, but they say don't worry it isn't hurting anything. Thank you for your time and opinion.

The overdrive wire under the overdrive switch or the gear shifter I keep reading about them messing up and shorting out. This causes similar problems to what you're having The overdrive wire under the overdrive switch or the gear shifter I keep reading about them messing up and shorting out.
