Hi to all.
I would liketo seek the advise from the experts on this forum. My friend owns a 2011 sta fe. She is a lady so she doesnt know much about cars. She is complaining of problems in her car. We are not sure if it is indeed with the transmission But when i searched the net, her experiences are similar to the one described in this link:

She already brought her car to the casa twice for diagnosis, but all the casa is saying is they could not find anything wrong. I asked her to be more observant and look for trends and patterns. Below are her observations:
1. Initially, incidents only happen in the morning, after about 10 minutes of driving. But recently, she was able to experience it even after an hour of driving.
2. She doesnt feel anything wrong when starting the car. Its just that after a few mins of driving and she came to a stop, she would put the gear to P. When its time to move and puts the gear to D, thug sounds from underneath will be heard and the car will shake violently as if the engine support or transmission support are loose.
3. When she starts to accelerate, the car will move unusually slower than normal. After a few meters, the car will give a sudden jerk, before normally moving.
4. When this happens, she can expect that when its time to stop, strpping on the brakes will cause the car to make sudden jerks before stopping.

This has happened 5 times over a period of 3 weeks. I hope you can help us.

Thanks so much.
