I currently own a 2011 Jetta SE 2.5. This past summer I brought it into 2-different dealerships complaing about a shudder in the transmission that happens between 20 - 35mph. It had about 5,500 miles on it at the time. The shudder would happen about a couple times while driving to and from work each day. Well both dealers inspected the vehicle and of course could not replicate the problem. The dealer who I purchased the car from did check the tranny fluid and said it was fine. Since the problem couldn't be replicated by the dealers I decided to be patient and to re-evaluate the issue again at the 10,000 check up. The weather here in Michigan has been quite cold. The shudder has now tappered down to about twice a week instead of daily. The transmission is now shifting hard (clunk) from 1st to 2nd gear for about 5-10 minutes and then it smoothes out. Is this common nature of the 6-speed auto tranny during cold weather?? The car now has just under 9,000 miles on it. Once the car is warmed up the the car will shift rough from 2nd to 3rd gear at moderate throttle, while excellerating from a stop. To see how often this happens, I tested the car in the parking lot, and the rough 2nd-3rd shifting happend about 6 out of 10 times while excellerating from a stop. So, not all the time. It has been doing this for the past 2-months. The car just doesn't shift smooth consistantly. Now while driving I anticipate/think about the rough 2nd-3rd shift before it even happens, which is wearing on me to say the least. Besides the tranny, could there be anything wrong with the throttle calibration? I plan on bringing my car in next month for the 10M mile check up. I love the way the car drives, expecially coming from a 2010 Honda Civic. I can deal with all the hard plastic interior parts VW loyalist have complained about, but a poor shifting transmission is something I cannot accept. I would appreciate any feed back on what the problem might be and any information I could pass on to the VW tech to help better indentify the problem.
