After diagonostics were run on the vehicle the dealership said that there was a broken transmission mount. He also said he as not exactly sure what is wrong with the transmission. He wants to first replace the mount, and then if that does not alleviate the problem---the car making bumping and thumping noises upon acceleration from stopped position-- he wants to do a transmission flush. If that still does not fix the problem he wants to replace the starter clutch.
I am hopeful that the mount is the problem, as it is apparently cracked and I am inclined to allow the dealer to replace the mount, but I would like a professional opiniion as I know nothing about cars.
