Folks,

A few weeks ago my transmission cooler busted mixing transmission fluid with anti-freeze. I did not drove with it for a long time and got it fixed the next day. I had the radiator replaced and the transmission flushed. A few days ago, my 2005 Dodge Neon, approximately 150k on it, started jolting while the car was deaccelerating. I do not have my foot on the break pedal or anything when this happens and this usually happens when the car decreases in speed from around 20~30 mph to a complete stop. Is this transmission related? Or is this related to bad break pads or alignment?

Thanks for the help.
