My car when put into drive would make a clunking noise and lunge forward, also when up shifting and down shifting it would be harsh and clunk. I took it the Ford dealer and they said I needed a rebuilt transmission put in at a price of $5490, because the one in it had to many problems and would cost more to fix then the rebuilt one, so that's what I did the car only had 71438 miles on it.
The vehicle began shifting erratically when slowing to a stop, with higher than normal rpm range. After getting back up to speed, the transmission made a loud noise and felt as if it had fallen out from under the car. Problem still exists, and now shifting from second to third gear, and third to fourth gear are delayed and some times make the car feel like it may not shift. After seeing that there have been multiple complaints about the problem, I believe this is something Ford needs to look into further.
