I tried starting the car and when I went to put it into reverse to back up the transmission did not engage. It suddenly lurched backwards and the same thing happened when I put the car into drive. There is about a 10 second delay and then it lurches. One time while driving the car, it slipped out of gear and started to rev the rpm over 3000 it tried to engage the gear but then stalled in traffic. I took the car to the Ford dealership and they hooked it up to a diagnostic machine. They said that there is a delay in building up pressure to go into gears. They said that they did not know what was causing it but they suspected the high pressure filter needed to be changed. That cost was 800 dollars. After changing the filter there was no change. I no longer feel safe driving this car and don't know what to do about trying to repair it. Ford said that you can get used transmission from junkyards but this seems to be a common issue. I did bring it in to the dealership in January to have the throttle body cleaned for the recall. I'm highly agitated that Ford will not stand by their vehicle.
