We are having the same
We are having the same problem. We just had the transmission replaced by the Ford dealer because it was slipping when changing gears. Still have the same problem. We had the same problem even before the transmissiion was changed. Oh Yea!! NO ONE but a Ford dealer can get a new or used transmission for theses cars. Tha transmission will cost you $6000.00 for a rebuilt one. Thats what I said: $6000.00. We are also having problems with the engine acting like it has lost all of its vacume at times. The engine shakes, rumbles, etc. When this happens you can put the gas pedal to the floor but the rpm does not change and you go no where. You have to shut the car off then wait for the problem to clear. You also get indications: Engine Fail Safe Mode and Engine Check Light along with pictures of a wrench and engine on the dash board.
