I have a 2008 Ford Edge, about 83,500 miles. My transmission started to stutter, jerk before shifting. This happens about 40-45 mph and around 60 mph. I took it to the dealer where I bought it. Now 3 vists later and spending $1700 for a new PTO unit and seals. I still have my original problem. It is most noticable when going up an incline. The tranny stutters, jerks, then RPMs climb and speed picks up a little. This is starting to happen more. The dealer does not know what is wrong with my car. Does anyone have any ideas?
