hello all. I just spent 3100 $ on what the local ford dealership said was a bad trans. my problem is still with it. no check engine lite. starts and runs ok. but at hwy speeds usually in overdrive while going up hills it starts jerking, just a small amount almost like a miss but tack stays steady. I can accelerate out of it. it gets bad on hot days when I turn on the AC I have changed fuel filter, air filter, plugs and wires. even the shocks still with me! any help from you guys will help me!
