Unfortunately, we can't really tell what is wrong with it until we know what the code is. You can take it to a trans shop, or find someone who has a higher dollar scanner, as the ones at Autozone cannot read Ford transmission codes. However, if the trans shop tells you what they think is wrong with it, take it with a grain of salt. Shop around, and you'll see that the trans shops diagnosis' are all different. So, just get the code and post back here so we can tell you more accurately what the problem may be. Trans shops are trained on transmissions in general, and not each specific quirk a specific transmission has. That's where we come in.
