You needx to have the codes pulled in order to see what the computer is complaining about.

you will need a scan tool that is capable of reading manufacturer-specific (in this case, FORD) codes.

thanks Steve I was afraid of that. the only difference that I can tell is that I can feel it shift from 2nd to 1st when I slow down. I will go and have it checked out

You usually can drive up to a mile or so without making it worse. Sometimes more than that, sometimes less than that. Sometimes you'll destroy the trans in the first 50 feet. It all depends on what's wrong with it.
