that they'll charge you at least an hour labor to look at it, diagnose that everything is normal or at most they will drain the pan and hopefully remember to put 8 quarts of mercon sp back in, lol then send you on your way with the same delay you came in with. ORRRR they just might have a tranny tech that knows his sheeet and he'll test line pressure while engaging R to D and D to R and maybe they'll call ford and ask for advice and maybe just maybe they'll be nice enough to toss in a brand new tranny. But, imo, with my budget I would first replace the external and go from there cuz it's only about $30 bucks to do it yourself. It's just me Steve, I wouldn't take my truck to ANY dealership hoping they have someone that is familiar with the 5r110 and is able to accuratly diagnose the symptoms. I wouldn't even take my tranny to Marc, lol, he hates working on them but knows how to flush'em. It's a complex beast and with 18k it's my opinion that there is only so much they, whoever they is, can do. Now, if your tow/haul light was blinking then I would feel better about taking to ANY dealership because there would be a code for them to read and go from there. I'm just meticulous and don't trust dealerships I'm not familiar with or haven't heard good things about. And I havent' heard any good things about dealerships in the bay.
