Check trans fluid,and intake manifold for carbon build up,
if trans fluid is low fill up,if you stil hear winding noise in trand ,might be the pump inside trans,if noise goes away,then check tps function,throttle position sensor also control transmission shifting,
hope these help.

My '03 Mustang started acting funny today. I


i"ve heard that these year model have problems with defective MAF (mass air flow sensors. i only mention this because i just saw a you tube and a mechanic had mentioned that..but the sputtering could be caused by a number of things. sounds like it could also be a fuel delivery problem, possibly a sticky fuel injector..you can try a quick easy fix by trying some Sea foam fuel treatment and drive it around for about 30 miles to see if that will clear it up. Also does you car idle properly? I mean does it lope or surge? because if it does you may want to clean the IAC (idle air contol), this is just a recomendation, my car was doing this and i never ever seviced it before, and you should have seen the biuldup of crud on the pintle, i cleaned it, and now it idles perfectly. it only took me 10 minutes to take off and clean it. hope one of these suggestions helps if not please get back to me.

It would be one of 2 things. Either the transmission is very low on fluid or the pump inside it has gone bad. Check the fluid first. If the pump is bad call the rebuild shop to see if there might be warranty left. Hope this helps.
