04 bullitt tranny, what years will fit?

They only made the bullitt in 2001.

Your 2004 Mustang is a regular GT, which has the t-3650. Other models that have this trans are mid-2001 to 2004 GT's, 2001 Cobra, 2003-2004 Mach 1's and a real 2001 bullitt.
 
That's good to hear. I hate when I see someone selling a Mustang that is'nt what it's suppose to be, or a person who bought it thinking it's what it was. That's what I hate with all these dealer decal add-ons they have now. I saw one the other day that was an '07 GT with "Boss" decals on it. :nonono:

Agreed. Dealer decal packages are the worst. :nonono:
