I have a 91 mustang 5.0l, just changed my transmission from an AOD to a C5 from a ford half tonne,its a strong transmission the problem now is that in drive at about 55mph the rpms are at about 3500 rpm,pretty sure I have 3.73 in the rear,I guess my best bet would be to go to a 2.73,any opinions would be appericated,thank you.
