hector:
so i found out that i have a c4 auto the guy thatsold the mustang to me said he rebuilt the tranny and had a bnm shift kit. dont know what tha is but he says it is a little upgrade. apreciate the help

Soaring:
That is one tough transmission.  Keep it.  Look into getting some gears for the rear end.  You most likely have an 8" pumpkin, but the PO may have put in a 9".  Get back with us if you don't know the difference. 

hector:
your right i dont know what that means but im sure i can learn

Tim175:
Does the rear end housing have a "hump" on the back for it? If it does than it is a 9". Also if you can put a socket on the two bottom bolts of the differential than its an 8" because if it is a 9" you cannot put a socket on it, you have to use a wrench.

Soaring:
Yeah, the 8" is round.  The 9" has a protruding "hump" on the back of it.  Most likely yours is an 8" like mine.  They are tough differentials and can take a lot of abuse.  When you find a nickel in a pig track, take the car to a differential shop and have them install a 3:55 gear.  You will notice a big difference in your launch after that.  Right now, you most likely have the 2:78 gears.  Those are great for everyday use, to include highway driving, but lack in performance from light to light.  Don't try to install the gear yourself.  It's just too complicated.
