tranny's for a '95' f150
 

Hey out there,
I wonder if there is anyone out there that can help me out. I've got a '95' f150 with a stroked and supercharged 5.0L. The motor is pretty potent, but my tranny is lacking. It's a stock hydraulic 5spd. My question is, does anyone know of a 6 spd I can set up behind it. Will I have to modify the hole in the floor for the shifter, or instead, will the 5spd from a 5.0L mustang work?
The problem I am having, is when my tranny gets hot, it is next to impossible to shift, it just won't go into gear, and it seems to like to eat clutches. I have replaced all parts once already, and am just giving up on fixing it, so would like to replace it.
Thanks for any and all help you can give me!
