my buddy is looking at getting a viper t56 for his stang. he found one out of a 2003 viper but i was wondering if it is the same trans as the viper spec t56 like i have. i would guess that they are the same except the bellhousing of course. if anyone knows if we can make the tranny work with a 4.6 let me know b/c he can get if for $1000 cheaper than a D&D unit.
