Re: changing a truck from a 3 speed to an Automatic

You need a different trans mount and a different starter the starter for the manual trans mounts to the bellhousing. The one you need for the automatic mounts to the engine block with a stright across bolt pattern or a staggered one. The auto crossmember has 2 small peaces on the ends that has to fit between the frame. I just drilled out the rivets an used only the bottem part of the crossmember my trans guy said it is strong enough.
