Hey I have a 95 3500 with a 6.5 diesel.. my 4l80e has finally given up the ghost. it has no reverse and is slow and i am sure the torque convertor is shot...

So here is my ? I have an offer to swap with a trans from a 96 454, will it work? and what does it need to do work.
and I am fairly mechanically inclined but have never done a trans. Is it worth the effort to rebuild one?

info, tips or local help would be greatly appreciated. thank you.
