I've got a number of possibilities for my truck this year and recently I found a 4l80e , for a decent price, but it has a built in drum brake on the back. it's out a mid-90's box truck. if I do buy it I'll be going with a manual valvebody. anyone know if there were different size drums that were available? is the drum something that can just be removed without a problem? or if I keep it on will it remain somewhat reliable. I try to avoid the really deep mud. will there be a problem to run a single u-joint(no shaft) to mate the 4l80e up to the divorced 205, if so what? regardless of the above... I'm going to do a caddy disc swap on the 14b.
