I have decided on a 4L80E for my 55, with a big block. I have a chance to buy and am looking at a military surplus 4L80E out of a Humvee or Hummer as the add says. It is with out the top bell housing bolt but has the cooler lines far apart as I heard these are more desirable. Just want thoughts or input on using a transmission that is a military surplus. I know I would need a slip yolk

I would avoid it. One its probable an early one (not ideal) and two being surplus means it was beat on. The early ones 91-92 had different internal harness yes can be changed but get as new of one you can find as it will have better parts.
I would look for a 97 and newer, better internals and they updated other stuff.
