If the issue is wanting to get overdrive, either spend the money for a gear benders overdrive unit, or swap to a non computer controlled AOD. Performance Automatic has come up with some seriously stout parts for the AOD that can make it almost as strong as the C6, plus the added benifit of overdrive for the street.
I guess other than looking for a stronger t-case, what will the truck be used for? Mostly street with some trail riding? Mainly off road? Mud racing? Rock crawling? Is overdrive really needed, or is it a "just would be nice to have" thing???

all i am asking is how to use a np205 with a e4od. i need od so i am not going to keep the c6 and i am not going to use an aod. someone reputable is rebuilding and updating the trans. and i have the computer taken care of, infact i am going to use this trans because of the electronic control.

How about a remote mount (divorced) t-case? Plenty of length in the truck, and you are going to have to modify both shafts anyway. Looks like a new crossmember will have to be made, or at least modified, so why bother with any of it?
Might even have a problem with trans clearance and big joints with a direct mount case (married), so why not eliminate all of the problems and just throw in a remots mount? Could even re-index it to gain back some clearance since you are going to modify the crossmember anyway. Seems like a reasonable solution and a very easy way to accomplish your goal.

A 2-wheel-drive E4OD and a divorced NP205 is the way to go. Last summer I bolted up an NP205 to my '96 E4OD, but not without a ton of work. The only easy part is that the trans and t-case have matching output/input shafts, and the same 6 bolt mounting pattern. My trans even had the notch cut out for the NP205 shift rail. I would guess E4ODs generally have this notch. The deal breaker is that the NP205 is generally compact compared to the newer aluminum t-cases that came bolted to an E4OD, so the front output yoke WILL hit the corner of the trans. The only reason I got around this is because I had to machine a new rear end of my E4OD case which broke off earlier this year. I was able to choose new mounting hole locations and rotate the t-case upward so the yoke will miss the trans. I'd have to look over my old parts to be sure, but I don't believe it would be possible to use a "clocking" ring to rotate the t-case upward enough because the t-case shift rail will interfere with existing holes in the trans mount, and visa-versa.

As was the E4OD also used behind that same diesel, so knowing that, why not just get a 1356 that is made to bolt right up to that E4OD and call it a day, for a whole lot less weight and a lower low range?
