e4od adapter for t case

hi all, I've been reading about these adapters that connects to the rear end of the 2wd transmission that then you can use the t case on it, what`s the chances of finding one? are they still about? or are they a thing of the past? what's your thoughts.....

Wow!

If Mark hasn't heard of it then they probably don't exist. Isn't the 2WD vs 4WD coupler/output shaft the last part to be removed from an E4OD during a rebuild?

I know you can get transmission adapters for older automatics. Here's a supplier that's well known on the Oldsmobile forum I frequent. They provide an adapter to get rid of the antiquated Slim Jim Rotohydramatic transmission (the second worst automatic transmission in the world behind the 10R80).

What you need is a 4x4 E4OD, instead of the 2wd one you have.
Or the parts to change what you have to a 4x4 one, which would be a rear case, output shaft and I have no clue what else....

yes, i know what i need and i had a 4wd e4od lined up but it fell through, then, i come across this adapter whilst searching on the web, it looked like a good mod that i could attach to my 2wd e4od, i was going to swap my 2wd trans with a t19 but i have had a change of mind, looking forward i would like to keep my truck an auto, these adapters were made by a company called quigley or something like that.....if anyone had one i would buy it off of them as my 2wd e4od is a good one.

Sure enough, adapters do exist. You might have seen this already.

You can use this search engine to see if you can find an E4OD truck or van in a salvage yard near you.

A coworker of mine found a Gear Vendors in the salvage yard (auxiliary over/under drive unit) for the C6 in his Mercury Cougar.

BTW, the link I posted works for me. Try this one.
