Well selah, consider yourself lucky... My E4OD let out all the magic smoke two weeks ago...
Had to buy another vehicle when I saw an accordion spring from the rear sprag laying in the pan...
Transmission had over 250,000 miles on it...
I'd say that if you're hunting for gear, take it in before all the gears turn into neutrals...
I was going to rebuild it myself and want to but the money wasn't there... Guess I'll wait till August or so...
