Old school......and others......
I have alot of mechanic skill, and alot of experience with turnin wrenches on just about anything - that is why i will tell you now that the AOD tranny is no harder than rebuilding a QUADraJET carburator! If you have ever rebuilt carburators.....you can build an AOD! To get an idea (for free) go to MN12 website and pull off the 4R70W rebuild video and watch the tear down section - then realize there is about 1/3 less work involved when doing the AOD. If you have the time and the patience, i encourage you to dig into your own AOD tranny, or go to a junk yard and dig in one of those first. It was only a year ago I rebuilt my VII AOD tranny, still runs great, learned alot, and since then i have rebuilt several AOD/AODE/4R's - no expert, but by god they move and shift and are fun!!!
