I did buy that book months ago since i was planning to rebuild one or the other, just fely like rebuilding it was a little overwhelming compared to a engine lol
Rebuilding that transmission is ten times easier than rebuilding an engine..
I've been debunking that notion ever since I rebuilt my automatic.. what transmission gurus would have you thinking it's some kind of magical Act of God to rebuild an automatic transmission when it's just about the easiest thing you'll do on your car... Especially the 904 or 727 which are damn near alike... They are literally the easiest.. I rebuilt my friends 350 turbo for his Trans Am and had twice as many parts in it amd still not that difficult...
Once you take everything off the outside of the transmission all you do is tighten the front band from the outside, you pull out the pump or actually the trick is to push it out which took me a lot to learn but after that you can unloosen the band from the outside that's holding the front drum from coming out with the pump and then pull the front drum out and the rear drum as well and then the rear band just comes right out as well what the front Band. Behind that is just the rear shaft that's connected to the sun cluster gears which all comes out as one. At the bottom is the sprag which is just ball bearings and Springs... Oh yeah you first one to take off the tail shaft which is just a big c clip underneath the mounting pad and 4 bolts.. also first you would drop the valve body which is 3 bolts for the filter and 10 bolts for the valve body.... Once you've done it you can do it in your sleep... speaking of sleep it's easier than falling out of bed...
Each one of those drums is almost like a dirt bike clutch or there's a clutch and a ring in a clutch in a ring and a clutch in a ring and so on. Then there's is a bunch of seals that you just take out and put new ones in being careful not to damage them.. buy a large of generic Vaseline and use lots of it everywhere...
