The trans is all tore down and mostly ready to go back together I just decided to post a thread about it finally. I was in the middle of building a 4R100 for a F250 when we were doing this 2 weeks ago, thats whats on my assembly bench.
The other day I tore the final drive completely down. I am having the sungear, planetary gears and spider gears all iso-rem treated. My original final drive sungear was in pretty rough shape and transtar can only get 38 tooth final drive sungears new. You can buy a used one from them for $30 but they dont inspect them very close and half the time you end up with one thats just as bad as the one you are trying to replace. So I ordered a brand new 34 tooth sungear from my handy dandy dealer at a whopping $49! Hopefully when it shows up it actually really is the right part because thats dirt cheap.
Heres some more of the damage, nothing was smoked too bad yet, like I said the trans still worked fine when I yanked it. Of course the wimpy OD clutches were glazed.
The manual 1-2 band was burnt up
