I think my 727 is fried. Now I'm at a crossroads...

A guy brought in a 727 with deep pan and completely filled with fluid. I drained it out like 2 gallons and put it into my 98 Voyager when I put the new filter in. Works fine. And asfaras clutch clearance, when I rebuilt my first trans as 904, back in 80, I had no book or video or internet ; nothing. I just slapped the new parts in without checking anything, and it worked great, so checking clutch clearance on a 904; with stock parts, is pretty much a no brainer. Twenty thousands, not enough....one hundred and twenty thousands...maybe too much...
