a727 no third gear

well, the trans has been out twice, and its been out for the second time since last nice, while I got it out, might as well replace the rear clutch seals, I replaced the entire front drum out of a bb 727 that I freshened up for my coronet, I thought that would've done it lol guess not oh well
theres a filter that's for the governor???
Well, we had a Frod that we threw an old trans that sat forever and never moved... The band popped loose off one end from rust in one spot on it's maiden voyage. Either way, it needs all new seals and rubbers after sitting that long, so it's gotta come apart. Also, there are micro line filters in two places on that unit., one at the gov. and the other in the valve body. I'd bet they plugged right up once you kicked up the rust inside.
