How's the output shaft seal?

I went through a few 42RE units, they're decidedly not heavy duty. If you
did damage you'll notice that it doesn't like to shift into overdrive while
on the throttle. The OD unit is last in line to get fluid and has the
smallest passageways so they clog with metal first. The last time my trans
was built, they upgraded lots of parts inside and enlarged the fluid paths
to/from the OD unit. I got 80k out of it without issues, the first 3
transes only lasted 10-12k each.
