Re: (ET) Well the transmission is happy to see me.

As for synthetic oil, my understanding is that seal materials were updated around 1980 to be compatible with synthetics.  That means original seals in our tractors are probably not.  The failure mode is seal swelling, which can deform the seal enough to cause a leak.  Any seal replaced in the last couple of decades should be no problem.

While drilling out the steering cotter pin, I noticed that my E20
transmission had leaked all over the driveway. Nice little puddle, turns
out the drain plug was not on tightly enough. I cranked it down harder
but should I put teflon tape around the threads or something?

I hate synthetic oil.
