I'll refrain from posting any technical details because there are lots
of other people here who know a lot more than me.

But, lots of people have had good luck in just having the fluid and
filter changed. While they have the pan dropped to do that, they
might be able to spot any other problems.

One thing I would advise is to NOT WAIT ANY LONGER! If you keep
driving when there might be something wrong, you could end up damaging
it to the point where the transmission is shot. (Of course, they you
could buy a new stout one from APS Precision...)
