So...
If I go out to my van right now and start driving around, it will shift
like butter.  I mean reallly smooth.  I just put redline mt90 in 2 weeks
ago, and it feels like it.

But after driving through the city for ~30mintutes or so, it gets tougher
and tougher to shift, to the point where it takes a couple tries to go
from 4th to 3rd gear.  Next day?  Smooth as butter.  What's going on?

On a possibly unrelated note, the shifter (not the tranny, I think)
sometimes makes a sqeaking noise along the 1st-2nd gear axis, kind of like
a window wiping noise.  Is there anything I can lube to fix this?

Thanks for any help on these!
