Hello all, especially Daryl

I installed Redline MT-90 in my '85's tranny a couple months or so ago.
I've noticed that shifting has gotten progressively more difficult,
especially when the tranny is warm, and especially when downshifting (to the
point of really not being able to pull the lever into third or second gear
on a hill).

Should I have used MTL?

I think it was a bit overfilled, and pulled about 500ml out this evening,
and haven't really driven it yet for much of a test.

Thanks for any input,

Karl Wolz
