Thanks Dennis,

I had wondered about the adjustment at the throttle body before, while
I was correcting the idle/WOT switch, so this stood out in RG37 in
Bentley reading for the AT rebuild.  Once I have the idle dialed in
(right now i rely on the IAC and O2 sensor to keep it at 850rpm... had
it done once before but I went nuts tweaking it on an empty tank and
now it has to be redone) I will set the shift points and kickdown.

Oh, and I wouldn't exactly call it heavy, that acceleration.  I'm bad
at estimating grades, but it was fairly steep (~10%? no, i'll give up
on that), and I maybe eased back just a bit on the throttle at 45 cuz
that's the speed limit.  Well, today is for curtains, and rereading rg
37. Well, I should try it all over again because I didn't even notice
what the rpm's were...

Thanks again for all your help, Dennis.  I'll set up a stepwise chart
and figure this out...
