90 SP36 downshifting

[williamcharrison]

I just returned from a 500 mile trip in my BB and everything was fine
except that the transmission did not downshift correctly on long steep
hills. If the hill was steep enough the coach would almost stall
unless I pressed down on the accelerator quickly.
Come to think of it when accelerating from a stop the upshifts
seem to occur very close together also. If there is a simple fix I
will attempt it myself, otherwise I need to find someone close to
Akron, Ohio to make the adjustment/repairs. (The trans. econ/pwr
switch was on pwr).
