Dennis
all good points
  My only comment to this is that if the lever on the side of the trany is
not in the correct position due to a worn or missadjusted throttle cable
then the shifting will not happen when it should. The adjustment is above
the spare tire
see Bentley under fuel supply page 30.32 for more info on cable adjustment
page 37.13 does not cover the the cable adjustment as apart of shifting
adjustment
 I have pointed this out to Stan (Spankie) Walhfarth at Bentley and a
mention of cable adjustment will be added to page 37.13 on the latest
printing of the big green book due to go to press any day now. I hear the
front cover will have a new look.

> Is it not shifting up from 1-2 or 2-3? Since the fluid and filter has been
changed, I would next check the governor. This is what controls the normal
shift points. A have seen debris that got past past the filter keep the
balls from seating. If ATF is getting into the final drive, the governor
seal may be the cause. This can be replaced with the trans in place.
Usually, poor up shifting is due to insufficient pressure in the system. A
bad piston or internal seal can be the problem. The 2nd gear brake band
piston seals are easily serviceable. The Bentley does detail pressure
testing the trans to determine internal problems. An experienced tranny guy
can also drop the valve body and air test the clutch pistons.
