Total volume is of little significance to this excercise, as various
amounts are held in coolers, lines, torque converters, and fluid
passages within the transmission. A filter change uses a couple of
quarts on this transmission, while the total capacity several
gallons.....

If you haven't been informed yet, the fluid passages are different
between park and neutral (hence the manual tells you to run the engine
in neutral if it has overheated, right?). Do the test I listed at a
known "delay" start, just run it in neutral for 10 seconds or so, then
shift into gear. If it makes a marked difference, well then you at
least have a stop-gap measure....but either way, I'd park that sucker
at the shop's front door and leave it there until it was fixed.

Mike et al - along the same lines, this trans is a "Hot, Neutral"
check.

 

a few quarts of trans fluid can cause pump damag3e never tow in overdrive
period
and the new trans is junk amd make sure they use atf4 and a relearn of the new
trans is done and have them check pinion factor to make sure tires size is
figured in
