Thanks, Ken and others who commented. Apparently no one has found a "silver bullet" for immediately getting a readable level on the OEM dipstick when refilling the THM 425.

Fred,
As log as you keep the fluid at a lower side, one does not develop burping
when the transmission gets hot.
I like to replace the vent at the rear with a push in right angle tube and
run a hose out to the outside of the frame and attach an use plastic pop
bottle to catch the burp.
That fitting has been discontinued, but we managed to stock some.
It is on our web site under transmission.
