removing trans check valve 42re question

i read on JU that the 42 re will last well with fluid changes and the check valve removed. im guessing this is the one in the line where it goes to the radiator.

any truth to this?

no advantage to removing check vale
possibly slightly better cooler flow
the drawback will be the torque converter will drain out overnight and you will have a huge delay first time you put it in gear the next day (unless you install a shift kit)

every now and then when i put it in drive it will kick really hard going in. is that what that is? the torque converter has drained out? what can cause that?

also when ive been driving it for a while going into reverse makes a clutch chatter type noise. what is that?

clunk going into gear
-high clearance in the forward clutch
-worn low sprag
-high idle speed
-drained converter
-slack in drive train
ect, ect ...
reverse problem could be low pressure, worn high clearance on the direct clutch, worn or missadjusted low/rev band

well i know how a converter works, the low pressure thing, can that be caused by more resistance in the return line of the radiator trans fluid cooler?
