The is no receptive "click". It is just when it is in motion. It really is not that bad, but enough to concern me. It is a little louder than the granny gear on a Chevy apache. It is the original Tranny. It may be that this tranny just makes this noise in low??? The one thing about the car that I like is that not many 42 fords were made. I will drain it out this weekend and let you know.
