48RE downshift clunk 20 to 17 mph

[R. Weber]

I have a 2005 2500 which clunks when it down shifts between 20 and 17 mph. It is in the dealer having the valve body replaced. Is there other problems?

I'll guess that the valve body swap didn't change anything...

Mine has this also, especially on light throttle, I don't care about.
