Clunky 2-1 rollout shifts (Latest mechatronic firmware updates not performed)

This software must be different than what DINAN offered, because when I had my 4.6iS - I had DINAN transmission software installed and it did not cure the 2-1 clunk. New transmission oil service did not cure it either. Only sport mode was able to eliminate the 2-1 clunk for me.

I always believed it to be a temperature issue since it only happened at 'normal operating temp' or at least what was indicted. Or solenoid issue.
