Downshift Clunking in Transmission

[H2Norcal]

Anyone out there experiencing an annoying drive train clunk when the H2 is slowing (15-25mph) and then accelerating (like you are slowing for a red light and it turns green).

I have driven at least 3 during my selection process and all of them seem to have it. Some worse than others. I had the same problems with a '99 Dodge 3/4 truck and it could not be resolved.

It appears to be some type of drivetrain lash when the transmission gets confused as it is down shifting and then suddenly must accelerate.

My 2500HD Sierra 6.0 Vortec truck with the same basic transmission internals does not do this.
