New TSB For 8 speed clunk and shudder?

[cardude2000]

I could have sworn someone here listed an upcoming TSB to deal with this. Can’t find it now, can someone point me in the right direction? My lurching/shuddering/searching/clunking has gotten progressively worse....

My truck went in yesterday for the current TSB, there is a new one but I was told it was going to be late Jan/early Feb before they actually begin doing it.

I was told by a Service Adviser that a new fluid was going to be used after the first of the year.
