Now the required fluid is Mobil1 LV. It masks the issue temporarily but if you had the shudder, the damage had already been done (burnished TC clutch plates).
In the meantime the TC has also been redesigned to alleviate future issues.
I only recently left a Chevy dealer where I worked as a parts-to-service liason and can assure you that the TC has a new part number as well as revised TCM programming. I can also assure you that Mobil1 LV is NOT scarce, we kept cases of it in stock, find another dealer.

Very concise information, particularly about the revised converter and program. Thank you
