I have a 2001 Tahoe 5.3L A4 4X4. I just purchased a transgo HD2 kit. Was wondering should I go with the street or strip settings. Truck is fairly stock but I plan on putting on a whipple supercharger with a stall converter (yank probably). Another question is do I have the plastic accumulator pistons (1-2, 3-4). My ATSG rebuild manual says that only 98-99 have the plastic but never says that they went back to aluminum. When I look on the internet sites, they read aluminum pistons for 98 and newer 4l60E's. Any help would be appreciated. This is one of the first times I'm posting here, but I do alot of reading both here and on LS1Tech.
Thanks
Mike
