What effect does enlarging these holes have on shift feel And shifting gears? Im talking about the two that are drilled in the accumulator body. it is a tugger kit for the 4r100.
When I got my BTS VB, there was a plate with it from Transgo. There were THREE holes that were modified. Each of them controlled the firmness of the shift. If I were you, I'd give BTS a call and ask brian which hole changes what shift.
