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.

Those arent the ones im talking about. the ones im talking about are in the accumulator body itself not the shift plate.

they are exhuast holes, used when the plate is installed.

The plate redirects everything and closes off the vent, thus the need for the holes.

I don't think they have any effect, it's the wholes in the plate that change how the shifts feels... at least thats how we tuned it when we put mine in.

the holes in the plate effect shift feel, the ones in the accumulator casting do not.

The two holes need to be drilled in the casting if you use the plate.

No plate no holes.

Yes.
That's why BBH said vent before.
