put a transgo 46mod vacuum shift modulator in the valve body, get rid of the POS electronic EPC. Oh yeah, you'll need the bypass for boost pressure that they sell for FI applications.

its internal, the device is black and about 1.5" diameter, slides into the valve body. Programmable, not adjustable. The vacuum one requires you drill and tap the case for a 1/8 NPT fitting to bring vacuum into the transmission. A very easy modification. You remove the electronic one, leave it connected and set it to the side, and install the vacuum unit.
