There's no vacuum connections to the tranny (that I know of) - it's got a dedicated electronic controller. Even the hammer down downshift is electronic.
Besides - the 'hesitation' was noticeable in, or OUT of gear...
Thoughts?????????????????????????????

The reason I mention it is because when I used to have an auto car and ran a double pumper holley carb, the secondary opening always introduced too much air without the fuel flow (weak vacuum signal and a large plenum). getting the accelerator pump to squirt more gas sooner covered up the hesitation.
your calibration in software assumes the stock flywheel weight and maybe less drag right off idle. basically the light load fueling table and enrichment part could use some more fuel to see if it helps. Just thinking out loud, but this happens all the time with big carbs on automatic hot rods. You converting to automatic made me think of this. Also I have a friend who put a cam etc in a TPI car (auto) and has the same problem. this is also a speed-density car so I'm guessing enrichment is needed.
