Is you IAC motor working?, A stuck IAC will cause this issue because it cannot adjust for load. Converter Clutch Drag is VERY common on high mileage 4L80E's because the lack of "Lube to Line" bypass on stock units, Is this a rebuilt unit? This usually rears its ugly head when the unit is Hot/At operating temp. I'm not a Tuner, I wish I was!! Boosted C10, BrewCity, or Hart Rod will know more about that. I take that back....I don't wish I was, My plate is full enough Pressure Rise, Pressure Rise, Pressure Rise |
