    First thing to do is check the oil level. I am not sure on Camaros, but on vettes they like to be overfilled by half a quart or so.

    Why are all the pressure pattern select fields changed? Leave them stock. Also I add 60 PSI shift pressure over stock, your pressures are mostly less than stock.

    I wouldn't disable the upshift torque reduction. Return the shift torque factor adder & adder modifier tables to stock, then multiply the cold multiplier table by .5 to reduce the shift torque reduction by 50%.

    Your problem is in the trans tables. The shift transition time in the 6L80s is EXTREMELY lazy and there's a lot that can be improved here.

    I change the tables the only thing i'm wondering is where you say to add 60 PSI shift pressure over stock. You talking about the Max Pressure taht is at 109 psi or the Max line pressure?
