    Angry Bad Shifting Automatic

    I hit the revlimiter before my auto shifts usualy only when going from 2nd to 3rd gear doesn't matter if left in drive or manualy shifted ?
    edlebrock says there is nothing wrong with there program which has me locked out to adjust things.
    puzzled and pissed!!!!!!!!!!!!!

    This is a tune problem. Worst case scenario your stock transmission is getting 'lazy' with its shifts. My stock AODE started missing shifts because it couldnt handle the extra torque I was pushing through it. I think my auto made it 5 months after I installed the blower. I had 70k miles on the car at the time though.

    Far as I know the 5 speed auto's should be able to hold the power. Eldebrock should lower the shift command for your 2-3 shift.

    If they wont than maybe look into getting a custom tune from some of the vendors here.

    I remember talking with you about this at the Ford vs GM day. I thought stage 3 was tuning the car.

    I would see if PSR can tune it in on their dyno.
