    What transmission are you using? was it with the LS1 or is it from an earlier vehicle? I think the LS1 expect 20,000 pulses per mile. Earlier version had less.

    The original transmission was a getrag 5 speed.
    The t56 that I have is from an LS1.
    The pcm was from a 5.3 and a 4L60e, but when I had Allen program it, I told him that the transmission was being changed to the t56. Not sure if that would change anything.

    Thanks again.
