    You disabled P0757 and it still lit up...?
    With the 0411 PCM (in the F/Y-cars) the code will stay disabled (what Vince at FLT said to do).

    You would do this if your TCC was unlocking due to misfires (there a TSTATE bit indicating this).
    Also, try doing a CASE relearn first (stall converter has less mass than stock, so misfire algorithm may misdetect misfire).

    well it wasnt the trans or tc it was the ABS light that popped. I dont understand why since the hub are pretty new. Does anybody know how to turn off the ABs light?

    I think its time to take it to a dealer or independent shop and see what they say...trying to diagnose these problems is next to impossible via the web. I think there's something more going on that isnt related to the PCM flash at all, there is no reason the ABS stuff should even pop up unless there's an issue with the system itself. Ive never got any ABS codes after reflashing, and Ive flashed the same P10 in my 02 like 300-400+ times.

    Try setting P0758 to 'Not Reported" , worth a shot .
    Isn't a stock stall in the Trailblazer around 3200 ?

    Normally a regular Tb has a 1600 stall, but a TBSS has a 1800 stall. Since i have and I6 engine with a Yank 3600 stall the stall decrease to about 3200.

    Thanks! Ill try to turn off the code and see what happens.

    well i turned off p0758 and it still occurs. My friend tells me when it reaches 40 mph the noise it makes sounds like the changing gears are changing too early. why does it make this noiss?
