    no problem, I'm always open to other subjects. BTW, they are checking the pressure manually to see what it does around commanded shift. We'll go from there. I'm not a trans expert by any means.

    With fuel type, a/f ratio and temp aside, I think timing has more to do with the engine combination than vehicle weight.

    First off, your frame rate on the scanner is very low, look at how your RPM & speed graphs are stair stepped. That's because you using 42 bytes, delete all unnecessary pids and try to keep it at 24 max. You can use my trans.cfg file, it has just the pids for trans scanning.

    Why is your WOT TCC lock speed set at 0.

    I'll have to look at the WOT TCC settings when I get home. Thanks for the config, however I'm not sure if your reply was a stab or if your trying to contribute....

    for search purposes, the problem ended up being a mechanical issue with the trans.
