    I think its just the computer at work not seeing it for some reason. I pulled it up on my laptop and I can see it now. I cant see anything in torque management that is causing the issue. I wouldn't think that the default trans limit would be accessed as it appears to only get accessed when the tcm has communication failure.

    Do you have the A/C when the timing is dropping? If so, zero the A/C Torque Reduction table.
