    When I am tuning the MAF I make sure the po101/2/3 are set to fail on 2nd so I don't get any codes while driving.

    You are telling me I need to turn off my max line pressures?

    When I re-enable the MAF and STFT and load the tune the line pressures drop and it doesn't shift as hard which I am ok with. It is the inconsistent shifting between 3-4 that I am concerned with. Because it doesn't do it when I am in SD tuning.

    The VE tuning LTFT+STFT 11 tune that you looked at should have the MAF failed for VE tuning. If it isn't I will have to check the tune when I have access to my laptop.

    Not sure how you misunderstood. It's pretty clear what I typed out.

    edcmat, I got it now. I was thinking about the engine diag. I had not done anything with the trans diag. so I honestly had not paid any attention to it. Sorry about the confusion.

    Disabling the line pressure will help with the firm shifts during my VE tuning, but other than that is it suppose to help anywhere else? I am ok with the hard shifts while tuning. I'm not doing any WOT pulls that would cause the trans to shift too hard.

    Tune and Scan with update

    Here is the latest tune with your updates to the tune and a scan that I did with the adjustments. I Also disabled the max line pressure in trans diag.
