    Question on stock 2011 SIerra 6l80 transmisison shift pattern type

    Hi all,
    I was looking through my tunes and noticed my Transmission Shift Patter Type was
    Pattern A Pattn 1
    Pattern B Eco Mode

    I thought I remembered them being
    Pattern A Normal
    Pattern B Trailer

    Then in Tap-Up / Tap-Down - Range Active has:
    Range Active D4

    I thought I remembered it being
    Range Active D6

    I have not made ANY changes to my stock tune, can someone let me know if I am going crazy?

    Thanks,

    Ben

    It is what it is.

    There are many different calibration files for each year and they differ from year to year.

    A 2010 truck I used to own was Pattrn 1 and Eco, my friends 2011 was Pattrn 1 and Eco while my 2012 was Normal and Trailer.

    The 2010 was a 5.3/6L80e with Z71 package, the 2011 was a 5.3/6L80e LT and standard 4X4, the 2012 was a 5.3/6L80e Z71 package truck.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    To be honest, no not really. The 2010/2011 are D4 and the 2012 is D6.

    TUTD still worked no matter what when in Manual mode on any of those trucks.
