    I would really question the "driving style" problem, and ask them to in detail explain how that is the problem, come back here so we can point out the bs in there return to you.


    5k on it shouldnt be any kind of failure but we have all seen it worse, I would go back and refuse to take it back until its problem is identified.

    Driving style is not an adequate answer.

    One thing to consider is reflash the transmission computer. Disconnect both battery terminals and let it set for 10mins then reconnect. The computers "learn" your driving habits and adjust the shift patterns. They also have some strange shift/downshift points themselves.

    It sure is on some instances.

    Had more than one that wouldn't shift correctly.
    All sorts of different parameters from shifting like your saying as well as not shifting into second till 30 miles an hour.
    All came back to how the driver was beating the snot out of the vehicle in a couple of instances as well as running the trans as a stick in others.
    The ecu has adaptive memory and learns this and tries to adapt.
    Have also seen an issue or two right off the lot.
    What should be done is a ecu memory reset and then the tech needs to drive the truck easy (like grandma) for 15 or 20 min in stop and go as well as easy acc to speed. Let it cool off to cold and drive it normally again to see if the condition has improved.
    Any shift concern like harsh shift or irregular response throws red flag up to me and before I go to far I road test it and if I think it may benefit I do a reset.
    A lot of the time it resolves the issue.

    Not saying this will resolve the issue but it should be tried.

    Just because you may not like the answer doesn't mean it's wrong.

    Sorry to disappoint you but not all of us throw BS....

    I thought there was a TSB for reflashing the computer on the '12's. [​IMG]

    Telling him its his driving style and sending him on his way IS a BS answer. Thats why I told him NO that is not an adequate answer, explaining how his driving habits is causing an adaptive system to not be able to correctly learn it, offer to reset the ECU and teach him how to allow the ECU to learn is the CORRECT NON BS answer. so back to what I said earlier.

    ITs a BS answer go back and ask specific questions.

    On paper document the time, date and person you are dealing with. If after several attempts you are still not satisfied contact your State Attorney General office and open a file with them (It is free to you, compliments of your taxes) Then sit back and wait for the fireworks as the Big Dogs rip them a new asshole.

    Just ask them if the would please do a reset. These trans are not what anyone is use to. I did a reset on mine when I got it.

    They downshift on decel with your foot off. If it shifts and you take your foot off it can do some weird stuff.

    Myself I don't like software in these transmissions.
    Mine shifts harsh (old days normal) sometimes.
    I bought mine over a year ago and I'm still getting use to it.
    Until they come out with a software update to smooth things out not to much we can do on our end.

    They all act a little different.
