Thread: lq9 safe shift points?

    lq9 safe shift points?

    Ok I have searched and searched. No luck.

    When I went 4l80 my shift points magically changed.

    It shifts at 5200 1 to 2nd. Then 5200 2nd to 3rd. Then at 4800 to fourth.
    Engine is a stock lq9 with a tiny cam and dual gold springs 8psi.
    What should it be shifting at? Safely. I don't wanna scatter it .

    Also can I just change the points in hptuners at wot shift rpm vs shift - performance? I am an idiot when it comes to hp tuners.

    Thanks in advance.

    I spin mine to 7000 and I have built a few that are in the same range. So anything up to that should be fine. I wouldn't go any higher without some bolts.

    the "performance" mode is towhaul, it would be better to change it under the regular wot shift rpm vs shift and x2 what jon said, my lq9 turned 6500 ALOT and that motor still lives on today!
