    Default Tranny hanging in third gear

    Started 2 days ago with 2 codes on cold start p0700 and p0847
    Completely stock tune
    Shift happens @ frame 312 in the log then doesnt seem to fuel after that even tho i gradually increased throttle.
    Letting off the throttle then getting back on seems to make it ok

    Have you changed your fuel filter? I would start there.

    Have you looked up the codes? The codes indicate a sensor/switch may have good bad.

    You are in a classic ECM rpm defuel limp. It is usually code induced. "cold" symptoms suggest tranny fluid or switch related.

    I left the PTO switch on..
    The codes were not related to the 2000 RPM limit.

    It has been throwing those codes in extreme cold starts and wont shift out of third tho..
