    How many miles? Has the clutch ever been replaced?

    You really need to have it diagnosed properly with Vcads.

    got this truck a month back. clutch feels strong, good pull, rpm not fluctuating, smooth shifting.

    By any chance you using manual mode when you pull up to stop. It happen to me couple times when i stooped at lights and i was driving in manual mode and forgot to down shift gears, but i didn't see a ck transmission message.

    is the hill assist enabled or does it work . possible something wrong with hill assist but it would not say check trans anyway, what kind of code is pulling up when check trans is coming on.

    I have similar problem I put it into drive but can’t get any acceleration same goes for reverse. But once I shut it down in on few times with pedal pulled up. It seems to work sometimes changing from Netrual to reverse it feels a little rough not always.
