    Trans Crossmembers

    X2 no issues with mine. Have at least 50k miles on it and I didn’t coat it so I could keep an eye if any cracks started.

    Smokes on start up below 65

    Rings are bad or a bad valve seal, blue smoke is oil

    Allison 5sp: Shifted into reverse on accident

    I think that’s correct. Also if you push the lever away from you, and towards the firewall while you’re going from 1st to drive it will not go past neutral I believe.

    Ppei tune vs edge pulsar L5P

    There are no custom tunes in the diesel world. They’re all cookie cutter tunes. For 90% of people the pulsar is plenty. But if you want your speed limiter removed and torque limiting gone you’ll need an actual tune.

    buddy's LMM is hurt

    I think you’re thinking a bent valve. If a pushrod was bent or broken the valve would stay closed.

    It was a bent intake pushrod? What if it was a bent exhaust?

    L5P Dig street Drag Race 2019 versus 2020

    My dads 18 is faster in 2wd with traction control on. In 4wd it has too much torque limiting. Doesn’t work like that at the drag strip because it doesn’t hook as well.
