    Torque pattern for 4L80 pan

    Does anyone know what the torque pattern is for the 4L80 pan bolts? Also, do I need to lubricate the gasket with trans fluid prior to installation?

    4L80 swap

    My truck is an '06 and came with a 4L60. I hear some trucks came with a separate trans controller if a 4L80 is factory equipped. So what do you do if you swap from a 4L60 to a 4L80 and your truck...

    Duramax MAP sensor

    I picked up a Duramax MAP sensor, part # 12623671 (3 bar I think). I plan to run up to about 18 psi on this build. Will this MAP sensor work well for what I'm trying to do?
