Thanks everybody for the help and direction, turned out to be a bad transmission output speed sensor, been running good so far.

Ya it's a Mdrive, and yes 613 sorry about that.

Who has any idea what is going on with my truck, 2013 CXU630. I'll be driving and it seems like it loses half its power, turbo psi is only like 20 instead of 35-40, speedometer gauge reads zero, digital display shows - -? for mph, and there is an "I" on the display screen by where it shows what gear im in. No cruise control or engine braking works either while it does this. Is this heard of or do I have a wiring gremlin I need to figure outm
