Question type: Maintenance & Repair

Recently put a brand new create motor im my 2008 f150,

or anything in park or neutral, In fact you can recline the
rpms in park or neutral and everything seems to run fine but
as soon as I put it in drive or reverse (put any sort of load
on them drive train) the truck seems too fall on its face and
almost stall. Does anyone have any suggestions on what

scan for codes even if the light ain't on , scan tranny for codes if that's possible , check for vacuum leaks -loose broken lines , motor to chassis ground .
