2007 suburban
Ww just purchased it's vehicle four weeks ago.
160k miles. I was told at the time of purchase that
the trans was was replaced three mo ths prior. So
about two hundred miles into our family vacation
the truck was running fine, pulled into a rest stop
stretched our legs and what not. Got back in the
truck, started up and idled just fine, soon as I
shifted into drive the truck stalls out. Same thing in
reverse. Change out the throttle body and the mass
air flow sensor. Same problem. I'm hearing it could
be the torque converter or something else in the
trans. Need some advise here.
