The engine and transmission are in a 1950 Chevy truck. truck wouldn't start at first. sent the engine computer and the trans computer to CBM for a base tune. Put everything back together. The truck fires right up and idles perfect. great throttle response. But it will not move. I have checked the fluid. I made sure the torque converter is bolted to the flex plate. lol. Transmission is plugged in. Getting several codes. P0122, P0223, P0700, P2122, P2127, p182E, and a P1915. Maybe someone can point me in the right direction so I don't have to wait for weeks for a tuning appointment. Thanks in advance.
