    T-56 to 4L80e swap trans shifting issues... see any issues?

    Recently installed a 4l80e in my Camaro behind a LQ4. Car was previously a T-56 car. 4l80e has the segment swap harness. I got a base tune to get the engine started and fluids circulating. I took the car around the neighborhood and the speedometer reads like 20mph faster than what I'm actually going and the car feels like it wont shift out of 1st gear...any ideas suggestions?
