Q: Hesitation when accelerating

asked by on February 01, 2017

I recently replaced my transmission with a used transmission with about 172k miles on it and had no issues until tonight coming home from work. As I started up A steep hill my truck would not accelerate past 30MPH and seemed to bog down every time I put the gas pedal to the floor and there is no check engine light. Problem continues even on level ground... What could the problem be????
My car has an automatic transmission.
