I am haveing a problem with my vehicle

Its for your traction control/abs system.

I am unable to go over 45 mph when I put my foot down on the gas it won’t speed up it will jerk back It also wont show what gear Im putting it in ..my back up camera also won’t work when this stability track light come on it happens every couple days then it will ride regular for the next couple days.

It was in the shop some one charged me 1100$ to put a Tcm in and it did not resolve the problem then he trued a new fuse box and that didint work now he refuse to work on my car ...
