I hope I gave some good insight, I was sick of going to the dealership every two weeks and this last go around it seem to do a lot to my truck. To be honest the eight speeds are just terrible Transmissions. They’re not programmed correctly and personally I think the torque converters are wrong as well. But all of the issues I was having prior to the valve body replacement have reduced dramatically if not been completely eliminated.

Hope this has good insight for all of you,. I’m putting a cat back dual exhaust on it now and we’ll see if that affects anything
