hello fellow maximizerz i am a new member to this forum. I have a problem with my 03 2500 hd. 4WD If i hit a bump in the highway the servive brake system comes on and the speedo fluxuates about 5mph from traveling speed, i have a triple dog programer all the dtc's are the same every time, speed sensor a, transmission mil request, and control module long term memory performance. She jumps into limp mode" third or fourth gear stick" and you have to pull over put it in park kill the engine and start all over... Any advive?
