When I was driving on the highway the transmission fault error came on and my truck came to a stop on on the highway. It changed gears weirdly and kept the rpmâs high. Once it came to a stop I turned the truck off and on and it work fine. This has happened multiple times and a nationwide failure of the MTM and transmission is the cause of this. Many of my fellow drivers are having this same issues and are having to replace the whole transmission due to the MTM failing and destroying the transmission.
The Eaton 12 speeds that these trucks come equipped with are failing just after the warranty expires. Lots of drivers with the same problem.

AT HIGHWAY SPEEDS THE COLLISION MITIGATION SYSTEM WILL GO OFF FOR NO REASON CAUSING A SUDDEN HARD BRAKING. THIS SEEMS TO BE EXTREMELY DANGEROUS IF VEHICLE IS TRAVELING ON WET OR ICY ROADS, IN CLOSE QUARTER CONSTRUCTION ZONES OR IF VEHICLE HAPPENS TO BE IN A TURN. UNFORTUNATELY IF ANOTHER VEHICLE WAS FOLLOWING TOO CLOSE WOULD BE AN ACCIDENT, WHICH I HAVE HEARD HAS HAPPENED. I HAVE TAKEN TRUCK TO KENWORTH SERVICE TWICE AND THEY SAID THERE IS NOTHING THEY CAN DO. IT IS A REQUIRED SYSTEM AND ARE JUST VERY SENSITIVE. I SEE NOTHING GOOD ABOUT THIS SYSTEM. WHEN I COME UPON AN ACTUAL HAZARD IT DOESN'T GO OFF. IT IS STRESSFUL TO DRIVE AND WONDER AT ANY GIVEN TIME IF THE HARD BREAK AND LIGHTS ARE GOING TO GO OFF AND HOPE YOU ARE NOT AROUND OTHER VEHICLES THAT WOULD ALSO BE AFFECTED BY THIS UNEXPECTED STOPPING OF A 80000 POUND VEHICLE. HOPEFULLY DRIVERS WILL NOT FIND OUT WHAT WOULD HAPPEN OF THIS OCCURRED ON WET OR ICED ROADS.
