Owner report 11639536 · 2025-01-30 (January 30, 2025)
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 rpm’s 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.
