known issue caused by compressed air contamination according to Eaton Transmissions service bulletin TAIB-1006, which was first published April 2023. In the over 3 years since the service bulletin was released, Eaton, Peterbilt, Paccar, and Cummins(engine manufacturers) have failed to develop adjusted maintenance intervals, added inspections, or additional filtration to prevent contamination of the transmissions air system. They've instead passed the financial burden of repair on the customers by denying warranties. The dealer determined based on TAIB-1006 that the MTM requires replacement and the air system cleaned of contamination. This was based on data and not a detailed inspection to determine the internal failure.
