What 2019 International LT owners say
Most recent owner complaints, unedited.
International lt series with eaton endurant transmission. Eaton endurant transmission goes into neutral when air brake system is below 100 psi to prevent damage to transmission. The lt air governor does not turn air compressor back on until 95 psi of air. Leaves drivers stuck on road, while at intersections or hills. It does not take more than two or three brake applications on a loaded tractor trailer to bring air system from 125 psi of air to 100 psi of air. I've had to advise my drivers that if they lose enough air, they should see if they're below 95 psi or in the 96-100 psi zone where truck will not build additional air pressure. This is a common occurrence with this vehicle.
