2016 ram 2500 6.4 check engine light

[Jbarganier]

Check engine light came on, throwing code Po375, error 5th gear ratio. I did feel transmission slipping in 5th, has plenty of transmission fluid, and it looks clean. Truck has 85k mileage. I have looked up several things and am more confused on what is actually is.

Thanks Jim

Did you ever resolve P0375 ?
