I have the same problem with my 2017 kenworth T680 cummins ISX15 with Eaton Fuller transmission this is driving me insane someone please help me with these. My dashboard says transmission fault code and the service light next to the shifter flashes and then it does not let me shift into gear I turn it off leave it off for 2 to 3 minutes and then when I turn it on not only does it shift without a problem like nothing happen but the fault code is gone from the dashboard what is going on here.

We have a 2018 KW T680 and had this problem. Took it in to a KW they had Eaton do a software update. Article attached can provide more info. Truck is running well so far I’ll update if any other problems
