Have a 2005 Freightliner with Eaton Ultrashift

Customer Question
Have a 2005 Freightliner...

Have a 2005 Freightliner with Eaton Ultrashift RTO-16910B-DM2 that keeps getting stuck in 9th gear (F9 flashes). I have no active or inactive codes. if I reset transmission according to manual, it works fine for a while & then happens again. Any suggestions?

Mechanic's Assistant: We'll do all we can to help. Is there anything else important you think the Heavy Truck Mechanic should know?

It seems to only happen with a load of grain on.

When key is on, 2_0.9 comes on then switches to mileage. Doesn't seem to be any abnormal lights. When I cycle the Mode button, Diag 00 shows up. Doesn't seem to show an actual fault detected as per that link.
Technician: Daniel Wilson,

In the manual it says to press an hold the mode button for 3 seconds to select a screen and just pressing the mode button will scroll through. hold the button at Diag and it should bring you to a new screen

When I hold button nothing happens, it just stays on Diag 00.

Ok thanks for that. I just wanted to see if there were any other codes logged in the Engine ECM etc. It sounds like it might be mechanical with your transmission. Drain the oil in a clean container and look for metal/debris and anything that looks like grey sludge antiseize that would indicate internal problems. This can be caused by a faulty XY shifter or internal wear in the clutching collars which is unlikely for sticking in gear but check inside your filter if you have an external filter kit as well. Let me know

I did forget to mention we had a new inertia brake put on a few months ago. And had fresh filters & oil put in when the mechanic changed that out. Could it possibly have anything to do with that? When we asked the mechanic, he said it shouldn't .
