CUMMINS X15
EATON AUTO 3RD GEN
On startup, all seems fine.
When shifted into and gear...
sa 3 spn 751 fmi 8
So seems to go and shift.
The manual makes this sound like a shifter issue, but wanted to know who's seen this before.
Thanks!

I’ve had FMI 11 SPN 751 before on my 2013. Is the truck up shifting and downshifting ok?

2013Maxx Thanks this.

So this just came back.
If the truck is in neutral, there's no error code. Shifting to any gear caused the error to return. -

That's what I'm wondering. It still seems to be operating correctly but I don't want to be far from a shop when it besides that it's done.
I've been told this can just be the shift controller that's there on the steering column and that's not hard to replace to replace. But I don't know.
I'm hoping Heavy chimes in.
