Same Speed in all gears

[AbacoJack]

I have a M7060 with a 12 speed transmission. Gears 7-12 work fine. but the speed in
Gears 1,3,5 are all the same at 2.65 MPH and Gears 2,4,6 are all the same at 3.6 MPH. Any Ideas what could be the issue? Fluids are all good..

New problem- or new to your tractor?
Seems to be limited to low range so I guess that's something to tell the dealer if it gets to that point, hopefully one that's familiar with that transmission.
What confuses me is I think it's the same 6 gears in both ranges (12 sp) and that would eliminate a shifting linkage (in my mind) , and high range works fine.
This, based on my m9540 12 sp.

Something is not right here.

As I understand your statement, what you are describing is not possible.

What am I missing?
