L2250 shifter failure

I’m starting this thread to placeholder so when I have power for the phone I can actually search threads.

It seems the high - low transmission shifter is stuck in the lower 4 gears from this “shuttle shift” design…..

I know my way around search engines but, this time I’m falling on my face with less than 10% power as I go into a Dr. Appointment.

The shifter moves smoothly and with no errors but, the tranny does not increase in speed from transfer.

Can one partially disassemble the transmission area under the sea to see about the status of the shifter fork?

So I made a mistake in thinking.

Here is the link to my post that I had planned to put in this thread.... instead I'll just share this jump to my post over in general repairs....

How to gently remove the top of the transmission on L2250?

i've been to and downloaded the pdf of the user/owners manual for this puppy. 1) after a serious pressure washing the decades of mud buildup, got it clean enough to see and break the bolts and nuts loose. 2) got out a chisel and hammer to test if thats what it needed to pop that lid off the...

I posted a reply about taking off the Hydraulic Cylinder cover with your post over in REPAIRS.

Once you have the cover off the shifter is visible - my guess is the linkage parts down in the bottom may be at fault. An interesting thing is that there are TWO forks.

Below is the fancy shift linkage - zoom it up to be readable. Its complicated to acomodate the shuttle, blocking 8th gear from F-R shifts. Best luck, Dick B.

p.s. Your good efforts so far make others want to help

These tractors use a single shuttle lever for going forward or reverse while in 1st thru 7th - but R is blocked in 8th. WSM page below shows the power flow.

The shuttle parts are forward of the Hi-Lo section. Its a lot to digest in one look, especially since the drawings don't clearly show how or what the second Hi-Lo shift fork engages.

Any chance your hi-lo actually works ok in gears lower than 8th?
