There are 10 variants to the M9000, can you give the tractor serial number or the exact model variant your working with?

Excellent, your model is a M9000DT-CAB

Start from the top and work down, checking all of the linkage.
If something doesn't look right or move right get a picture of it and post it and we should be able to help you figure it out.

thank you! I am down to trans cap. All the linkage is free and tight, seems to working as it should. Going look under the cap in the morning. Is there any tricks to pulling the cap?

All I can see is watch for these parts:

And you'll need to make sure this aligns when you put it back together.

I agree with NIW. If your linkages are ok, thinking shift parts inside. Pull the boot up and make sure no shift guides are stuck. (Never been in this model). I do see a Bowden cable. If the casing has any break in it. It'll lock up.
