Thanks for the prompt response.
To be clear I think the pilot spool stuck at some time while I was plowing. Low and medium worked fine when I started. It was only when I downshifted as I was finishing that I noticed the problem and parked.
Will a destroyed clutch pack still periodically engage?
I'm guessing roading it back to the barn was a bad idea as if a clutch was stuck- the working clutches overpowered and forced stuck to slip.
I will go through the spool valve. I wasn't happy with the fit of c-1 I got while in the field. I agree that something got into valve pack and rest are suspect
I read in my service manual that steering was on separate circuit- does your comment imply steering can impact rest of system?
How are the a auxillaryv hydraulics tied into clutch pack and why would they only work in high?
Thanks again. I've read a lot of your posts and have found them very informative.
