Case 580L backhoe transmission problem

I used my backhoe loading dirt all day and stored at end of day. Next day cranked and it was shuttering in any gear I put it in. It also had to be shut off to go between gears, much like a manual transmission with a cluch con tuning to engage. It will move in every gear, forward and back but is still shuttering like it is getting engagement and not at the same time. I am new here and could sure use some help. Thanks
