Justin, have you replaced hyd filters? check suction hose off back of pump going to resivoir, make sure clamps are tight, this hose is steel braided, I loosen clamps, should be four of them two on top and two on bottom, turn hose a half a turn, you will need a waterpump plier. Is steering sluggish when you start it up, if so this would be the first place to look, the only places I see check valves is on bottom of hyd pump, and one on the bottom of each hyd filter. As far as shifting, nature of the beast, pivot tractor to a hard left, on r/h side of transmission, you will see four shifting forks, the ones closest to you are easy to get to front ones kinda a pita to get to. Get a blow gun and blow all the snit off, lube the heck out of them, I mean alot, walk away, come back a hour or so, have someone up in the cab and move each one back and forth as you lubricate, they will loosen up, p,s poor desighn, shoot me a email with contact #, worked on alot of these girls, I would look at back of transmission any visible leaks, I argee withh 1156 Versatile, I would check all above, will give you a call, Scott. Thinking about this again, transmission lubes it self, you have a suction screen or r/h rear of transmission, check clamps make sure they are tight, might not hurt to pull screen, need to drain tranny to see if its plugged. I am wondering if all above is good, you have a bad pump on rear of tranny, can be removed from rear, pivot tractor to get aceess to, I would take it apart ar have a hyd shop do it, need to think about this more, Scott.
