555A no movement
Hello all new to the site looked through about 26 pages and searched for good hydraulics good trans pressure. But, no movement. It's a highlift tracks. I started with the transmission filter and trans oil check. So what happened was I pushed some trash into a hole and back up to get a few more little logs, put it in neutral and went to throw a few little pieces in, got back on and put it in forward 1 didn't move.

Look for the simple first... May just be your shift linkage has come undone.

So the shift linkage as in I can move the shifter to forward and reverse and see the linkage move under the floor pan. Also when I move to forward 1 and reverse1 the motor bogs down. I won't be back at the machine until Monday august 31 2023.

Ok I check linkage and didn't see anything loose or disconnected. When I love the levers, it moves all the way into the two blocks on top of the transmission.

Re: 555A no movement
Checked the linkage everything seems to be moving correctly and fast enough in and out. I did start it let it run and warm up to operating temperature, hydraulics are great, still no movement but I did notice as I was moving through the gears usually I use the decelerator pedal, this time I just went through forward and reverse shifting 123 forward 123 reverse. It goes seen like I have a bit of something motor bogs down a bit but, no movement. I did see there are summer screens located towards the back of the transmission pick up tube I believe it was called. I tried to find it in the manual. No luck. I also went through the manuals diagnostic as far as I could before I needed to check pressures. I believe that will be my next step unless I can find a savvy person in south east Missouri.

I also lost forward and reverse on my 555. I also had gauge in white and steering wasn't great at all. So I did as you did and pulled the suction screen out clogged except about 2"x3" cut out cleaned it off and out a d put it in the sonic cleaner for a bit
and also changed the transmission filter under the seat. I proceeded to clean and wipe out more of the bottom and discovered a roller bearing what at first I thought was a dowel, then found two more and another roller bearing. I went to the tool box and grabbed a magnet and found a big gland nut and also found a spacer round and flat.
