955 won't move

[mousedoc]

My 955 hydro runs, but won't move forward or reverse, high or low range makes no difference. It ran fine when I last shut it off, but when I restarted it a week later it almost sounded like I had the parking brake on (it wasn't) and moved a foot or so before I took my foot off the pedal. Then wouldn't move at all. When I checked the trans oil, it was foamy. I later checked the oil again and it's at the right level. The loader and 3 pt hitch raise and lower, but stutter when raising. Power steering stutters, but will turn the wheels. When I depress either pedal I think I hear a faint hiss. Any ideas???

The foamy hydraulic oil makes me think it is sucking air. Check the two rubber fittings on the main oil suction tube for starters.

Sorry it took me so long to reply, but I've been working everyday since I made the original post. I checked both fittings and they seem to be fine. Any other suggestions?
