badhorse800 0 #1 Posted May 25, 2015 I have a 1973 12 automatic that I recently bought, I needed to move it and i could barely push it, so I opened the screw valve (only about 1/2 a turn) so I could push it, now with the same valve closed it to its original position it is still easyeasy to push, is this normal or did I do something wrong, if so how do I fix it?

nylyon-(Admin) 7,130 #3 Posted May 25, 2015 You'll have to get it running to test the trans. I had a C-120 which behaved similar, and it worked fine. Share this post Link to post Share on other sites
badhorse800 0 #4 Posted May 25, 2015 OK thanks, right now I am figuring out a wiring issue to get it to run, but I am almost don't with that Share this post Link to post Share on other sites
wheeledhorseman 573 #5 Posted May 26, 2015 I have noticed this with my Sundstrand hydros as well. Once you run the hydro afterwards it returns to being 'solid' again but I don't think it is a good idea to push the tractor about with the valve closed again just because you can. I suspect it has to do with releasing some of the oil in the otherwise 'sealed' system that exists between the pump and motor. Share this post Link to post Share on other sites
badhorse800 0 #6 Posted May 28, 2015 Well i kindakinda leaned up against it while I was talking and I almost kinda fell on my butt, I thought with putting the screw back in position it wouldn't move Share this post Link to post Share on other sites
