Are the check valves from the 300 series tractors interchangable with the ones in my 120? i am in search for some new ones as mine are leaking oil from the buttons on top. i seen one pair without the buttons on top and wondered if i could get away with running those so i dont have to worry about the leaky buttons? Thanks for anyones help!

I think the 120 was the first JD to use the Dana/sundstrand transaxle. All the 300s up to the introduction of the 318 used the same setup. The later 140  ser. 30000 and up also used the Dana setup. 

  I think you can get those valves and other transmission parts from a Sundstrand dealer new for a lot less than JD sells them for. Somewhere I think I saw that new  valves are only 50$ ea when purchased this way. I have a 314 that has had them replaced at one point. My 317 has one that sticks and the button is chewed up where it looks like someone put a set of pliers on it to pull it up.
