Well, I found out some good news regarding my hydro change. I used TSC premium hydro fluid and have since put a dozen hours on it. I can't really notice any difference in the sounds of the tranny or gears like some others have mentioned. Some of them said they went back to a 'major' brand fluid and the machine got quieter, but that's not my issue.
The first thing I noticed is that the H-M-L shift lever doesn't stick any more and it changes gears perfectly every time ! I find my self actually using it more.
Many have posted that their tractor has a tough time changing those gears and mine did to a point as well. But not now !
I'm glad I didn't spend the extra many $ to get a 'major' brand fluid. TSC Travellers Premium works good for me !
