Just got a 97 jd GT275 hydrostat with what looks like the k70 or k71 trans.Unknown hours. It takes 4.4 quarts of J20d low vis HY Gard fluid and a changeable filter [27 bucks- yikes].Runs ok but seems a little loud. Has anyone ever put auto-rx in there to clean it out? How long would/did you run it in clean and rinse phase? Anyone switched to synthetic 5w-50 afterwards or instead of Hygard? Thanks for the help.

I had a GT262 that was the same tractor, but with a fender shift TuffTorq 5spd manual. Nice tractor although I'll take a hydro any day for mowing service. TT made gear transaxles also back then. ARX shouldn't hurt since your hydro unit has a filter. You could easily use a HD 40 or 50wt in there. Joel

Thanks JTK. I think I'll try it. I'm going to run it for this season with the auto-rx and then drain and refill for a season and see what happens. I really love this thing!
