I am getting ready for my 50 hr service and I know there is alot of talk out there about which fluid to use in GC2610 trans. The dealer I purchased from uses kubota UDT in all there Masseys. It seems to work fine. I am looking for input from others out their that used other than Permatran III . I am looking to use Shell Spirax fluid which is a 10w30 like the permatran and according to Shell it exceeds the permatran specs. TSC also has Mystic JT5 which reads to be pretty good. Thanks
