I have a an XUV550 Gator with 410 hours on it. It is my personal machine and i have maintained it religiously and It has not been abused. It is used on our family farm for transportation around the farm, fence repairs, etc. One day it got stuck in 4 wheel drive and would not come out...The lever was jammed. I tried to move it on the trans case but it was solid so I took it back to the dealer who informed me that the trans was "totaled" and filled with savings and gear pieces. I had them replace the trans to the tune of $7100...now of course I'm concerned that this trans is poorly designed and may fail again. A new gator is well north of $16K so we had to fix this one of course. Do you think there may be a better fluid to use in this trans than the recommended John Deere Hygard ? Any suggestions are appreciated !
