Hey everyone, new to the forum here! I have an 06 kubota rtv 900 that I’ve had for 2 years. Great machine, engine has 320 hours in it, rest of the machine about 1500. This machine isn’t a race car as we all know, but has always been a bit slow going up hills, 10 mph or so on decent 20 degree slope. I was out with my brother and we had a long uphill climb we did, by the time we go toward the top it was down to a crawl in 4wd in low. We managed to limp home and on my last downhill into my driveway it felt as though it was in neutral, it rolled very freely which ordinarily as you all know it would typically slow its self down due to the HST.
I had never serviced the transmission so I did the filter and fluid change with Napa filters and tractor supply traveler fluid. I fired it up and it moved in low, went up a small hill, then back down to the shop where it wouldn’t move any more.
I purchased the correct filters and fluid from kubota at Marshall’s machinery. Confirmed my fluid levels after warming up, still doesn’t move in any gear. I took apart the linkage and confirmed my fork is moving the gear selector. Confirmed the linkage is lined up in the transmission under the cover. Not sure where to turn from here. No metal in filters, none on the magnetic drain plug, hoses don’t seem to be collapsing, don’t see any rubber particles in the filter or fluid.
I suspect it’s something with the pump, when I jack up the rear of the machine I can turn wheels by hand while in gear, and they don’t spin at all when I get it throttle. The engine revs like normal and sounds like it always has.
Where should I start looking next?
Thank you all for the help, hopefully I can get this resolved.
