Got a 5088 got around 7000 hrs iv only owned it about a year so haven't done much but issue I'm having is under a load it acts like it pops out of gear I was runnin med in 1st gear and it did it like 4 time sentury light does come on push clutch and it will move again now I droped to low 6th and made another round and it didn't do it in that gear. But I went to go down road in high range 6th and it did it but droped to 5th and got some speed then went to 6th and it was fine. The fluid was bout1 gal low I added some hopein this would solve issue didn't seem to make any diffrence. Also goin down the road bout 18mph sounds like a press relife valve under my feet is relesing bout every minute traveling down road now in field I don't hear that
