the 5488 started to click in 5&6 gears in all ranges,the rest of the gears sound normal. I was planting with it and it wasn't pulling hard, just go down the field and it started clicking. I have a couple of days to go yet, I have stayed away from those gears for now, which really sucks on the road!

 When I get done I want to pull the cover off the side of the tranny, any idea what I could be looking at?
