Took the valve body off which was surprisingly easy. My goal was to inspect the accumulator switches because of a lead that I received about my reverse making a whistling noise and/or not having reverse, or very little reverse. Its been going on a few years now since the reverse has been problematic, but I did not get a rebuild because one day the reverse was fully functional. I decided to check the valve body and they only thing I did find was 2 beige looking o-rings around a plastic part that looked like they needed replacing. Both had a diagonal cut, maybe they are like that on purpose, I'm not sure. But they were shrunken and allowed the part to move a littler too freely so I replaced them with new o-rings. I have not noticed a difference in the reverse and I think the whistling noise may still be present
