Additional Notes: Beginning in 2016 the number 7 check ball was eliminated, also the Lube Override Enable Valve was removed. Always check and see if the Lube Valve is present to determine if the number 7 check ball should be in the Valve Body or not, it appears that some of the early 2016 valve bodies must have still had the valve and check ball in them.
