| The service information in my web page is a quick solution. I know it works. I did it to my '68 4020 and I have let it set for several months, pushed in the clutch started it and lifted the loader and steered lock to lock before letting the transmission pump turn. I know many others have used that information to make successful fixes. It converts an elbow to a check valve to replace the worn check valve that is deep in the transmission and hard to get to. Side console 4020 moved that check valve up high so if it leaks it doesn't drain the front cooler/reservoir. I have found some bulletins about side console but haven't added them to my web page yet. I plan to do that, I already have them scanned just have to work on the page.
