Well....I think I found the problem....I got it all back together, after looking everything over and trying to fiquire out what was happening, only thing I could come up with was the trans was sometimes getting into forward and go-behind at the same time, stripping the reverse gear. I looked at the linkage that operates the direction. looked like it was just barely pulling it into forward position. Maybe when I am on rough ground, it was getting into both gears at the same time due to the bouncing around. I tightened up the spring tension on the linkage, and used the trim on the radio to make the servo pull the shifter out with more pressure. I thought about putting a wheel collar on the shifter shaft to lock it in forward, but I do use reverse once in a while. We'll see what happens, it works now, time will tell........Coop
