[Gee]

I had the same issue recently with my flm HV Maxx. Wasn't the diffs that were flipped it was the transmission was installed backwards. Mine was a little more obvious. Going forward made the maxx go forward but it wasn't as fast as normal and the brakes were instant reverse as fast a forward was normally. Like coming back right at you jump out of it way fast. But I couldn't hit the brakes when it shot past me into the fridge because pushing forward made it go faster.
