A small update of concern: last night I was driving home from a mountain bike race and getting heavy into the throttle a bit just for fun. I had been driving for about 7 miles when I realized I had the car in 3rd not in "D". I think at this time I was likely going about 55-60 mph and I shifted into "D" no problems. About a half mile later I was taking a big sweeping exit ramp so had let off the throttle and felt the transmission bumping into and out of gear and noticed the HUD showing it shifting into and out Neutral. It did about 3 times each one about a second apart. I shifted back into 3rd and then into drive again thinking the selector may have been finding a false neutral. Everything was fine from there on out. The shifts weren't overly harsh or anything but it scared the crap out of me.

Does anyone have any thoughts on this or a similar experience with a false neutral? Hopefully a fluke but I'm a little wary of the Transgo install right now...
