I checked it just after I parked it, and the fluid is at the same level it has been since I got it. Which is to say, about 2" over full hot. The fluid looks great, and I've never seen any drips or pools of tranny fluid before and nothing has shown up since.

Just to clarify now after looking it over a bit, when I put it in neutral the car does roll back. Also, I do remember thinking the transmission was shifting pretty hard (between park/reverse/drive), but I had never driven a TH400 so I wasn't sure how much shock was normal. Also, I forgot to mention that the engine mounts are more like engine pads, because there aren't any bolts between the mounts and the block, but there haven't been since I got the car. And that's why it's been relegated to 10 mph test drives (and the 15 mph speed limit here on base).

I will post some pictures shortly of the drivetrain, or what I could get to, but they all seem pretty normal to me.
