    probably some rocket scientist thought that the parking gear was a means of stopping at 10 mph... (The PO's of my burb did).......... I had the tranny guy fix a leak, so I got him to fix the parking problem while he was at it.... its called the parking pawl or pin IIRC.... I don't think it is very hard to replace...

    If you take the pan off it's hooked right to the shift arm (inside). It's not real hard to replace.

    it's almost definately your parking pawl. if you take your tranny pan off, let all the juice run empty, it will be on the drivers side of the tranny, up against the case, towards the back of the tranny. there will be a long rod that pushes a peice of steel into the rotating drum of the tranny, making it stop. somewhere something will be broken along these lines.. maybe someone else can be more specific or find you a picture, but im pretty sure up to this point..

    I have the exact same problem with my th400. the end of the rod that holds the parking pawl in place was broken in half. so I replaced it, but it still didn't fix the problem. I asked the guy at a local tranny shop, and he said that sometimes the plate that hold that rod in sometimes gets worn down, and that can cause it to not push the pawl far enough, and not hold in park. so I got one from him, and I'm gonna replace it this weekend, see if that fixes it. but if you're gonna tear into yours, you might wanna go ahead and replace that too, while you're already there, just to be safe.

    The rod could have a broken spring which would not allow it to engage the parking pawl fully. The rod w/ spring should run $5-$10.

    Look in the tech articles forum, at the shift kit install thread. Has a buncha pics, and IIRC says something about the parking pawl.
