Alright so I have a 700r4 with a full manual valve body. If you take off the trans pan, there is a metal piece with several teeth, kind of looks like a circular saw. This piece has a hook that dangles down from it and is connected to the manual valve piston that can move in and out of the valve body. There is a piece that bolts onto the valve body and is placed on one of the teeth of the metal selector and I'm not sure which one it is. My car won't get into first gear. In park it won't move, and in any of the other gears it just rolls back, I'm pretty sure that's what the problem is. So if anyone knows how this is set up any info would be aprecciated, thanks.
