When it broke the time I was referring too, I was too new to Aods to fix it myself. I just know the tranny guy told me it was a clip. I know he fixed it in the car, so that tells me it probably was in the valve body somewhere.

I have also had the problem of shifting into 4th gear, doing the same thing yours is doing, just revving. The problem for me was once a broken od band, and the other time it was because the servo was not engaged into the band properly.

It sounds like your servo is not engaged from the sounds of it. Are you saying you found one of the clips that holds the servo in place to be broken? The servos can be quite hard to move in there.

Truth be told, if your transmission really has that kind of mileage on it, you are going to be chasing demons in that tranny forever. I would recommend pulling it and having it gone thru. If you have to get it going, you need to try and see why the clip came loose.
