Okay, well I fixed the u-joint problem I had earlier. It turns out that my C4 had the wrong slip yoke on it. I picked up a used slip yoke and all is well with the u-joints.

Next problem with my transmission is the fact that the thing doesn't want to fully engage park. I've discovered why when working on my u-joint problem. It appears to me that this transmission may have been pulled out of a console shift car. Follow me from the auto shifter to the transmission...the auto shifter drops through the floor and connects to this z-bar, this z-bar travels towards the front of the car and connects to a "little arm" that rotates on an arc and dissappears into the transmission. This "little arm" is incorrect for my car. I looked at a stock 66 up on a lift and got a good look at a correct setup. The little arm in question on the correct car is orientated up and down when the car is in park. On my car, the little arm is about 3/4" shorter and is orientated left to right when in park. I believe the little arm needs to travel downward on its arc a little farther in order to engage park. As you all know, the auto shifter linkage travels left and right, not up and down, so it can not travel the rest of the distance to fully engage park consistently.

My questions are...

1. Can I just swap out the little arm with the correct arm for my car?
2. Where can I get the correct little arm? Is it something I can order or do I need to find a donor car?
3. Has anyone else encountered this problem?

 

I just got my car back from the tranny shop and my tranny guy said the C4 that I have in my car is from the 70's and the linkage was messed up. He got it to work without any problems and he fixed the leakage associated with the messed up linkage. He only charged me $20. Can you believe that!!! Take it to a tranny shop and let them look at the linkage it could be a quick fix like mine was.
