On the shift linkage lever, that one that connects to the shaft that goes into the transmission, there is a pin that holds the lever onto the shaft. I believe I have the found the cause for all my transmission woes through this pin. In my transmission it has sheared off, so that the lever spins 360 degrees and nothing is holding onto the shaft. I have another transmission I bought used that I was going to rebuild. For now though, it seems I can take the pin from the tranny to be rebuilt, put it on the tranny thats installed, and test to see if it really was just the pin. But how do I get the damn pin out and then back in?! Or where can I find a replacement?
