My first thought on the first pin (the double rolled pin) was that it went to the shifter knuckle linkage. However, I did not take that pin out. The finish on this pin is nice, no dirt, etc. so I am wondering if it should have gone inside the transmission where it was soaked in gear oil all these years. That is my concern and fear - that the pin goes inside the transmission somewhere.
Is anyone aware of a pin like this that would be internal to the transmission?
