Okay.. the verdict (I think) is in..
The semi-adept mechanic says that the problem was a small "pin" close to the tranny... He says that it was the pin that holds the shifter linkage to the rod that goes in to the tranny..
Est. ~450 to R&R, with labor incl.. Says done by Tuesday.... We'll see...
Keep your fingers crossed, and hope this guy isn't COMPLETELY dumbfounded..
