Ok, after cleaning some of the transmission I found this::: I'm assuming it's the area where the Reverse Idler shaft lock pin would be?? Welded up?? See picture. Is this case a Lost Cause now (** If they have issues*) Removed main shaft , looks a bit "Worn",...Thoughts? Also the Syncronizor Drum looks bad. The 2nd gear side it is Missing the two "Tangs" as part of the ring? See pictures. Thank you, Oh I have not figured out how to remove the " Rear Bearing support) #18 on GM Transmission 7-7. Any hints? Todd Added: the Manual calls those "Syncronizing Cones" .
