Hmmm.. Looks like the original suggestion from way back in Dec. that my drive shaft roll pins broke might
be the answer to my gear loss after all. But when I twisted it, it seems to engage the tranny, so I didnt think it was that. But I just noticed the rear driveshaft collar slides back and forth on the stubby shaft it connects to at the tranny. I dont quite understand why it engages when rotated, but I can see the edge of the pin hole in the shaft so I know its broken.
So now the question is, which is easier, sliding the engine forward or the rear end backward to get that shaft off far enough that I can remove the pin? I cant get the holes lined back up to knock the pin out, so I think I have to pull the shafts apart to get at them.
