Default Reassembly: D16 s20 trans countershaft too short?

My transmission case was leaking so I pulled it out to reapply the seal, but while I was there I figured I'd check my bearings so I pulled the shafts out. I found the countershaft bearing (one with the rollers) slightly raised so I tapped it back down. Now I'm reassembling it, it seems like it's too short to reach the c-clip. The c-clip now suddenly won't fit onto the groove on the bearing, it looks like it's 1/4 inch too short. Any ideas before I replace the whole trans?

You have to lift it back into place in the case. If this doesn't work, try turning the transmission over and bouncing it gently over a 2x4 to "encourage" the bearing to snap back into the c-clip.

What do you mean by lift? Like pry the bearing upwards through the c clip hole?

Yes, but be careful not to pry too hard because you may damage the trans case.

Don't pry. Flip the case over and lightly drop it onto a phone book. That will seat the shaft into the case and the snap ring will close.

I suggested that too I have run out of phone books, so I recommended a 2x4 instead though...

I've tried it all, didn't work so I picked up a used trans. I opened it just to see what went wrong and here's what I've found.

Used trans I picked up has the gears lined up pretty flush.


My original trans is off, counter shaft is pretty low which is probably why the c clip wouldn't lock on.


My original trans, the counter shaft bearing was walking out when I first found it, so I tapped it back in flush.


The used trans actually protrudes out a little bit which is probably why the gears are even.



So now my question is, how do I raise up the counter shaft bearing without destroying it?
