Bought huge parts lot has rebuilt 350 transmission with tag labeled 18 tooth gear installed anyone know anything about this? Also have bunch of transmission gears including 7-8 good ab gears.

No idea what that gear is, but I bet Dan Roberto would. Congrats on your parts!

This might help,it's the gear that the selector hub engages with or rams into for F or R.

Also read this on AB gears and compare all of yours stacked against eachother.You might have the 2 diff teeth #'s? Diff topend speed?
I noticed this on my many trany rebuilds on various Odys over the years.
I also recommend drilling an extra 2 oiling feed holes on the AB gear plus if possible a gallery catchment/feed groove joining up the 4 holes.
This way it significantly draws in the available oil to all 4 holes instead of hoping it eventually gets there on 2 loners? Bigger Bullseye!

I think I will match this transmission up with my leckich big bore and see how she does. Thanks for the info.

Hey bug ---- do you know if the odd gear set was in the pre-recall trans or post recall ??
CO

Both me and hoser want to know that too.
Still haven't found out over all these years.
Hey Ridge can you do me a favour and mark your Input and Final drive shafts at 12 o'clock then turn the Input 1 full turn and see what # the Final turns are?

Ok so marked and turned in put shaft. 10 turns on input shaft gave 1 complete revolution on final shaft. Are these 10:1 reduction?

Was going through boxes of gears found ab gears one marked 32 tooth with larger 20 tooth gear with it. Other ab gears say 38 tooth on them. Anyone know anything on this?
