Drain plugs are later issue from the M22 normal for 69, should say Lisle Magnetic 2 ( or 3 ), plus the synchro dog teeth have some heavy chipping especially on 4th gear, and 1st JMO

The '9' signifies the model year, which would be 1969. Since 1969 Camaros were produced late into the fall of 1969, you would need to cross-check the VIN for a rough production date. CON VIN shown on that trans is 19N513117, so if that is an early production 69 Camaro, then the trans was most likely built in August of 68 and the suffix letter would be missing. If it's a late production 69 Camaro, then it was undoubtedly built in August of 69....and should have the letter suffix at the end.

Posted that ebay listing in the CRG Orphans section on the 11th, no replies so the car probably isn't in the database.

Since I'm not up on 69 Camaro VIN's, I did a little more research. Colvin's book says that 69 Camaro production numbers began with 500000, so 513117 is pretty early production. Hence, it's a safe bet that the trans was indeed produced in August of 68 and would not have had the letter suffix.

It's important to find out exactly what kind of replacement gears, materials, etc. that this guy used in this trans. A lot of chinese junk out there. In my opinion if youre going to spend that much $2800 you might as well get one from a reputable source. I recomend you contact Craig Wright at "The Wright Connection"

Send me a PM and I can give you his phone number. He's working on my M20 right now! And he completely rebuilt an M22 for me back in 2007 which I've had zero issues with.

Pretty sure they are original GM gears, they all have dog wear, plus after market gear sets are a darker colour. The hubs are GM originals, no body produces that 3-4 sleeve with the thicker rib on back 3rd gear side, plus you can see wear the forks have marked them.

you guys are an incredible source for knowledge. I Thank You so Much. ROB

Book by Paul Cangialosi , How to Rebuild and Modify Muncie 4 Speed contains lots of info about most anything M20,21, or 22 including stamps and identification .

Maybe it's been noted here before, but the VIN is from 1968 year production and the trans assembly date is from later 1969 year production. So, either the VIN or the assembly stamp is re-stamp correct? If so, my vote is the assembly stamp. Wish I could read the casting date on the case.

The "9" in the assembly date stamp is for model year of car. The "9" was used throughout the entire '69 Camaro year.
