I finally got a good look at my transmission and I beleive it is not the original. The car is a 69Z but the the trans code is P8C18 which I believe is from a 68....

Actually can anyone identify if this is a m21 or m22...?

Here's all the numbers I found.
3884685 Driver side
3925660 Driver side

P8C18 Passenger side "something unintelligble stamped here at end of series"
3088336 Passenger side
18w308216 Passenger side

I believe it is from 68 March 18th. What I'm also not sure of if it is a true Camaro transmission. Any help would be appreciated.

Definitely not a Camaro transmission, with the plant code being W in the partial VIN.

[Straight-line-69]

W = Nova,..I think.

I read that the first number in the VIN stamp denotes the model of the car. I haven't been able to determine what number represents a Camaro.

[RamAirDave]

The partial VIN only give some info on what it came out of.

1 = Chevrolet
8 = 1968 model year
W = assembly plant code

I dont know off the top of my head which plant that is, or which cars were built there, but camaros only had L or N for the assembly plant code

W= willow run michigan, they slapped together the Nova's.

The trans was assembled on March 18, 1968, and was originally installed in a 1968 Nova at Willow Run.
