Hey guys! I just bought a 69 Z28 and I wanted to see if you could help me out with something. While having the Engine (number matching) worked on, I took photos of the transmission so that I could research to see if it was original. The assembly date code reads as follows P9R10AE. It's the E at the end that is throwing me off. I'm not sure if that means it was an exchange??? What I can assume is the partial VIN also doesn't match anything on the car it reads 70Z140801.
If anyone could fill me in on this transmission or the coding I would appreciate it.
Someone will correct me if I'm wrong but the "E" stands for Eaton.
The vin is not right, it should start 19N------. Never seen an E after the transmission date.

The "E" is discussed in this CRG thread: http://www.camaros.org/forum/index.php?topic=1923.0
As for decoding the transmission, it's not the original one to your car. It is a Muncie M20 4-speed transmission that was assembled on October 10, 1969 for a 1970 Chevelle or El Camino. :)

The transmission stampings are not an original factory stamping. Characters are not even close to what they should look like. Someone has stamped this case.

That trans is from a Fremont built car... it has a Z in the Vin...
