I hope everyone is doing OK. What is the best way to determine if a 4-speed Muncie transmission is original to a 1967 GTO? I think I can get the PHS documents for the car if that helps. What are my options if I CAN get the PHS docs, and what are my options if I CAN'T? Thanks for any help?

I don’t think the VIN stamps started on the transmissions until 1969

seems to me on my '66 it's the last 6#s of the VIN, been a while since it's been up on the lift for me to see

My '66 Had the last 6 of the VIN stamped to the top front edge - next to the bell housing.

Your partial vin should be stamped on the top of the tranny but nearly impossible to see unless you pull the tranny . On the passenger side near where the tail shaft bolts up you should see some numbers and letters . See my pic . Get that for us and we can tell you if your tranny is original to the car .

The photo you posted shows the trans assembly date stamp for a Muncie, correct? Is the VIN stamp close to it?

No , the vin is on top . Almost impossible to see unless you pull the tranny .

My original '67 Muncie with the last seven digits of the VIN. Looks like the guy that did the stamping must have partied hard the night before.
