My '67 Fremont built 442 has "S4" as the transmission code on the Protect-o-plate. Can anyone help determine the meaning of the code? Thank you!

S4 is the mystery transmission code on my POP. My axle code is PS1 (Pontiac 3.55/Open). Still looking for the S4 transmission code.

 

Check out this thread: 1967 Oldsmobile Cowl Tag Information Sheet - Page 2 - ClassicOldsmobile.com

 

The cowl tag info looks right but my question regards the Protect-o-plate. I was able to decipher all of the info (Interior, exterior, production month and axle code) on the POP. The only remaining question is the transmission code S4. Any help??

 

F-85 4-4-2 Helped me find the reference to the S4 code. Last Line Reads ""S4" Used on 4-speed Synchromesh" Thank you!!!

 

Oh that's nice.

 

I am not an "Expert" but I have fully decoded my POP, here is what I believe is an accurate breakdown. The top portion is just the original owner Initials/name and address along with a delivery date of 4-13-67.

The lower portion is as follows
First Row is "980" - Black Bench seat "NN" - Burgundy Mist Upper and Lower Paint color (no vinyl top) Full VIN - matches the car
Second Row is "V213368G" - 442 engine unit number "PS1" - Pontiac 3.55 rear axle "N" - April Production Month
Third Row - "S4" 4-speed Manual Transmission "01100" Power Steering and Deluxe Radio
Please share any thoughts on accuracy of these findings. Thank You!
