i'm trying to id my tranny but i cant find a discription for it. the id reads 67mm203N...?

 

Moved your thread to the transmission forum for better readership. Hopefully you will get an answer soon. Good luck.

 

Can you post a pic of the ID tag? Might be helpful...from what you have given 67 would be the year and mm would be what make it is and the other numbers are the corrosponding vin numbers. I don't recognize the mm...anyone? B is Buick, O is Olds, I'm no expert someone else chime in...
