Hello everybody, I just acquired a 1973 GMC 3/4 ton long bed truck. I have a couple of questions about it though. Trying to figure out what transmission I have. It is a 3 speed manual with a granny gear. The shifter goes all the way left and up is granny low, straight down from there is 1st up and to the right is 2nd, straight down is 3rd and all the way right and down is reverse. I thought this was a SM465 but I am being told by others that it isn't.
from N.E.
