3 speed 4x4 trans. id
I have a 1970 3 speed 1/2 ton 4x4. Can anyone tell me what type of trans this is? I have seen info that chev used car 3 speed with a special adapter for the 205 case. Also some guys say it is a 3-speed Tremac transmission .
Thanks T-roy |

I want to say it was an SM318, but someone one here will know for sure. Sorry, I couldn't find the specific info in my GM info.
