Hi, I’m working on installing a new American Autowire harness in a 1964 GTO. I’m close to completing the job and I have a question regarding the transmission connection. The question is should I get the parts and harness to wire the circuit up or run it without the kick down feature. I’m not familiar with this style transmission. There’s a switch mounted on the carburetor linkage and a connector close to the shift lever on the driver’s side. Any input on this would be greatly appreciated. I attempted to unplug the connector near the shift linkage but it wouldn’t budge. The switch at the carburetor doesn’t look too healthy either. I’ve researched a little and think this may be a two speed transmission with a locking converter. I quickly checked the pan and it’s square with a corner missing like a TH350 but the shift indicator shows P-R-N-D-L on the console.
