TH350 overdrive ID
I have a TH350 Trans in a hotrod which has an electric plug-in on the drivers side. As I understand; that would make it a 1984 or newer unit. I presently do not have anything plugged into it altho I do have a pigtail to plug into it. Does having the plug-in make it an overdrive unit? If it is an overdrive unit; how would I wire it to utilize the OD?
Thanks Glenn, it’s believed to be a Gen 5. 454. I’ll see if I can snap some pics of the stamped and cast numbers and post them here. Maybe we can define the year and model
