Is the lock up torque converter needed on th350?
I have a 61’ Chevy c10 with a 78’ 350 5.7L. With what I think is a th350(might be a th350c) automatic Transmission. While changing the tranny oil filter I found a plug with all the wires cut and nothing connected next to the speedometer plug on the right side and later found out it is for the lock up torque converter switch. I haven’t driven the truck because I swapped engines when I got it. Does the plug need to be connected and hooked up to a switch for it to run well or is it something I don’t have to worry about and deal with later? Is the transmission a rh350 or a th350c if I do need the lock up? ( no computer in this truck)
