i have a full manual 4l80, no electronics...just one wire to still be able to lock up the converter

Is there any way, or pin etc that i can still have my tc lock up automatically or am i just going to have to put in a toggle switch and lock/unlock manually every time?

If you wanted to do some electronics cobbling you
could make a fairly simple push-on, brake-off one.
I bet there are people making little boxes for more
sophisticated (TPS,MPH,brake) inputs.

Order a B&M lock up switch for a 700R4 with electric speedo. It's speed controlled and adjustable. You will have to splice the lockup wire into the 80E plug and wire it into the VSS on the 80 but there is no reason it won't work.
