Big Block/A-518

Well what do ya know. I looked at the plugs on the two units I have and the 89 one has a two wire plug(non-lockup) and the 94 one has a three wire plug(lockup). Apparently I did not know my *** from my elbow about these things. This situation suits me fine, I'm using the non-lockup unit in my 440 Duster and the lockup one is going into my 87 D-150 PU truck behind a 318. I know I'll have to remove the balance weight from the torque converters. One thing I'm wondering about is the thing about making them shift automatically. Are you guys refering to shifting into overdrive gear automatically or shifting at all? I guess I'm assuming things here but, the gear shift lever and the downshift (kickdown) lever are identical to a 727 so, dosent that mean that the trans will operate like a 727 and then shift into O.D. once 12 volts is fed to the correct pole and the other is grounded, or are you saying that these things will need a computer to shift at all?
