Locking torque converters have a clutch inside them to eliminate slippage, which reduces temperature and increases mileage. There are no "manual locking" converters, the clutch is controlled by fluid signals from the transmission. You can manually control the lockup by playing with the wiring.

The easiest way is just to put a switch between the wires to the A and F terminals on the ALDL connector. Turning on the switch then will lock up the torque converter in every gear except first. If you want automatic control without the computer, there are a number of kits on the market that you can buy. If you're a little more adventurous (or cheap) you can modify the wiring harness inside the transmission to do the same thing for nothing.

You NEED the locking converter on the street. On an '84 you should have a TCC valvetrain in the VB. This means that you can control when L/U accurs through spring changes in that area of the VB. Then you can wire the solenoid on all of the time.

The only benefit of a non-lockup is it doesn't have the clutch to go bad. Lock-up reduces rpm going down the highway. Normally a torque converter slips all the time, wasting energy(efficiency). Your tranny will run cooler and you will get a bit better mileage.

I have a switch to control mine..i have the option of off (no lockup period) auto(let tranny decide) and ON (force lockup)
i dont use the lockup around town..its very nice..normaly right after the 2nd gear shift the converter locks up and lugs the engine..also when the converter is locked up and you stab the gas the car will jerk like a stick shift. when its not locked up the rpms climb a bit and the car will accelerate, its much smoother,another benefit is yout dont have to nearly floor it to get some power to climb a hill.

How would you go about making a switch such as this?
Also, i have been smelling burnt tranny fluid when at WOT, what can cause this?

Something's not right then, Corvettes might be different, but I don't think an 84 700R4 shouldn't be locking up in 2nd. TCC lockup was still partially controlled by the valving inside the transmission in early 700R4's.
