get lock up unless you want to kill your gas mileage

a non-lockup convertor will also build more heat. Lock up is definitely the way to go.

there is a lock up clutch in your trans that will lock your stall convertor instead of letting it slip to its stall rating. I dont know if i described that very well but thats the best I can do lol

Good try, but not exactly.

A torque converter has a clutch like (albeit smaller then) a manual. It is located at the front cover, towards the engine of the converter. Upon meeting certain calibration parameters from the ECM (for electronically controlled trans), the transmission is signaled to apply fluid through the input shaft to the torque converter clutch (TCC). This hydraulically/pmechanically locks the engine and trans input shaft together. This dramatically reduces heat and allows the engine to have a lower rpms for any given MPH, resulting in better fuel economy.

Unles you are strictly drag racing, you are best suited to go with a lock-up style converter. Most aftermarket companies that mak converters for the LSx market will only build a nonlock-up unit on a custom order. Off the shelf models will have the TCC.
