I have disconnectrd most of my computer on my 81. The torque converter no longer locks up ( I think) I am ignorant as to the purpose of the lock up and when and why it should happen. Any comments would be appreciated

The lockup is designed to lower engine RPM at higher speeds. In general torque converters slip so as to keep the engine in a higher rpm band where horsepower and torrque offer a better throttle response. Now if you are highway crusing then the lockup OD lowers your engine rpms by eliminating slip usually through mechnical means.

usually its just a 12v trigger that locks the convertor. You could wire in a manual switch to control it for long freeway drives.
