Its most likely the brake light switch, also connected to the steering column. It controls the Torque Converter Clutch, and when it is out of adjustment, it will not engage upper gears properly...The computer gets confussed and tries to protect the transmission.

What does a 4l80e transmission wiring diagram for a g30 van look like

Unfortunately, it won't shift right without the computer. The computer is what commands the shifting patterns. Even if you put the computer back in, it won't shift right because you have remove sensors from the engine. You'll have to replace the transmission with an older one, that isn't controlled by a computer.

You could just have the dealer use his key code and cut another key for you. If you don't want to go that route, unplug the battery for 5 min, and unbolt the air bag. It should have one or two connectors once you get it off.
