Lockup to non-lockup question(s)

Just a FYI. If you find a A-500/42RH/42RE you might not want the 42 RE. The 42RE is controlled by the engine/trans computer in the OE installations, so it requires more control systems to be used as a "addon". The way you can tell is by the electrical connector. The A-500/42RH has a electrical connector with only 3 pins (not the connector for the neutral safety - backup switch). The 42RE has a connector with more pins. I forget how many.
