Important note for transmission modders: Some transmissions use a pwm signal to give different duty cycles to the TCC. This allows some slippage. I found an article that explains how to do it properly although you will have to modify it to get the on demand lock up:
A604 transmission:
Chrysler, Plymouth, and Dodge Four-Speed Automatic Transmission Torque Converter Disabling(not really disabling but disabling the slip)
Adding a manual switch will actually
reduce wear on your TCC and reduce heat build up in your transmission.
Christ, is this what Cara has?
