Issac,

Go to the first post and follow the link to the Toyota forum. Read the first post there and it explains it better than I can. You need some resistors switched to your ECU or TCU that make the computers think they are still connected when you have bypassed them. Then they won't "throw codes"

This requires some relays but it's not rocket science and it should work on any solenoid controlled tranny. You might want to check the coil resistance of the solenoids you are working with but I bet it's not critical. The performabuilt people could probably tell you.

Another trick he talks about is a black box which is really an automatic ecu resetting black box that removes power from ecu to erase the codes. This only works on OBDI cars as far as I know because the newer ones, OBDII, have built in flash memory. Possibly tuners know how to erase this. Someone correct me if I'm wrong.
