What information is needed by the ECU to decide when to shift?

So far I assume that these are definitely needed:

Throttle Position Signal
Tach signal
Speed Sensor
coolant temperature (for limiting rpm while engine is cold)

Can anyone think of anything else that would be needed by the ECU to operate the transmission.

Caldina = 4WD
Celica GT = FWD

I already have an auto trans.

As far as your research is concerned, what led you to that conclusion? If it's the lack of an auto ECU for the 3SGTE I've already overcome that issue. I'll be running a standalone for the 3S and the stock ECU for the trans.
