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.

I don't know why an MR2 auto trans would be any stronger than a 6gc auto trans. They were both mated to the 5SFE.
