I don't think that's exactly right. There are sensors from the stock ECU that you lose, like the speed sensor, throttle position sensor, engine rpm etc. Without these, the tranny has no idea what the car is doing. What are your shifts like? Does the kickdown and everything else seem normal? I guess the transmission operates in some sort of "limp home" mode since it's not receiving signals. At any rate, it can't be the best for performance or reliability, which is why I wanted an ecu in the first place.
BTW according to the shop manual K-214 short TAT and GND to read trouble codes.
