ECT = Electronically Controlled Transmission. When activated, the trans shifts at a higher rpm. -- Toyota recommends leaving it off to improve fuel economy" When to use your ECT Using your vehicle’s electronically controlled transmission, your Toyota’s engine is able to shift at higher revs. That being said, a good time to use this function of your engine is when you need to accelerate quickly, such as when merging onto the freeway. Acceleration is noticeably quicker with the Electronic Controlled Transmission on, however it should be noted that it significantly decreases your vehicle’s efficiency. So while you could leave it on and experience the influx of power all of the time, if you’re looking to save at the gas pump, we wouldn’t recommend it. **On the Avalon, the ECT mode buttons toggles between normal/economy and power shift patterns.
