Electronically Controlled Transmission/Transaxle
WARNING: This page is about a different car, the 1997 Lexus SC 300. However, it is still accessible from the selected car via links, so may be relevant.
This system electronically controls gear shift timing, clutch and brake hydraulic pressure, and engine torque during shifting to achieve optimum shift feeling. A shift lock system is also incorporated to prevent possibility of incorrect operation of the transmission. The transmission ECM and engine control ECM are integrated.
