What is the function of the ECT in the old Camry?

[Mark]

The ECT in the older version of the Camry is a transmission electronic control mode switch. When turned on, it operates in a sporty mode, increasing torque but also consuming more fuel. When turned off, it switches to an economical mode, which is more fuel-efficient. Pressing the ECT button during rapid acceleration or downhill driving can automatically complete the downshifting process. Below are the functions of the car's ECT and the correct usage of the ECT switch: Functions of the car's ECT: The car's ECT is mostly used on highways. When activated, the throttle response becomes more sensitive and direct, and the gear shifting typically occurs above 4500 RPM. When the ECT switch is turned off, the transmission switches to an economical mode, where the gear shifting logic is determined based on the actual road conditions and the driver's intentions. Correct usage of the car's ECT switch: When the ECT switch is pressed while the car is in motion, the car can automatically downshift. During downhill driving, the car's speed may become too fast, and frequent braking can lead to faults in the car's braking system, causing wear on the brake discs and pads. Pressing this button will automatically downshift the car, allowing it to drive at a lower speed. When activated, green English letters will light up on the dashboard, and the transmission will delay shifting, which helps maintain RPM. This mode can have an impact on the car's fuel consumption, potentially leading to increased fuel usage.

I've been driving my old Camry for almost ten years, and that ECT button has been my daily magic tool—touching it completely transforms the car. ECT stands for Electronically Controlled Transmission, which is essentially a driving mode switch function. Pressing the button shifts the transmission from normal mode to power mode, delaying the shift points to keep the engine at higher RPMs, delivering stronger acceleration—especially useful when climbing hills or overtaking. I remember once encountering heavy rain on the highway; pressing ECT improved wheel traction, allowing me to quickly escape a waterlogged area and avoid skidding risks. However, it does increase fuel consumption, so I only use it in emergencies—normal driving in eco mode is sufficient. The design of the old Camry is practical; this feature isn’t flashy but balances handling and safety perfectly, making it worth trying for every owner of an older car.
