What is ECT ECU?
The ECT ECU has lock-up clutch operation pattern for each driving mode (Normal and Power) programmed in its memory. The ECU turns the No. 3 solenoid valve on or off according to vehicle speed and throttle opening signals. The ECU controls lock-up timing in order to reduce shift shock.
Does 4 speed mean automatic?
A 4-speed gear means the car can move between four different ranges of speed and RPM. A car with a 4 speed automatic transmission will accelerate slower than a 6-speed transmission because it has to cover more speed (mph or kph) before shifting to the next gear.
What is Super ECT transmission?
Toyota Motor Corporation has developed a new four-speed automatic transaxle U140E named “Super ECT”. The U140E has achieved compactness which enables it to mount on many new platforms, achieved high efficiency, which contributes to improve fuel economy, and it achieved good shift feeling, response, and reduce noise.
Is CVT automatic?
The CVT is the newest type of transmission. It is sometimes referred to as the shiftless transmission and is a type of automatic.
Is a 10 speed transmission better than 6 speed?
Compared with the 6-speed, the 10-speed delivers improved overall performance, with enhanced acceleration at the low and mid ranges of the power band. Features include optimized wide-span gear spacing coupled with drag-reduction actions plus three overdrive gears.
Are 6 gears better than 5?
In recent 6-speeds, the extra speed from a 5-speed allows the engine to run at a lower RPM and save fuel, comparatively. This difference is most effective at highway driving speeds.
What is a Type 4 SPD component assembly?
Type 4 Component Assembly SPD (Component Recognized) –– These component assemblies consist of one or more Type 5 SPD components together with a disconnector (integral or external) or a means of complying with the limited current tests in UL 1449, Section 39.4.
What is the rating of a type 1 SPD?
Type 1 SPDs include watt-hour meter socket enclosure type SPDs. Being on the line side of the service disconnect where there are no overcurrent protective devices to protect an SPD, Type 1 SPDs must be listed without the use of an external overcurrent protective device. The Nominal Discharge Current Rating for Type 1 SPDs is either 10kA or 20kA.
How does the electronic control transmission ( ECT ) work?
The engine ECU monitors coolant temperature and sends a signal to terminal OD1 of the ECT ECU. The ECU prevents the transmission from upshifting into overdrive and lock-up until the coolant has reached a predetermined temperature. This temperature will vary from 122’F to 162’F depending on the transmission and vehicle model.
Can a SPD be listed without an overcurrent protective device?
Being on the line side of the service disconnect where there are no overcurrent protective devices to protect an SPD, Type 1 SPDs must be listed without the use of an external overcurrent protective device. The Nominal Discharge Current Rating for Type 1 SPDs is either 10kA or 20kA.
