However, there exists a second and third category of automobile technologies, namely, continuously variable transmission or CVT full form (Continuously Variable Transmission) and direct shift gear or DSG full form (Direct-Shift Gearbox). Every AMT full form (Automated Manual Transmission) works on a set of decided mechanisms. CVT, or continuous variable transmission, is an automatic transmission which modifies engine power output. It replaces fixed gears using a pulley system and belts. The capacitive voltage transformer step-down the extra high voltage signals and provide the low voltage signals which can easily measure through the measuring instrument. The Capacitive voltage transformer (CVT) is also called capacitive potential transformer Re: Automatic Transmission (AT) – TC / CVT / DCT / AMT: All You May Want To Know of A I agree with most points except a couple 1) CVT sold today are CVT with Torque Convertor, so in City stop and go traffic conditions, even this combo will suffer from poor fuel efficiency for same reasons as TC with conventional gearbox. 2) DCT is even more fuel efficient than AMT but the biggest drawback is our stop and go conditions is the replacement of the clutches, while in AMT it is a simple job to ...
