Understanding Sealed Transmissions
Sealed transmissions are becoming increasingly popular in the automotive industry. Unlike their traditional counterparts, sealed transmissions don’t require a dipstick for measuring fluid levels, and the fluid inside doesn’t need to be changed as often. But, what are the different types of sealed transmissions, and why are they necessary?
Let’s dive into it.
Types Of Sealed Transmissions
- Continuously variable transmissions (cvt): Cvt replaces gears with pulleys and belts that create an infinite number of ratios, giving your car a smooth acceleration.
- Dual-clutch transmissions (dct): Unlike a traditional automatic transmission, dct has two clutches that alternate gears, giving you quicker and smoother shifting.
- Direct-shift gearbox (dsg): Similar to the dct, it allows for faster and smoother shifting due to its two gear sets that work alternatively.
Additionally, some automakers have their unique versions of sealed transmission.
