If you're like most drivers, your car rides smoother when it's in gear. And if your car has a manual transmission, you know that shifting gears is a delicate and time-consuming process. Fortunately, modern transmissions are designed to last longer than ever.
But just like any other mechanical device, they can eventually need manual transmission rebuild. This article will outline the different types of transmission repairs and what you should do if your car needs them.
The first and most obvious difference between manuals and automatics is the shifting efficiency. Manual transmissions have a clutch that engages gears, while automatics (like those found on modern vehicles) shift through a series of mechanical relays. The lack of a grip means that manual gearshifts take longer than automatic ones.
However, the higher torque capacity of automatics allows them to get out of gear quickly when they need to, which helps prevent premature wear on your transmission. To further this point, in manual-transmission cars, you often hear the car clunking into gear as it's shifted at higher speeds. Auto transmissions tend to just get quiet.
Gear Ratios And Mileage/Fuel Efficiency
CVTs are especially good at shedding excess RPMs, which is why they're more efficient than automatic transmissions. When you drive an automatic, you're constantly spinning the engine at various speeds to shift gears.CVTs can spin the engine at low speeds without moving the vehicle's wheels, which means it can rev higher and thus burn less fuel.
The same effect results from a lower gear ratio in a CVT system. The lower-ratio CVTs also tend to be more efficient than traditional automatics; in fact, some automakers have claimed that their CVT-equipped cars will go as far as 75 mpg on the highway (CVTs can't be programmed to just coast down hills).
