What is Transmission?
The transmission system is one of a vehicle's most basic and important parts. You can define it like this, it transfers power from the engine to the wheels. Transmission simply refers to the gearbox, which uses gears and gear trains to provide speed and torque.

Intelligent Manual Transmission (iMT):
Simply and quite accurately put, the iMT is a clutchless manual transmission. It is similar to a manual gearbox, with gears and a gear lever. The driver almost feels like an automatic car as the iMT doesn’t have a clutch pedal but a brake and an accelerator pedal.

The iMT transmission system cannot automatically shift gears. On the other hand, with an IMT car compared to a manual transmission car, fuel efficiency and mileage are subjective and dependent on the driver's driving style.

Dual-clutch Transmission (DVT):
This transmission employs two separate clutches for odd and even gear sets, allowing for especially quick shifts. The design is often similar to two manual transmissions in that their respective clutches are within a housing and operate as a single unit.

The DCT operates like an automatic transmission, requiring no driver input to change gears. This transmission type can generally be automatically operated or moved manually with the pedals on the steering wheel.

Intelligent Variable Transmission (IVT):
These are pulley-based transmissions primarily used in small vehicles with smaller engines, and they can change gears seamlessly through a constant gear ratio. This is in opposition to other transmissions that offer a limited number of gear ratios in fixed stages.

The IVT uses two pulleys between which a steel belt runs. To continuously change its gear ratio, the IVT simultaneously adjusts the diameter of the “drive pulley,” which transmits torque from the engine, and the “drive pulley,” which transfers torque to the wheels.
