And remain most popular globally.

Torque converter have been around a long time and have been a result very quiet reliable.
Multiple clutch are used to transmit the power of engine to gear box.

Torque converter are made by 3 main components

With help of these component achieve different different speed ratio.
How ever some time this conventional AT some time shake away little bit in drive ratio and have less fuel economic than regular manual transmission.


• most Refined, smooth,
Reliable            ;         
• more responsive than a CVT.


• lower fuel efficient;
• little bit expensive.

Cars offered with Torque Converter: Hyundai Creta AT, Maruti Suzuki Ciaz AT, etc.


AMT is the one of the simplest application of AT and most popular in ATs since 1970s. With advance technology.
The AMT have comeback in the r emerging markets ogear box.

A AMT is a regular manual transmission system in addition of electro hydraulic actuator system.

This type of automatic transmission provide really quick shift and also provide good fuel economic.

This technology is fairly complex because it uses various electronic components
So cost of this this CVT gearbox is high.


Pros: Lightning fast and smooth gear shifts, fuel efficient.
