2. INTRODUCTION
• Power Transmission from Engine to wheels.
• Dual clutch Transmission
Semi automatic or automated manual transmission system
which uses two separate clutches for odd and even gears in
synchromesh.
• The gears are controlled Hydraulically by a Electronic control
module which senses the gear position and shifting in semi-automated
manner.

3. SINGLE CLUTCH TRANSMISSION
• In this kind of transmission there is only one clutch system and when the
operator has to change a gear he needs to press the clutch pedal to operate
the gear lever.

4. DUAL CLUTCH TRANSMISSION
• Dual clutch transmission, it is two separate manual gearboxes contained
within one housing, and working as one unit
• Sophisticated electronics and hydraulics control the clutches. One clutch
controls the odd gears while the other controls the even gears

5. DCT ARRANGEMENT
• DCT has one lay shaft like a normal gearbox, but two output shafts. One
output shaft has 1st, 3rd and 5th gears on it while the other has 2nd, 4th and
6th.
• The lay shaft is actually two shafts one inside the other connected to two
concentric clutches at the end.

11. ADVANTAGES
• Better fuel economy up to 15% improvement than conventional
transmission.
• No loss of torque transmission from the engine to the driving wheels
during gear shifts
• Extremely fast up-shift time of 8 milliseconds
• Very smooth gear-shift operations.

12. DISADVANTAGES
• Relatively expensive to manufacture and therefore increases
new vehicle purchase price
• Heavier than a conventional manual transmission
• Expensive transmission fluids/lubricants with dedicated additives
are required, which need changing on a regular basis

13. CONCLUSION
• New environmental and fuel efficiency legislation have triggered new
automated transmission technologies. The most likely winner that will
replace traditional system will be the dual clutch transmission (DCT) as it
offers the best of fuel efficiency as well as comfort and performance.
