what is the purpose of sportronic transmission?
Not really sure to give you the idea of what shifting is, but you need a clutch to get the full effect an your still limited unlike a actual manual transmission. I used mine on steep hills, that's about it.
The sportronic transmission was made to simulate the feel of a manual transmission without the use of the clutch pedal. It gives you the control of gear changes when passing in the highway or climbing uphill. At the same time it saves your left leg from fatigue when driving through heavy stop and go traffic. It's a user friendly manual transmission.
