is it as reliable as conventional auto? depends on model but generally no.
Is it expensive to maintain? fluid services are similiar, got cheap got expensive. The expensive wear-and-tear service is clutch replacements, which typical cost thousands.
DCT's achilles heel is low speed high load conditions, eg. pro-longed slow traffic or going uphill slowly. Wet DCTs sort of mitigate this weakness but still not entirely.
They work better at high speed and hard acceleration, ideally coupled with powerful, high torque engines.
Lastly, driving a DCT requires a slightly different driving style to keep it healthy.
That would mean DCT not suitable for city driving where traffic jam and slow driving is common condition? Is it expensive to maintain? fluid services are similiar, got cheap got expensive. The expensive wear-and-tear service is clutch replacements, which typical cost thousands.
