I just heard that there is a car with dual transmission. Is this true? Does anyone know about them or own one? What kind of car is this?
I know the Semi-trucks have this but I didn't know cars did.

Hey. I've never heard of dual transmission but I've heard of double clutch transmission. I'm about to purchase a revolutionary transmission system in a vehicle made by VW; a 2007 Golf GTI. The system is called DSG or direct shift gearbox. The technology was produced by BorgWarner and licensed to the VW family of vehicles (VW, Skoda, SEAT, Audi, Bentley, Bugatti) and works by using two clutches to induce fast gear shifts while actually eliminating the torque converter used in regular manual transmissions. There are six gears total: 1, 3. and 5 on one side with 2, 4, and 6 on the other. By using a clutch pack made up of four smaller stacked clutch plates, the gear is automatically preselected and gear shifts go up in a 8ms. However, it takes 600 to 900ms to downshift. DSGs can upshift faster than SMT (sequential manual transmission). SMT is used in BMWs and the Ferrari Enzo which actually take 150 ms to upshift. Yes, my GTI will upshift faster than the Enzo!! (I'd rather have the Enzo though^@^) The gears are surrounded by fluid so that upshifts are faster and smoother and in turn can actually save drivers up to 10% in terms of gas consumption over regular automatic transmissions. Compared to all over types of transmissions (manual by far is the slowest, then CVT, DCT, SMT, etc.), DSG is set to take the automotive market by storm. Unfortunately, it will be a while before domestic car makers will be able to provide such technology in their vehicles; GETRAG (Ford) comes closest but is only offered in high end sports cars. Good luck racer girl.^@^

Some of the early '80s Dodge Colts (and Mitsubishi Mirages) used such a thing. The one on the right had two positions labeled "Power" and "Economy" (basically a low and a high gear) while the one on the left was a four speed shifter. Each one operated a different set of gears, and each combination of the two would yield a different gear ratio so it effectively had eight forward and two reverse gears.
Many SUV's use a similar setup - they have one normal transmission, and then a transfer case with three settings: 4-Low, 4-High, and 2 wheel drive (which is also high gear).
