( http://www.TFLcar.com ) The 2014 Chrysler 300C is a luxury car in the classic American tradition of Luxury. It is big, bold and imposing. It is also technologically advanced with a new 8-speed automatic transmission paired to our testers ubiquitous Pentastar V6 Engine. In another accurate fun and informative TFLcar review Nathan and Roman take the big Chrysler up the Ike Gauntlet to see how the new eight speed transmission handles the steep grade. From Dillion, Colorado to the Eisenhower Tunnel US I-70 climbs 8 miles to a maximum elevation of 11,158 feet or 3,401 meters. That's enough elevation and grade to test the 8-speed transmission of the 2014 Chrysler 300C.
