Transmissions
The A580 automatic transmission benefits Jeep Wrangler as much as the new petrol engine, with more refined shifting and gear selection. By increasing the number of speeds, the transmission allows the engine to operate in a more efficient RPM range, which helps increase fuel economy. More speeds also enable the engine to remain in the torque curve, increasing acceleration. The new Wrangler (two-door) boasts a 37-percent improvement in 0 - 100 km/h time, which is now 8.1 seconds. Also, a lower first-gear ratio in the new automatic transmission gives the Wrangler more off-road capability via a lower overall crawl ratio.
Electronic Range Select is standard for all automatic-equipped Jeep Wrangler models. The electronic stability control (ESC) also has been optimized to perform effortlessly with the new 3.6-liter V-6 engine.
Along with the proven NSG 370 six-speed manual transmission, engineered for the newest Jeep Wrangler are a new clutch housing, flywheel and long-travel damper clutch. The improvements are a result of the adaptation of the transmission to the 3.6-liter V-6 engine.
The five-speed automatic transmission is produced in Kokomo, Indiana (ITP2), and the six-speed manual transmission is produced in Gaggenau, Germany.
