this is upgraded version of my car. shifting is according to turning speed of the wheels. you can see that while it is being slowed by using force, the gear is changed. (3 gears) Vites değişimini tekerlek devrine göre yapmaktadır. Görüldüğü gibi zorlandığında vitesi küçültüyor. (3 vitesli)

ZF 8HP 8-Speed Automatic Transmission
ZF has developed a new automatic transmission for cars with eight speeds that can achieve more than 6% fuel savings. The priority aim in development, however, was not the maximum number of gears, but minimum consumption. ZF engineers had set the bar high to produce a new benchmark for automatic car transmissions. The second generation of the ZF 6HP 6-speed transmission, that entered production only in 2006, defines standards that are hard to top: reaction times faster than human perception, direct engine linkage by early-stage torque converter lock-up and intelligent, adaptive control software, that almost reads the driver's intentions from his foot. But the new transmission is capable of even more - it saves (even more) fuel. It also guarantees ultimate driving enjoyment, as well as the variability needed to be able to use future technologies. http://www.zf.com/corporate/en/products/innovations/8hp_automatic_transmiss ions/8hp_automatic_transmission.html
