Chrysler initially received the 8HP 8-speed automatic transmissions from the ZF plant in Germany. By 2013, in parallel with Chrysler Group, ZF had set up a new transmission production plant in Grey Court South Carolina. ZF Friedrichshafen and Chrysler Group have reached a supply and license agreement for the 8HP. Chrysler Group is licensed to produce the 8HP at the company’s Kokomo transmission plant and the Kokomo casting plant, production began in 2013. This transmission is marketed by Chrysler under their own brand name, the TorqueFlite 8.
2nd generation 8HP products were released starting in 2014. Efficiency improvements over the original design include a wider ratio spread of 7.8:1, reduced drag torque from the shift elements, reduction in required oil pump pressure, and broadened use of the coasting and start-stop systems. ZF estimated fuel economy improvement over 1st generation 8HP kits to be 3%. Refinements were also made with respect to vibration.
3rd-generation 8HP products were released starting in 2018. Major improvements are total spread of 8.6 and fuel economy improvement of 2.5% compared to the 2nd generation. The gear ratio spread on this unit allows for a very healthy torque curve at all times.
This 8HP70 torque converter is available in a variety of stall speeds.
