ZF announced its 8-speed automatic transmission (8HP) will be available in the 5.7-liter HEMI V-8 and standard with the Pentastar 3.6-liter V-6 for the 2013 Ram 1500 pick-up truck.
The 8-speed automatic transmission is designed to work in conjunction with the Ram 1500’s stop-start technology. This function is enabled by the development of the hydraulic impulse oil storage (HIS). It supplies the hydraulic oil that the transmission’s shift elements need for starting. When the engine is switched off, it allows for a quick engagement– as it is required with the stop-start function.
The new Ram 1500 will be available with a 3.6-liter Pentastar V-6 that Chrysler says will deliver 13 percent more torque and 20 percent better fuel-economy than its current 3.7-liter V-6 offering or a 5.7-liter V-8 Hemi that promises a 10 percent mileage improvement.
Models equipped with the new eight-speed automatic dispense with column or console shifters, replacing them instead with a new rotary knob mounted on the center stack to the right of the steering wheel. Trucks with the six-speed automatic still get column shifters.
Other functional upgrades include a Jeep Grand Cherokee-derived airbag suspension with multiple settings for on-and-off road situations. As with the SUV it’ll also offer an “Aero” mode to lower the ride height for increased efficiency.
