Considering a New Truck
With dodges new 8 speed Auto, is the shift dail electronic, or activated with rods and leavers?
I don't like the push start on the Ram, lot of dodge aspects I hate that relate to qualify control, but dodge is in the running due to my appreciation for the hemi.
2014 seria 1500 with 6.2v8 crew cab or a hemisphere crew cab 1500

Here is the short version of the 8 speed.
The 8HP70 is an electronic eight-speed automatic transmission. The
Transmission Control Module Assembly (TCMA), which is integrated into the valve
body, provides fully synchronized clutch-to-clutch shifting through four
planetary gear sets. The TCMA includes a mounting plate that holds the
Transmission Control Module (TCM) and a molded wiring harness for connection to
various transmission sensors and solenoids. The valve body assembly contains
all the sensors and solenoids required for operation, completely inside the
transmission. Eight speeds allow the engine to maintain its optimal rpm range,
increasing fuel economy and performance.
Transmission control is performed by the TCM based on hard-wired and CAN bus
signals from sensors and modules. The TCM receives driveability data from the
Powertrain Control Module (PCM) and other modules over the CAN-C bus. It also
receives shift lever position information from the electronic shifter over a
dedicated transmission CAN bus. The TCM processes this input data and controls
operation of the torque converter clutch, park lock system, solenoid valves,
and pressure regulating valve.

As TN said, the push button start really isn't that big of a jump. The "keys" for all 4th Gens are really only an electronic fob, the exact same one still used by Mercedes, a holdover from the Daimler days. The current key just sticks in the dash, but it's no real difference from a push start.

Thanks for answering my questions, I test drive a GMC with the 5.3, and it is all new, lots of power, nice ride ( I always liked GM trucks ride) but I hate the seats (SLE)
Ironically, Courtesy Chrysler is offering substantially less for my 2500 ram on trade on a 1500, 2013 Ram slt crew cab.
Any one know if the diesel Ram in the 1500 will need urea and will have EGR on the exhaust and ex issues that are in the 6.7 ctd trucks?

from everything I've seen it's the same junk. The canadian dodge website is absolutely useless and has no tech info but third party sites seem to have pic and notes about a urea fill cap next to the fuel cap.

Putting the “Eco” in EcoDiesel
The new EcoDiesel V-6 achieves 50-state emissions compliance for both tier II and BIN 5. A key enabler is the engine’s cooled Exhaust Gas Recirculation (EGR) system, which is controlled by electric valves instead of the conventional pneumatic variety. The system also contributes to rapid start-up.
A state-of-the-art Selective Catalytic Reduction (SCR) system also reduces emissions. It incorporates a unique Diesel Exhaust Fluid (DEF) system that, unlike competitive systems, alerts the driver to low DEF levels while also allowing the engine to maintain full power. Other features include:
The standard engine oil cooler, when the EcoDiesel is used with 5W30 synthetic oil, contributes to a 10,000-mile oil-change interval. The use of B-20 biodiesel is validated and approved for the new 3.0-liter EcoDiesel.

- An insulated DEF tank with heated lines mitigates the effects of cold-weather operation
- A passive cooling system (one that does not require engine coolant) for the DEF injector
- Exhaust-system refinements to improve the utilization of DEF for NOx reduction while also mitigating harmful DEF crystalline build-up
- An exhaust-system design that requires less energy from the engine to achieve optimal emissions conversion temperatures
- An exhaust-system strategy that reduces soot output while also improving fuel economy and meeting emissions standards
