[QUOTE="UnleashedBeast, post: 13700406, member: 112023"] After all these upgrades power is still rated at 420. Torque only gets a 6 ft. lb. increase over the previous generation. Perhaps the tune is leaving more on the table this time. In the next 6 months, this question will be answered. Roll back to 4.6L 3V technology, requiring more "delete" parts when upping the power of the engine. Don't know how I feel about this. Weight loss from the case is a good thing, however.....designing it to run hotter? I'm assuming they made the case smaller (weight loss), holding less fluid, and tweaking the external cooler thermostat to open slower. Ford, all you had to do was use a better ATF that didn't thicken as much as it cooled. I know what they were aiming for. The current 6R80 doesn't achieve full temperature on short trip driving. My 15 minute 8 mile drive will only raise ATF temps to the ~135*F range. That's why a better ATF which maintains a lower viscosity while cold and better anti-wear additive package was a great idea. Some people install the deeper pan on the current 6R80, which isn't required. The OEM cooler has no problem keeping temps down on the street and drag racing. [/QUOTE]
