Second Gen 3.5 EcoBoost and 10 Speed Transmission

[FishOnOne]

Same horse power and torque is up to 450ft/lbs. Also a duel fuel system and a servo controlled waste gate.

This engine appears to raise the bar on pulling performance and fuel economy could raise the bar on gas engines.

The 10 speed appears to be equally an impressive piece that is a very compact package.

With a 516 lb-ft torque rating you'd think it would be beefy enough for anything you'd actually want to try to tow with either of the Hemis, but I guess they could get a slightly higher tow rating for marketing purposes with the other transmission.

I agree. What are they waiting for?

Probably strength and durability.

Even with fixed input (engine) power, the more mass is behind a transmission, the sturdier it has to be. This is also the reason Ram still doesn't have the 8 speed ZF behind the 6.4 Hemi on HD trucks. Also an excellent transmission btw.

Agreed. The 8-speed in our Durango is always in the right gear and is smooth as butter and doesn't exhibit shift busyness. It just does it's thing.
I do imagine at some point RAM beefing up their 8-speeds for heavy duty applications or turning to Aisin when the time comes.

Ram doesn't produce the 8 speed transmission. It's been outsourced to ZF.

Transmission of course.

"Beef up" can imply hundreds of millions of $ of R&D and re-tooling. You don't think Ram would've beefed up the 8 speed by now for their HDs? Or use stronger ones out there, like the variant on the Rolls Phantom?

Good point. Easier said than done.

Does Ford have a "bad" auto trans in late model pickups?

Honestly, give me the Ecoboost with the current 6 speed than, worthy upgrade over the 6.2 imo, at least in the SRW trucks.

Ford thought so too in the Raptor.

Transmission manufacturers have years and years of experience with high numbers of gears with excellent reliability. Europe (once again) has been ahead of us in this game for sometime.

For trucks they have as many as 18 gears or "speeds" with the most common now around ten. Both in Automatic, semi automatic and manual type gearboxes.

Reliability would not be my first concern.

To be fair though, an 18 speed auto / semi-auto, such as Eaton Auto-shift, Ultra-shift, and their equivalents in Euro Class 8 trucks, have NOTHING in common with a torque converter, planetary gear automatic. The former is simply a manual transmission with computer assist shifting and clutching.

Not saying the 10 speed auto won't be reliable, just that it is the very first. Euro / Asia does not have such a transmission before us.

Honestly, after 3 years of Ecoboost experience, I agree. I would rather have the EB than the 6.2 or any of the other gas offerings, to be sure. I think it would be a great drivetrain to tow 8-10k lbs, in a truck with plenty of payload and capability.

I know that my 3.5 made easy work towing my 6500 lb TT. The truck chassis, however, was about at its limits.
