800 punds of torque coming soon!

[mwilson]

Why is the manual transmission always the "Red headed step child" in these power upgrades? The answer to the increased torque and allowing the manual transmission guys partake in this improvement is stairing Dodge in the face ... it is called an Eaton/Fuller FSO-8406A!!!!

Source out the transmission to Eaton and Dodge can have a nice new shiny badge on their trucks next to the Cummins badge that says "Road Ranger".

And no, I'm not full of you-know-what when I make this statement, I am serious! (Maybe a little full of it if I said they should use an 8LL). But come one Dodge! If you can't get a manual that will handle the increased engine numbers from your current manual transmission supplier ... go with Eaton ... what a win-win that would be.

I second that!!!!



Plus you would have a REAL clutch to work with.

You could easily add transmission coolers, internal oil pump, transmission would already have two PTO openings, no funky lube oil, simply synthetic 50 weight, the list is endless... .....

Parts and pieces such as flywheel, flywheel housing for example already exist, no brainer.

But how does the size, weight, and cost of an Eaton/Fuller Road Ranger compare to the German designed, Brazil sourced, G-56 forced on Ram by Daimler?

Isn't it far heavier and considerably larger? It would probably add $5,000 or more to the cost of a manual tranmission Ram. I can hear the whining from here.

 

[mwilson]

The Fuller FS series really aren't all that big, nothing like their huge twin countershaft brothers.

If I can during lunch today I will try to find some figures for weight in my Fuller literature, it is an interesting question.

Is the Fuller synchronized? Remember the market Dodge is selling these trucks into - most of the buyers don't know how to "float" shifts in a non-synchro gearbox.



Rusty

 

[mwilson]

Yes, the FS series are all syncro as far as I know.



The target market for that series of transmission is 26,000 lb GVW and below with juice brakes, No CDL required, gotta' make them shift easy so you can throw anybody in the truck to drive it.

Go here:

5- & 6-Speed



and click on the Sales Liturature on the right side of the page.



Yes, the transmission is synchronized. and it weighs 359 lbs. no problem for the truck.

 

[RVTRKN]

I looked at the specs, and it just might be convertable, but are there any adapters to the CTD and transfer case.

 

[mwilson]

Now, what does the current 6-speed weigh???



Seems like they could design a transfer case adaptor, the rest is already there for them.



A big truck would use a divorced mount with a short driveshaft in between.



Mike.

 

[RVTRKN]

A doable #359lbs

 

[RustyJC]

That's lighter than the NV5600 was, right?

Good, so someone with the ear of the Dodge CEO call him and tell him to contact Eaton and source the trannies from them.



That would really be a major WOW factor as he like to use the term.

Oo. Oo.



I still think a 7 speed would be a great trans. Something with the 1-5 ratios of the NV5600 or FSO-8406A but with a . 85 and . 65 OD, more of a towing and an empty OD. Would be a pretty unstopable manual trans.

That would take a long distance call to Italy. :-laf

 

[HBarlow]

But who would want to buy or drive a Ram with that tranmission?. 1st gear ratio is approximately 7:1 and there is no overdrive. 6th gear is direct.

No thanks. It's probably more durable but it wouldn't sell in a Ram.

 

[RustyJC]

Hmmmm... . with a direct 6th gear it would need a 2. 27:1 rear axle ratio to match someone's "wish list" for 3. 73s with a 0. 61 overdrive 6th gear. :-laf Then the 7:1 first gear might make more sense.

[mwilson]

Harvey,

Go back to the spec chart and to the bottom, you need to look at only the 6 speed FSO models (O = Overdrive)



FSO6406A

660ft/lb rated torque

1st gear 7. 05

6th gear 0. 78



FSO8406A

860ft/lb rated torque

1st gear 7. 05

6th gear 0. 78

[RLHannink]

I wouldn't mind a really tall rear end, and a direct drive top gear in the trans. Then for the majority of the miles the power would be going straight through. And the taller axle gears are inherently stronger, larger pinion gear. Makes too much sense though, it'll never get engineered into our size trucks.

 

[rscurtis]

Since Ram has the stick shift market all to themselves already, this might make sense for the 800 ft. /lb. crowd. Even if the option was $1-2K, the Ram would still be thousands cheaper than the Ford, with an option they don't offer to begin with. It would also use a real clutch.

You were looking at a FS series, not a FSO series. The O indicates overdrive. Its a . 78:1 as others have noted, with 3. 73's it makes a killer OD for towing.



Here are some of the ratios of Dodge trans vs the FSO.

I think it is the same.
