the more i consider trading up the more i like the truck that i already have (2005 dodge 3500 cummins 4x4 dually w/48RE http://inlinediesel.com/trucks/3gen/1/index.html .....but i really want to
add an exhaust brake and need to know what my options are (with links were applicable) to include the controller. i really like the way you can simply turn it on in the '07 dodge rams and have it engage as soon as you release the accelerator pedal. is this the same on the aftermarket models or do you manually have to turn it on and off while braking? what options do i have here? jacobs says it cannot be done on an '05. thanks,

I don't know shit about them but read a article on a pac brake that seemed pretty good. Tom would be the go to guy here I think.
Or jump to the tdr.

same conclusion that i came to as far as keeping the truck. the 48re, until '06 at least, is not considered ebrake upgradable. you would need to do some tranny upgrades to add the ebrake. any tranny specialist could tell you what you need, i don't remember any more because i decided not to do it. as i remember, you needed at least an upgraded torque convertor but i think there were a couple more receommendations too.

Pacbrake says Jacobs is full of it :)

That will answer all your questions. Note they have a special "kit" for the '05s. The problem with the '05s is the ECM no longer has the exhaust brake function turned on (those DC bastards turned it off), so the kit uses a micro-switch on the pedal instead (so, when you lift off the pedal, and the brake is armed, it will engage). Note that they also use the ATS Commander transmission controller, which is EB-aware, and will keep the converter locked while the exhaust brake is on (until you hit a pre-set speed, then it will unlock).

thanks for the link.

is there a way to turn it back on? will the ECM from an '06 work?

anyway to avoid this? micro-switches are a common point of failure in my industry anyway.

any need for any tranny upgrades? thanks,

Nope - injector harness is different.

Yeah.... spend $40K on a new truck

As I've said before, I'd spend some money on tranny upgrades because of the weight you're pulling - not necessarily just because of an exhaust brake.

what about turning the feature back on? is there any way to interface with the existing ecm to turn the feature back on?

would you make this same recommendation if you werent running power adders, or is this recommendation based on running additional power over stock?

that really is a great question. i'll be interested to see what tom says. i would say for both. i know that tdr is full of people that added power without adding tranny upgrades and i would guess that way over half of them ended up with serious tranny problems that made them regret not upgrading the tranny. those who added power and upgraded their tranny's seem to be pretty happy, especially those that went to a "good" tranny source. but then the extra weight that you have, i would think, will make the cumins throw some real hard power to the tranny to get the weight started and i'm not sure the tranny would hold up real well under that either.

I don't know... you'd have to ask a friendly DC tech with a DRB3. Remember, Dodge changed the programming in the Cummins ECM so Cummins can't interface with it anymore... only Dodge can talk to the ECM anymore. I would think that if there were a way, companies like Pacbrake wouldn't be coming out with "fix-it" kits.

Either way. As I said, the stock torque converter is the last of the known "weak links"... it will be first thing to go from the heavy use of pulling that trailer. The new valve body gives you firmer shifts, a little more line pressure, and the ability to actuate shifts with the TC locked up (where lockup is maintained through the electronic controller - the same box that engages the exhaust brake)*.
* This is all assuming ATS parts and upgrades... can't speak to other transmission shop's products
