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.

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
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
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
