Should I get an exhaust brake?
Just bought and finished installing the pac brake myself. Fairly simple to do. Also a very good quality product.
Also bought the airbag helper springs from pacbrake as well. I'm a little slow on getting those installed as I am dithering over getting the in cab control switches for them.

Got a BD EB use it a lot pulling 12K+ 5er--LIKE it even MORE with the mystery swith
on my 04(w/a momentary toggle switch).
Coulda saved $ not buying the transloc and done the mystery switch instead!

Autojohn, what happens with my setup is that I have a device called the autoloc which will keep the tcc clutch locked up if the cummins/dodge electronics request it to be on and the switch is on for the exhaust brake.
I guess the idea is that there could be some damage to the tranny if conditions weren't right to have the tcc in. That's why they wait for the cummins/dodge stuff to initiate it. The problem is, I want braking when I want braking!
The good part about the autoloc is that it will disable the tcc if you get below a certain speed to avoid lugging the engine and shuddering the tranny. This works pretty good and I want to maintain the auto function on this end of things.
So, I was going to have a timer which would pulse the tcc clutch for 1 second (and get the autoloc on to keep it locked in) when:
1) The bd brake switch is on
2) The throttle was returned to idle
This logic is already in the box that everyone gets with the brake, so I just have to add a pulse timer to get it to work.

Looking to get some advice on whether I should be investing in an exhaust brake. This is my first diesel truck and we just purchased a new fiver last year and it has a GVWR of 8844 and pin wieght of 977. I know this is not much compared to what some of you guys pull but I have not had any experience pulling in the mountains and we are planning a trip to the west coast this year with more trips like this planned in the coming years as well.
If you don't think I need an exhaust break perhaps you could give me some pointers on mountain driving.
thanks in advance

No one mentioned it so far, on a 06-07 5.9 all the control of the EB is done by the Dodge ecm so an 05 or older uses a control module from pac to achieve breaking and sucks. All the Pac brake or others is looking for the signal from the ECM. Also the ECM senses when you turn on.
The ECM now is sensing an EB is active. Thus at this point it changes programming sorta just like when you engage the TH mode. It bases the control of the EB by several perimeters, throttle position's, rpms, TQ lock up, and engine temp.
I've had many talks with Pac about this do to New trans and how differant things now are.
So yes on an EB set up you won't be sorry.

Thanks again guys. Looks like I"ll be getting one and also thinking about a smarty jr.
One more question. I have a remote starter on my truck and I am wondering if there could be any problems with the addition of a Pac and smarty. What I am wondering is if this would be a concern for the ECM?

[QUOTE=andes2;2934866]Thanks for the info guys please keep it coming.
I was wondering if there are any issues with using the Pac brake in the winter?
If you engage the brake while on slick roads you can get sideways especially in 2wd, the rear end will step out. I live in Denver and have pulled a 27' enclosed snowmobile trailer w 4 sleds and in 4wd the EB works great. You just shouldn't engage it at high rpm's on slick roads. BTW I have a 6 speed manual and love the EB. Went down the west side of the tunnels w 10k in tow in 5th gear and the EB held me at 55 mph all the way down, about 7-8 miles at 6% I think.

My '08 has one and let me tell you .... I don't know why it didn't come standard a long time ago.
It makes braking while towing a dream but like others have said it's not good to use it heavily in bad weather.

Also have PB air bags, but you should look into the AirLift wireless controller, way nicer than running more wiring and air lines into the cab to a big ugly gauge and switches. (Link in my signature.)
There is only one word needed to answer your question... "YES!!!"
I will never own a diesel without one again, its amazing what they do.
Dodge actually "requires" them for trailers over 10K lbs, which is odd considering auto's were rated for over 10K before 06, and 06 is the first year an EB is OEM approved for an auto.
