BT the other brakes direct mount are all good starting in the order you used above cost Dollars more Dollars more Dollars for the same (allmost ) effect saving brakes and safe down hill with a load . Ron in Louisville Metro KY:-{} Take your pick.

FYI from this thread ( https://www.turbodieselregister.com/forums/showthread.php?s=&threadid=65285 ):

48RE Update

Due to some delays, testing of a 48RE transmission with the Cummins/Jacobs exhaust brake will not be completed before the end of March at the earliest. That's the best estimate of an announcement date I can give at this point.



As I understand it, the 48RE transmission was designed to be e-brake capable. However, endurance testing has to be completed before warranty certification is given.



If you add a brake now to your 48RE, you would be taking a chance that the e-brake is not approved for that transmission. If a brake causes a transmission failure, it would not be covered by warranty in this situation.



The 48RE transmission has higher internal pressures that allow it to transfer reverse torque. So, this reverse torque will occur even without a brake. However, because diesel engines do not have any throttle/butterfly or any other restriction, there is almost no deceleration caused by the engine and almost zero reverse loading on the transmission when coasting.

Steve,



Thanks for re-posting information from the other thread -- I hadn't found this one yet.



As most everyone knows, the 48RE transmission was designed with an exhaust brake in mind. However, reliability testing has not yet been completed so an exhaust brake is not yet approved as far as the DaimlerChrysler warranty is concerned. DC is performing the testing and is responsible for giving the OK. I'll make a post as soon as I hear something official.

My earlier question was how does the switch mount with the auto.

The Cummins/Jacobs/Mopar shifter-mounted brake switch includes inserts so that it can be mounted on either an automatic or manual shift lever. When the brake is approved for the automatic, the switch will be compatible.

Thanks Carlton,



I think I would prefer that it was on the dash vice the auto lever. But, if thats the way it needs to be, so be it.



Thanks again.

Thanks again.

Any two-position toggle switch can be used to connect the yellow wire and the green/yellow wire to enable the brake if no indicator LED is required.



To add an indicator LED, a Dual Throw switch (with two independent sets of contacts, DPDT-type) could be used. One set of contacts would actuate the brake switch. The other set would simultaneously operate a 12V LED or lamp, completing the circuit to turn-on the bulb.



Mandatory Disclaimer: This type of installation, of course, would be "on your own" and is not officially supported by Cummins.



We found that most owners want a shifter-mounted switch so we made that standard equipment for the MY03 brake.

I've never fully understood the warranty, exhaust brake with an automatic transmission, confusion. I understand that a diesel doesn't have a butterfly in the intake to bring about engine braking. I understand that a gas engine does. A 47RE behind a V-10 uses engine braking to help hold back the load on the downhills and the warranty is in full. The 47RE doesn't have a clue what's resisting rpm whether it be a diesel or gas engine. Why is engine braking ok with the V-10 and not with a diesel? So a diesel with an exhaust brake creates way more retarding HP than the V-10. Why not tune an exhaust brake with similar retarding HP to the V-10? Moderate engine braking is better than no engine braking.
