48RE + Exhaust Brake: Current Status

[p-Bar]

If I had the 05 I would just put one of those trans commanders on and an aftermarket jake. Yours should have the thrust washers , my year they won't give me a change date when they started installing the washer.

48RE Jake Brake

Just wondering why this was posted again, is there something in the works for us 2005 owners? As one of three 2005 owners I have met waiting for the software upgrade because a dodge dealer installed the brake on my truck and then told me it would not work without software update from DC which was forth coming. So we have the brake but cannot use it without software upgrade.

If there is any new info on this please share it with all the 2005 48RE owners that are waiting.

Question for Carlton Bale

I was very happy to discover this thread today. Thank you Carlton for your iinfo. I have a 2000 with the 47re and the extended warranty expires in March.



I know the 47re is not approved. BUT... . I would like an E-brake. I tow a 4-5000 lb boat trailer combination and then add camping gear. I will be adding a cab over camper also. something light, like a Lance 815.



Since I will be my own warranty station soon, what might I expect if I install a Jake or a Banks with a trans loc module. Trans is stock except I added a double deep pan & a temp gauge. I don't want it to granade though.

I've never seen any temp over 175 even towing in 115 degrees here in PHX.

150 degrees is normal.

Is there a possibility of obtaining a new ECM, and assuming we would have to buy it, that is compatible with the 04. 5 48RE so an exhaust brake can be accommodated?

I am in the same boat. However, I am not holding my breath as DC obviously has better things to do than give a darn about customers who have already bought their product. They'd rather we "just go buy the new model". As usual, we'll probably have to resort to an aftermarket solution. This is annoying, but this transmission needs some help anyway. That said, I will welcome an update if it arrives before my warranty is over and I have DTT do it right.

 

[p-Bar]

We still have the issue of the thrust washer since nobody will give us a build date of the change over of the thrust washer.

 

[AWise]

'06 models do not have the issue with the thrust washer, correct?

That is correct

Bringing a dead horse back to life.

Did anyone ever get a part number for the bad thrust washer?
My truck has about 102k miles and at 464 RWHP is not feel that tight anymore.
I am getting ready to rebuild the transmission and want to be sure I install the updated thrust washer.

The only info I found after reading the entire thread is,
"I'm not an expert on this but I believe it is the #5 thrustwasher, which is on the back side of an outer ring gear in a planetary gear set. It is only significantly loaded when the engine is producing high braking torque (which is only with an exhaust brake enabled). The washer was changed by adding a lead coating, which other washers within the transmission already used. "

forget the help from DC

Now that DC is dumping Chrysler, I wouldn't even hope to see anything to fix that problem from them. That pretty much puts all of us on our own now.

I just installed a BD exhaust brake in my 04.5 dodge . Carlton made such a big deal about the converter being locked upped and it really doesn't seem to be one after all . Very confused about Jacob's mindset on that issue...

 

[cerberusiam]

Without the TC locked you don't get full braking effect, about as effective as putting an EB on a 518. Was a good conversation topic for a while but in the end that is all it was.

 

[Ozymandias]

If he installed the real Jacobs Brake from Mopar/Cummins then his converter will lockup, also he has a downshift from 4>3 around 60MpH when he pulls the Knob, Converter stays locked down to around 30MpH.
Also the warm up feature is there.

The only thing the Driver has to watch for is that the converter is truly locked up after the 4>3 downshift because the EB kicks in faster then the converter can lockup again, at this point you need to feather the Accel Pedal to give the time for a finished lockup. Otherwise it slips and this couldn't be good for the clutches.
Best way to determine if the converter is truly locked is to watch the rpms, if they drop to around 800-900 after the EB is activated then it isn't locked up.

 

[Ozymandias]

Sorry I see now that he has a BD, don't know how deep integrated to the ECM this EB is.

 

[p-Bar]

Cerb yes understand the the whole lockup thing just funny how Jacobs made such a big deal about the lock up . Ozy I have a stand alone lock up unit from BD pretty smart does a good job at locking up.

 

[cerberusiam]

The big deal was mostly Dodge and looking for ways to minimize exposure if something failed. Even with a BD you can still tap that wire the Jacobs does to get the same functionality. It is an EB sense function already built into the ECU and if the TCM is smart enough it will recognize it and behave accordingly.

As Ozy says, sometimes it does not work perfectly in tune with the TCM. That was the big problem that Dodge was worried about, it wasn't idiot proof. As long as the TV pressure will stay at or above 110 psi or so with the EB activated it should work fine, ther eis not enough braking to slip a good TC at those pressure. The problem is with a stock trans is if that TV pressure falls off to 50-60 psi that is normal with the throttle closed you may slip the TC clutch and that would cause warranty issues.

If it works and will maintain pressures by tapping into the internal EB sense wire you are good. If not you might have to look at the BD TQLoc that manually holds the TV cable maxxed when the EB activates. Therer are ways around the lack of integration that Dodge would not consider but seem to work fine for the rest of the world.

 

[p-Bar]

Understand Cerb. Both BD and Pacbrake require the use of their lock up module , Jacobs can use the firmware in the ECU. I chose the Torqloc which lets me have a little more control of the torque converter and since I have rebuilt and used Goerend parts valve body and torque converter the pressures will stay up there as needed. Guess we will put this thread to bed now

 

[MCrossley]

I have had my Jacobs brake on my 05 since new and just use my head on when it is locked up to engage. That being said did anyone every get an 05 ECM to actually control the brake? I thought that never was going to happen but reading I am wondering if someone actually did tie into the ECM with some sort of success would be nice to not have to remember to turn it off and on when hitting the throttle... If not were any of the controllers found to be really good?

 

[p-Bar]

I put the torqloc from BD on it works perfectly. Give them a call.
