Does one exist? Every one I have seen is for the newer trucks or for one with a manual transmission. Definitely one mod I would invest in if I could get my hands on it.....

I'd recomend the Pacbrake PRXB. The kit comes with the trans controller for your auto.

They have one for early and late 2004's.

Both BD and Pacbrake make a ebrake for your truck, you just need to make sure you get the one for the small down pipe (if you havent changed it).
I have a hybrid Pac/BD unit on my truck, the brake and controls are BD and the air system is Pacbrakes new compressor and frame mounted air tank.

Hmmm. I wonder why I couldn't find those before.

Thanks guys. I'll check them out....

Best bet is to have the 4" exhaust elbow and you should be able to get a 04.5 and up kit then..

Dodgezilla

I do have the larger elbow....

ratsun

Ahh I see in your sig you put a 351 on.......did you put the 4" elbow and downpipe on?
If you did then order a brake for a 04.5 and up as it just takes the spot the elbow is in.

I thought there is an issue with some thrust washer in the 03 48re that kept it from working with an exhaust brake?

Dodgezilla

I remember reading something like that too a long time ago. Didn't Dodge offer the brake as an option but then discontinue it for the auto trucks for a period of time?
Also, is there any other difference between the kit for the 03-04 and the later kit other than the elbow/DP difference? I have the larger elbow AND 4" downpipe too (Of course)

ratsun

Far as I know, no difference.
A quick call to BD or Pac could confirm it though.
I wonder if the problem was in the early 03s that still got the 47re?
I ran a BD brake on my 98 47re but it had some upgrades internally with no issues?
Its hard on the lock-up clutch at low line pressure regardles of the trans but I have not heard of a thrust washer issue?

Dodgezilla

My recollection is that it was only offered for the HO trucks so it would have been a 48re issue. I'm too lazy to research it though.....

Yes, there is a thrust washer issue. When I upgraded my tranny I had the problem fixed. Dave Goerend hooked me up. You weld the outer holes up on a drum and force the tranny fluid through the washer to prevent wear. At the time my truck only had 38,000 or so miles and that thrust washer without an exhaust brake had a ton of wear on it. I sent the old thrust washer back to Dave when I sent my old drum back. I could of took a picture of it for you.

Good to know my brain isn't gone yet. I would have put one one if it were not for that problem. I have a 48re in a 03.

I brought this thread back to see if anyone is using the PRXB on a Georend (or other built) tranny with some mild fueling mods. Can anyone tell me if they have any shifting issues as far as having the torque converter locked during a shift ?

Shifting with the converter locked is definitely going to cause a pretty harsh shift. Now depending on what kind of power and what is done to your tranny sometimes you can get away with it, and in some cases it can break things. You don't have to run with the converter constantly locked to use an exhaust brake. There are controllers out there that will only lock the converter when you use the exhaust brake. That would be a better option than letting it shift locked up..
