Here is what I was remembering. From the TDR site, Carlton Bale:
This was 10/03/2003. And later he posted :
So the Jan and Feb running changes might have changed some thrust washer, but not the thrust washer in question?

I just received official word from DaimlerChrysler engineering that an issue was identified on the 48RE transmissions that were tested with exhaust brakes. These were test vehicles that took a couple of trips out west (over the Rockies) and back. Apparently, the reverse loading from the exhaust brake caused unusually high thrust washer wear in at least one location.
At this point, I'm not sure exactly how this will effect plans to give warranty approval for the 48RE and the exhaust brake. I'm not sure if revised thrust washers or other changes will be designed and if they will be reto-fittable into existing transmissions.
I'll let you know as I find out more. At this point, I don't have a great deal of confidence that warranty approval of the 48RE and exhaust brake will happen by the end of this year.

I quickly read through the other thread. This is not the same thrust washer; the thread is referring to one that is loaded during positive power, not braking.

Ok so I've been reading this stuff about the thrust washer on the 48re. Im still not sure if it effects me or not, is it for the Jake brake people or all people, I bought mine to last forever not because I needed it, I never tow anything that is over 1K or so, do I need to be concerned?
thanks
thanks

I have to add my $.02 to this thread.
I am amazed at everybody's concern over the 48RE tranny.
Is it just because it is not E-brake rated? What auto trannies are e-brake rated?
Everybody used to holler about how bad the 47RE was, but in actual percentages, how many failed in normal(not bombed) trucks? I would have to believe only a very small percentage.
The 48RE hasn't been out long enough to even get a good feel for it's failures.
I think most people are making a mountain out of a mole hill on this one.

There are two issues that I see.
There is the e-brake issue. There were both hardware and software production run changes for it, and it's still not approved. One of the changes was with a thrust bearing.
The other issue is with the thrust bearing failing early.
My hope was that they were related. One weak part, found two ways. And that the weakness was fixed for later trucks. This does NOT seem to be the case.

My understanding from a PM from Carlton Bale was that a thrust washer was replaced in the 48RE in Jan and that another thrust washer associated with the 2nd gearing was to be replaced in Feb.
No other hardware changes for the E-brake was anticipated.
It will be as late as August before software has been tested and a reflash made available.
Don't know if only the 48RE's made after Feb. will be compatible for the E-brake or if DC will have a recall on 48RE's from Feb back for the 2004's.

at 27k miles i have just had the tranny rebuilt in my 2003 CTD 48re the dealer here in colorado cross referenced the washer part number and it matches the one now offered by the dealer in the rebuild kit. so i got a new tranny and TQ converter and the "upgrade" to the tranny. I was told the kit wasnt a second release but i dont know. do you suppose that the new trucks come with this new washer?.
just wanted you to know my experience with my truck and dealer.
im happy

I have a feeling I have one of the higher mileage 48RE's out there now... It's been treating me well and I only plan to run it harder in the next 6 months.

Did the dealer install a new tranny or did DC cover a complete rebuild? And what were the symptoms of the trouble? Nathan

Any updates on the availability of an EB for the 48RE. Trailer Life (March 04) indicates that DC was set to release "something" in Jan '04. ??
I am in the process of ordering a 3500 quad LB dullie and would love to have an EB to help a little on the downhills with my 7+ ton 5th wheel.
Any info or pointers would be appreciated.
Cheers Frank
currently 12 valve '96 LB dullie -- love it.....
