Good job but I think this should be in the 3rd Gen area most of our trucks have the 47RE trany. They will want to know this for sure.

So is he saying that, if given the opportunity, we should replace the 48RE planetary gear with the OEM 47RE gear?

jughead

how do you repair the problem? if i remember correctly the early washer is a lot thinner than the 48re.

Sounds like it. Could you imagine if Chrysler had trannys failing left and right at the 50K mark on there trucks from a cheap part. I assume if the article is true Chrysler will release some kind of recall to replace or fix this part if dealers are seeing multiple failures in mass numbers.

The other question I have to ask is I wonder how this truck was driven and what kind of weight it was towing.

FYI

I build transmissions for a dodge dealership and I have not had a 48re apart yet but I beleive you would have to change the entire front gear train in the 48 to a convert to a 47. You could not just replace the rear gear and shell(but I may be wrong). I would not count on Chrysler turning this problem into a recall. I have seen many design flaws on there part before and never once was a recall issued. However if they start seeing many failures they will pinpoint the problem and send out a TSB or service info to dealer. I do know of somebody who did change entire front gear train on his 48 to a 47 and has had no problems.

Yeah this is interesting. I plan to talk to ATS today about what
fixes they may have for us.

I originally posted this thread on Thursday night under a slightly
different subject title "48RE problems/Info to share"
and copied the same link to the DTT site. Now the post is
no where to be found, and some of the identical responses
are included in this thread. Kinda weird
Was this thread combined with mine?..Usually if this is the case
it would be mentioned by the modulator.

The link most likely came from the Dieselram.com site it was started over tere earlier, more info there.

Not sure what you're talking about. However, I do seem to remember a 48RE thread earlier, I can't find it either. It must have been combined with another thread. Unfortunately, I don't now know which moderator may have made the change.

Either way, the info. is still available.

Sorry.
I merged the posts, since they were about the same thing.
Jamie(hellotbone) posted first, so I gave him credit for the link.
(he posted in 2nd gen, so I moved it here, then saw the other post, then merged)


Got sidetracked at work and forgot to mention the merge.


I'll go stand in the corner now.

Modulators...No prob...I thought I was loosing my mind.
Thanks for the explanation.

I visited ATS during there RMTDR open house today. 10-4pm
I spoke in depth with Clint the owner regarding the 48RE,
ATS mods, and to the PacBrake Reg Manager Bruce Beck.

Clint is the nicest guy...very patenice, and VERY knowlegable
on Mopar auto tranmissions. I printed out the DieselRam
article regarding the rear plantary fluid starvation issue and
the thrust washer issues. Clint will review the info I supplied
and I will call him later this week.

Details later...gotta run

Curious if the earlier 48RE's are the only ones to have this issue, the ones that lack the needed "hardware" for exhaust brake compatibility. The newer ones were in some way improved, and only are supposed to require some new software for the exhaust brake.

At least that's the EB situation I've read in the TDR.

Anyone know what the upgrades were?

Sweeper54

The other question would be -When did they start making the improvements?

03CTDCO

According to Carlton Bale a Cummins Engineer for the EB Div (Jacobs), one hardware change has been incorporated into the
new 600's. Another is scheduled for trucks built after Feb.

I spoke to Clint the owner of ATS Diesel Performance yesterday
in person during his open house for the Rocky Mountain Turbo Diesel Reg event. During our discussion I asked about the issue of fluid starvation and thrust washers and non factory approval of EB's on the 48RE's. Clint thinks with his ATS valve body mod the fluid and thrust washer issues will be eliminated from additional flow and pressure created from modifiying the valve body. He thinks the main problem for non approval in the TC itself. He did
not know if the 2nd hardware change slanted for trucks built after Feb would have a TC upgrade or not. A Cummins Rep was was also present during our conversation (didnt get his name)

The Cummins Rep said if Carlton Bale was hinting around about another hardware change, then we should listen to his info as he is well known to supply TDR members with accurate info.

From all the info I have been able to collect about this 48RE and what changes are needed to install a EB, I feel its not a easy decision for us. Even people who have already purchased trucks
with some of the updates (Cummins 600's/2004.5) will need to
dump down some cash to modify their 48RE to handle the abuse the EB can dish out. I say this based on info I have collected to date. If additional changes are in fact already in the 2004.5 48RE's then this may be easier than to accomplish. Maybe a update kit will be offered by DC for newer trucks.

Perhaps DC is making all the changes required to handle the approval and long term abuse from a EB. Until we offically hear from DC about approval I dont think we will ever actually know what changes were made to the 48RE itself.

Anyone have additional info to share ?
