The dreaded 48RE

It's hard for me to believe I've been on this forum on/off for 10 years now. WOW, I've learned a lot and gotten a lot of help.

I also wonder how much I got to worry about needlessly?

When I came to a decision to buy my 2004 Dodge I remember having a lot of concern if the transmission was up to the task of towing. I am now at 120,000 trouble free miles on my 48RE and I think it is safe to say it is up to the task of towing.

I'd guess that about half the miles on it were towing something, the smallest being a 3,000 car on a tow dolly, for a lot of years a 10,000# fifth wheel and even for a while a 14,000# fiver. To help the tranny I did add an oversized pan, and I've changed the fluid (partial no purge) 4 times. I've changed the filter twice. I've never touched the bands, though maybe it's time for that now. I keep an eye on the temps, and though worried I have let it run up to 220 or more for stretches, hitting 260 a few times backing a trailer up a hill. (Since then I use 4WD-lo to avoid a repeat).

We are on a road trip now (not towing anything) and the tailpipe just fell off... but the tranny is still running strong!

(oh yes, per what I read here I did lose a fuel pump... and I'm in the process of losing a front u-joint too - so not all the worries I read about were vapor in my case... and at this mileage I'm ok with a a few items like this)
  • 163,000 miles on my 48RE (04.5 CTD,bone stock) Had the bands adjusted once at 120,000.
    Regular preventive maintenance.
    Well over 100K pulling our 14k fifth wheel.
    I have been thinking about having it built up some,I may,or may not,do so.

    :E I have thought about it but usually I have a bad dream right after and settle on the middle one :B
    I think most of the problem child's are from lack of maintenance. Keep the ATF fresh and they will serve you well.
  • I went with the 48" donaldson to factory tail pipe

    glad you're not having problems; I have same trans...
  • I've been pulling 18,000 for 3 years now with my stock 48RE and I run my box on extreme (well over 100 hp over stock) 100% of the time. Ive had the box in it for 5 years and before this 5er I had one that weighed 11,000 and my boat weighs 4,500 so that was around 15,500. My truck tows probably 75% of it's miles. I have never done anything to the transmission and it is still running strong.(Knock on wood)
  • The 48RE is a good strong trans. Just like any other make, they suffer if a lot of power is added .
    FWIW, you really need to adjust the band. If you don't it will eventually slip and not only wreck the band but also destroy a very expensive drum that is no longer being made.
