How durable is the 48re auto
I am shopping for a new diesel truck, and am going with the Dodge because of the Cummins motor, and am considering the automatic trans. The only towing I do consists of towing a 3 horse trailer full of horses over mostly level ground. I havent seen many complaints about the auto, but I am concerned that it wont hold up with the Diesel motor. Any one have any input for me?

The 48RE has been a very good transmission for DC. There have been several reports that the 48RE has the lowest amount of problems and failures compared to the torqushift (ford) and allison (gm). Very happy with mine. 1st BIG tow coming up. In hindsight, I may have given more thought to ordering it with 4.10's.

I just love it when an aftermarket product producer makes writen statements that turn out to be, well whatever.
Isn't he the same guy that said back in the early 2000's that a triple disk torque convert could not be made to work properly and was useless because he tried to make one and there is no possible way it would work.

I have a little less than 30000 miles on mY 04.5 Dually, most of the miles where pulling a 40 ft enclosed trailer from Minnesota to montana. I havent had anu problems with the auto In this truck seems to work great. I have a edge juce w/attitude and usallu pull in tow mode. I have 4.10 gears and that seems to work well.

I just completed a 1,500 mile haul from Denver to Nothern California. I hauled a 3 horse GN with two 1300 lb horses plus lots and lots of gear, putting the GN right at 10k lbs gross. The 48 RE was worked VERY HARD when I crossed the Sierra Mtns ascending and decending several mountain passes on Hiway 399 out of Redding CA. with 6 to 9% grades and what seemed like endless switchbacks. The Interstate driving from Denver to Reno on I-80 W. at 75 mph was smooth and effortless.
To alleviate your fears the 48RE has performed flawlessly for me to date!
I have 20k on my 04.5.

See my post on the TDR about my first BIG tow with the 48RE....I am Impressed.

Regarding DTT's comments about the 48RE, my understanding is that this so called thrust washer is in question WHEN used with an exhaust brake. It is also my understanding that this thrust washer was only used on early 48RE's and has since been changed.
These trucks stock have plenty of power and if you keep them stock with scheduled maintenance, you should not have problems with the 48RE. It is the best auto out there of the big three behind diesels and from I have seen, read and researched is the most reliable and has the least amount of problems of the big 3.

Tschwab,
However much I like my Dodge, I would have to say that performance wise the 48re is the worst of the 3.
Being essentially a 727 with overdrive (i.e. a hydraulically shifted 4 speed), there is no way for it to outperform an electronically controlled 5 speed.
This is why, bone stock, both the Duramax and PSD are faster 0-60 and 1/4 mile even though those engines have less stock power/torque than our CTD engine.

Yeah the 48RE has evolved from the 727 (just like the I-6 Cummins has evolved from 12V - 1st Gen, 12V - 2nd Gen, 24V - 2nd Gen and now in 3rd Gen a 24V HPCR). which was a strong tranny used in drag racing, there have been many improvements and it is a very strong and reliable transmission, having the fewest problems and being the most reliable in comparison to the allison and torqueshift trannys. BTW - My '05 48RE is electronically controlled, DC made a change to the '05, and I believe ALL 48RE's are electronically controlled.
Don't know if you have had a chance to tow with a 48RE, but it performs flawlessly. If your basing your comments on the 48RE for racing from stoplight to stoplight, your not using this truck for what it is intended for, which is towing and hauling loads.

Hate to burst your bubble.
But loaded with the same trailer i.e. towing), the 325 psd with 5 speed torqshift will out accelerate a 2005 CTD with 48re. Uphill, flat, whatever, it simply has more gear ratio being available to put the power to the ground.
I have towed with both (all 3 actually with manuals and automatics) and I still bought the CTD, so we are on the same side here.
However, you are dead wrong about electronic control on 48re's. The only parts of the 48re that are electronically controlled are O.D. and the torque converter lock up. 1,2, and 3 are hydraulically controlled. No matter what the computer says, the 48re will not shift until the line pressure is right. With Allison and torqshift, all gears can be electronically selected.
My comments were completely related to performance, not reliability.
