47RE Transmission Problems

[CTD2003]

I would like to know how many have had any problems with the 47re mine has 70,000 + with no problems and every story I hear starts out "My cousins friends uncles fathers dodge with a Cummins and a 47re transmission broke down hauling a trailer or what ever";
What I want is who on this forum has first hand knowledge of a 47RE going bad?
What are the symptoms ?
What was done to correct the problem?
Have I just had good luck or is the 47RE failure a Myth! If so lets BUST IT;

I had problems with the wifes Hemi with this tranny. At various times would just go into limp mode. At that time nobody understood what this was all about. Shut the truck off and restart it and it would go just fine until it did it again. Didn't leave any codes so Dodge said ther was nothing they could do about it.

So that had to be something in the electronic control if it would start working after being shut off and restarted? Did they ever find the problem or did it ever totally leave you stranded on the side of the road did this happen frequently or just sometimes? I’m really looking for the catastrophic failure where there was nothing that would help short of a tow and a transmission overhaul. How many miles were on the truck when this started to happen? My Daughter has over 100,000 on her 2004 Hemi but she has the 48re with no problems.

I guess I can say my 47RE has been good to me. It's got 103,000 miles on it with fluid and filter changed regularly and the bands adjusted. Since the injectors and smarty were put in its now starting to slip in lockup and I know it's on its way out.

Time for a GB billet tranny.

My problems were all right off the showroom floor. Frequency was totally at random, never could find a pattern. Sometimes several times a day and others it would go for days in between. Never did get it fixed, got rid of it and moved on. Dodge said they couldn't find the problem to fix it.

My troubles started with the TC slipping. When that started the rest went in about 3 months. The debris from the TC clutch was in everything.

So I would have to say the 47re is a pretty good transmission because I only received 4 replies, one with 103,000 miles the other one was the TC going out and polluting the Trans. The other two seem to be intermittence that no one can figure out, I suppose that the 47re then is a pretty reliable trans
Thanks to all for your responses.

mine has 97000 on it now without any problems, imop if the horspower stays within what the tranny can handle and the tranny is maintaned and not hammered on(powerbreaking and such everywhere you go) than it will probably be fine. the number one reason for tranny failure in my experience is fluid breakdown.

So no one has had a catastrophic failure or knows of no one first hand having one, I am feeling this rumor was started by the guys of the lesser trucks!

In 2003, we had 98.5 with low mileage, towing a 10k 5th wheel. We were just started pulling out of Watson Lake Yukon and the transmission failed. We had no warning - just died. The mechanic asked if we were using the OD and we were, but would turn it off on the hills. He said he's replaced lots and (mostly Dodges) because people would tow with the OD on. SO I got rid of the 98 and got a 2004 and tow with OD off!!

I service mine every two years.

@ ~68k pulling my 5er the tc acted like it went into the "n" gear. I took it to the dealer who said there was nothing wrong. I wanted a second opinion. A buds dad has a freind who owns a trany shop, I trust him. I explained what happened. He said it was probably a sticky something in the vb, and indicated it was something seen on Dodges at times. I had him go through the trany and install a tc to handle the hp the truck currently puts out. He installed a shift kit and said the bands where in awsome shape, so he wouldn't touch them. Short answer, I had stuff done to make me feel better for towing my crap. I have no issues getting hp to the ground.

I'm now over 105k on the first VP44 and have no regrets.

Oh, and the reason the tc was slipping was some goon put DD2s and an EZ on the truck.
