06 Dodge 3500 Dually 48RE died..

[mikewats]

After towing my Carriage Cameo for 71,000 miles my 48RE transmission died. Lost 2nd gear. I just had the transmission rebuilt with a billet shaft, must stronger valve body and TC. Cost to rebuild $4600.00. Hopefully with all the beefed up parts this will last a while. Would love to hear if anyone else had transmission troubles with a 48RE.

Thanks,

MW

they are out there, over rated like aftermarket deeper transmission pans. built my tranny on the old 2005 ram, did not get caught up in the hype of a "billet flex plate" or the deep tranny pan. the old girl dyno'd at 500+hp and 1100ftlb torque

You are lucky, go buy a lottery ticket.

Do a google search.

We are snow bird and never use my truck in cooler weather. From mid April to mid Oct we leave AZ and travel across the country, half timers lol. I tried three times to install a bypass valve and they didn't work, trans got to hot. Must have gotten a bad batch?

You don't want too much cooling if you use your truck in cooler months. I've seen guys use bypass valves when running multiple coolers. You want the trans in it's best operating temp range.

And here is your billet flex plate. Over kill maybe but it costs just as much to replace a stock flywheel subjected to to much power as it does to R&R a trans. You will think you blew something up when you hear the noise a cracked/broken flywheel makes.

Billet flex plate

I'm just talking from my own experience over the last 13 years. Had the deep pan and still burned up two trans. Went to a Ford 6.0 32 row trans cooler (that thing is over kill) and I run 145° to 180° and 188° on the long hot grades. I pull 17K. The deep trans pan collects heat from the engine raising the trans oil temp. I've pulled a 5er now for 150K miles.

I'm curious, Is that 71k total miles or 71k towing miles? My 48RE has 85k and it functions well. I put on a BD extra capacity oil pan and I do a splash and fill of 7 quarts every 10-12k. I adjust the bands myself and am due again at 92k. I know I will have to throw money at it eventually but had hoped to get at least 125k. I'm only towing 10,000 pounds and only about 20% of total miles.

I'm at 94,000 on my 2005. The transmission is exactly like it was when it left the factory including fluid.

Not to start a war but the extra capacity pan's don't do any good. Your best bet is the largest cooler you can stuff in there! What trans oil temps are you running pulling the 5er?

They do a lot of good if you adhere to a splash and fill maintenance regimen. The drain plug transforms a messy time consuming job into a clean easy procedure. My transmission fluid runs 160-190 normally and will jump to 220 on a long grade in the summer pulling 10k pounds. Fluid looks perfect all the time.

""Whoever did the last band adjustment...$*$&% it up!""


^^^^^^^ This makes the most sense.

YEs a Billet flex plate was installed. I had the transmission services every 25000 miles. Band where adjusted as needed.

Good deal!

Very odd for a 06 to go bad at that mileage, especially with proper maintenance.

[garyp4951]

You should be good to go now. I did mine at 170k, and now has 220k.

[mikewats]

Yes the 71,000 is total miles, however I'd guess 60% of those are towing. I also went with a larger capacity pan.
