How often should you adjust the bands in an Automatic Trans?

I have an 03 2500 and was wondering how often I should adjust the bands in my transmission. Any advice?

Check your service manual you got with the truck. It will tell you at what miles you need them adjusted.

I do the filter, all trany fluid, and adjust both sets of bands every 30k miles. 100k and like brand new inside. lots of towing.

It’s refreshing to hear from someone who takes care of their truck. I don’t flush my trany, but I do pull the plug on my Mag-Hytec and do a drain and fill every 15,000 with Amsoil ATF. I also have a 22 micron spin-on trany filter. The bands get adjusted every 60,000 miles. So far my truck still shifts like it did when it was new. I only have 78,000 miles on the truck, but I know people who have had trany problems way before I have.

I have 73,000 miles and I think I could almost fall into that "tranny problem" category already

Tthe Smarty S06 and 38's are your tranny's demise even with the stage 2 in it.

To the OP. I have never flushed my tranny and have never adjusted the bands. Every 30-40k I drain the fluid and change the filter. It takes 10 quarts each time I do it since I have the Mag-Hytec DD pan. I have 169,000 miles on my tranny. Two months ago I towed 20K combined from MD to TX going the northern route and it still performs the same as it did when I bought the truck six years ago.

Im in the same boat as Navydood. Trans fluid and filter has been changed once a year and thats it. Never had a band adjustment and has never had anything wrong. No funny shifting or anything. Still works like new. 178,000 miles on mine.

Let me clarify a little. I took the truck in at 60,000 miles to check the bands. The dealer said the bands were in specifications and did not need to be readjusted. He recommend that I check the bands every 60,000 miles. The 48RE seems to be a good trany for most of us.

Well the only reason I ask is cause I know the Auto Trans for Dodge are known to go out. My truck has 219,000 on it now and I bought it at 176,000 from my uncle and he got them adjusted at 165,000. I am about to make a move from Southern California to Jacksonville Florida and just figured it would be a good idea to do before I made the move. Thanks for the advice guys!

The automatic transmission behind any diesel engine powered pickup tend to be problematic. All it takes is a good rebuild by one of the big names and you will never have to worry about it again!
