I have the same issue. My 2006 Ram 2500 have 82K on it. I bought it used and the first thing that I noticed was the shifting issue. The first time I tried to adjust the front band, the band strut fell into the pan because it was too loose already. I have talked to some people and basically they all suggested that I have the tranny rebuilt. My impression is that by tightening it up, you could get maybe a few months more life out of it but it is not likely you will go far with it. Rebuild with upgardes is probably the way to go. Wish I have all the tech details...Maybe slipping is not the right term. I've not noticed it slipping in any other gear. It just seems to not catch second very good loaded or unloaded. If I am going up and incline from a stop, I could easily over rev the motor, until it grabs 3rd. I did the adjustment like normal, and I can feel it catching 2nd better now. I figure if it was a "slipping issue" it would be slipping in every gear. From what I have read, this is a common problem in these transmissions.
I will start saving now.
Is it better to have mine rebuilt since its been a good trannie so far, or buy a rebuilt one?
Thanks for the advice.
Have you found a good trans shop yet? I am in southwest Houston. Haven't got a clue where I should go...
