just dropping the pan, and changing the filter does not get all the fluid out of it. there is alot left in the converter. a reverse flush will take 95-100% of the old fluid out. then you can go about a new filter and new fluid. recommend mobil1 atf+4 or castrol i foget who makes it though, its in a blue container. id also suggest a deep trans pan, and get a cooler put in too.

how many miles are on the truck? after you do this (if you decide too), then i wouldnt do it again for say another 50K. this helps keeps the internals as sanitary as can be.

The band adjustment isn't recommended by Dodge anymore. Why I don't know. Probably from too many quick lube places screwing up the adjustment.

If you don't know the history of the trans or how old the fluid is, then I suggest a complete flush, and then get the filter changed. Check with the shop doing the work. Some shops don't change the filter when they flush the trans.

I would assume that the QC has a 4.7 and hence no bands to adjust. I had mine flushed when I got it because I didn't know the maintenance previously done. If you drop the pan and change the fluid every 20,000 or so it should be fine. By the way, when they flushed mine they did not open anything so the filters were not changed. I dropped the pan and changed both filters at the end of the towing season to be sure.

It's not a bad thing to have them adjusted. Just like the shoes on your brakes, the lining on the bands wear out over time. The adjustment was supposed to keep them at the proper setting for good shifts. Like i said, not sure why Dodge took it out of the servicing procedures. The only thing I could think of was too many quick lube places doing it wrong and screwing stuff up. If you take it to the dealer and ask them, they may or may not do it. But if I was going to have it done, I would want the dealer to do it.

they should have. id say not to go back to them then. kind of redundant to go through all that and NOT change the filter.

got a question. if you had the rt done, and you know whats involved, why ask the original question in the first place.? im a little stumped here.

always a good point to start fresh when you get a used vehicle i think. change all fluids, and filters. then you know at least when stuff was done.

i was also told that a trans drian and fill every year is a wise choice. fluind flush i would bet every 50K is a wise choice too, cause just draining the fluid and doing the filter just doesnt get all the debris out. especially all the little fine particles.

Let me guess. Somewhere between 3/4 and not quite full throttle it will seem like it tries to shift, and then drops into neutral or maybe back into 1st unless you back out of it?? Mine does the same thing. Easy fix. WOT all the time during acceleration. Or I just don't go past 1/2 throttle when speeding up. Lately for me, it's been keep it under 1/2 throttle because for some reason my torque converter doesn't like to lock up at all if I go WOT until I get to the speed limit.

As far as the lazy between shifts, I have a shift kit in mine, plus I tweaked on the TV cable to get them where I want. I highly recommend a shift kit to help extend the life of the trans. If installed properly, there will be less slipping between shifts which also means less wear on the bands.
