Rule of thumb… conventional spark plugs 30-40k. Platinum or iridium 100k

Coolant and brake fluid from 50K-75K.

Trans and differential 50-100k. If you frequently tow then 25-50k.

Always replace with quality fluids (synthetic) and OEM parts or better (filters).

FYI There is nothing wrong with "Preventive Maintenance" (PM). it will not hurt the vehicle to change something before the recommended milage interval.
 
I'm one for all the maintenance, all the time. There is usually a time component in the equation of fluid changes. For instance, on brake fluid most manufacturers are 2-3 year intervals, or X mileage.

I've never owned a car that said the transmission fluid doesn't need to be changed. I wonder if the huge cost for service would have turned off a lot of buyers, so Dodge just said its good for life? Say what you want about the DaimlerChrysler era, we wouldn't have this good of a Durango or the ZF without that tie-up.
 
Ha ha. They actually printed that in there? That's amazing to call it what it can be.
 
It don't hurt to change the fluid earlier than specs say. Not a bit. I've been a 100% "Dodge or nothing" guy since I got my driver's license 40 years ago. But im behind the times as I have no experience with anything that new.
Have to change the pan with a fluid/filter job?HUH? I have never heard of that one.
I'm pissed that I put a 46re in my wife's Durango in July and I am having to repeat it. The fact that I put over $180 in fluid thru that trans that got put in in July, the initial case of fluid it took upon install, and that filter, and then around labor day I replaced the governor sensor and solenoid, and a 2nd filter, and another 1/2 case of fluid. Those 2 filters (the later plastic cases style) cost me $28 each and are both garbage can filler, and now that I'm having to rebuild one of the 2 that I have (not gonna trust another junkyard one this time) so I'm gonna need ANOTHER case of ATF+4....
I ain't trading one problem for another by getting something newer ........ I started out in the 80s with vehicles 6-7 model years old, then I stayed 10-12 years behind, now I'm happy to stay 20 years out from current models when I hear crap like "having to" replace the trans pan on a basic maintenance job if it isn't leaking to begin with Dan’s Auto Repair in Port Charlotte.
I'm looking at having no choice but to buy a 4.7 because I'm looking right at the end of 318/360 production.... And not being happy about "that".

Guess I better not get comfy on the couch after work this winter and get my 78 fury caught up on maintenance and finish up the bodywork on my 85 D150. Those are still better vehicles than this new crap can ever hope to be.
At 60k miles, changing the transmission fluid and filter on your 2021 Durango RT is a good idea to keep things running smoothly. However, $800 does sound quite high. The cost can add up if they’re replacing the pan gasket and filter, but $450 for parts seems steep unless they’re using OEM or high-end components. It’s worth getting a few more quotes or asking if you can provide your own filter and gasket to save money. Also, a simple drain and fill without removing the pan is cheaper but may not replace all the old fluid.

And refilling the transmission requires some kind of procedures not generally available to the home mechanic, unfortunately.
