Hello
Do I need to change ZF 8 speed transmission fluid , if yes on which distance
Do I need to change ZF 8 speed transmission fluid , if yes on which distance

Yes, you do. ZF, the designer and manufacturer of your trans, recommends fluid change at 80,000-120,000km (50k-75k miles) or 8 years...whichever comes first. The shorter interval is for "severe service".

Best,
It takes ZF LifeGuard 8 fluid. MOPAR has their own re-branded version. It's pretty expensive at around $30/quart. Also, the filter is part of the actual transmission pan so you have to replace the pan as well. That alone costs a bit over $200 at Rockauto. On top of that, the process to check the fluid level is somewhat time consuming. So just in parts and fluid, you're near $500. If you're paying someone else to do it, I'd expect to pay 700-800 bucks all together.
So...2 of these:
Plus whatever filter is suitable for your car. For my scatpack, it would be this one:
MOPAR 68261170AA (available for $215 at Rockauto)
To get an idea of what a pain in the rump it is to check the fluid level, here's a handy explanation:
Best,
I changed the fluid in my 2016 8HP45 on 11/09/17 at 15,150 miles in my garage with the car up on jack stands and it was easy. There was a lot more crud on the magnets than I expected, but the fluid was clean (looked like green tea and had the same consistency). Checking the fluid level, while not as easy as using a dipstick, is also not difficult. I got the pan and fluid from Brian (BND) for about $250 and it has been flawless for 7,500 miles so far.
Changing the fluid in the NAG1 in my old 2013 was not any easier, in fact it was fairly messy due to the lack of a drain plug in the pan.

I have also changed the trans fluid in the garage on jack stands, so I would think something like this could also be done that way as well. Of course, a lift would make it way easier.
I watched the video. Several things bothered me about the whole procedure. One, that little allen bolt they use for a fill hole plug is pretty dang close to the exhaust. Looks like one could get burned while doing this thing with a warmed up car. And two, seems like as expensive as this fluid is, the procedure seems like it wastes some during the "warm up the fluid and let it drain out till it stops" step.
At the end of the video I thought I'd just get it done at the dealer rather than attempting it myself. (If I ever needed it done, that is) I've only got three thousand miles on it now, so it will be a while.

That train is never late.
I'm not sure I'd be rolling the dice on mystery fluid for my very expensive transmission. I'd stick with ZF's fluid, Mopar equivalent, or a commercial fluid that is compatible (in writing) with LifeGuard 8.
Brian, are you willing to reimburse costs to customers who have to sue if they are denied a warranty claim on a transmission issue if they use your fluid? Or will you just have it repaired at your expense?

**yawn**
Here we go again. Of course, we have no way of knowing if your fluid is compatible or not. Like your oil, it isn't certified by ANY standards body, doesn't carry any API/ILSAC certification, nor is it recommended by ZF or MOPAR for this (or any) application.
Answer my question. Are you prepared to pay if someone's transmission is damaged by your product? What warranty do you offer to consumers who purchase your product for use in an application that it is not certified for by any recognized body or the transmission manufacturer?
You're encouraging someone who has come here for information to intentionally risk warranty coverage if there is an issue with their transmission after using your products. I find that to be pretty irresponsible, but not surprising given your behavior here.

No, its a fair question. And I personally have no clue as I have never owned a car with a warranty on it. I just wanted to clarify that this wasn't about any claims what the BND fluid can do, but the what if scenario involving warrenties.
I could only wager that any of the bulk carriers have certifications or labels or whatever they are called that dictate they meet/exceed the requirements and that would be the argument a person would show to mopar in case of this scenario unfolding in a battle to re-instate said warranty.
Where as this scenario is/would be rare it is a legit idea and question. As stated, a guy lost out big time cause Chevy decided a Catch can was the reason why his still brand new camaro had an oil pump failure. Not the dealer but GM Directly. For some folks that's a huge hit on a new car. I never read rather or not the people who sold him the CC would help stand beside him and fight this absurd declaration of failure cause or not. Last I heard he got screwed. Bottom line, It's not what I think, you think, what BND thinks, it comes down to what Mopar (FCA) thinks. And if it happens what knowledge, routes, and information a person changing anything from stock on their car has when factory warranty applies.
From a Customer standpoint I think its fair to want to know rather or not the supplier would be there to help win a warranty battle against a shady diagnosis or just claim it is sold as a performance enhanced aftermarket fluid that exceeds criteria based on spec,and that the user understands that said supplier is not responsible for any claims of failure direct or indirectly related to sold product based on it's usage.

So then basicly NO AFTERMARKET FLUIDS should be used, no one but the dealership can do the service, Hell for that matter you better not even open your hood because the dealer can void your warranty if you do? I'm not sure I'm understanding why any aftermarket fluid companies even exist or could exist if this is the case.
Something doesn't sound right about all of this to me. I used to be a manager at Advance Auto and in all my years working there or as an ASE certified master tech I've never had 1 customer tell me how a manufacturer denied them warranty because of using oil A over oil B. Even Quaker Cake!
IDK, I must be missing what some here are saying.
I know about the catch can dude but to be fair Dodge voided a Hellcat owners warranty due to a K&N drop in air filter.
Lastly challenge to you both!
Mr.Brian can you please supply proof that your product meets or exceeds OEM Mopar ZF fluid?
Mr.Ritz can you please supply proof that the ZF transmission fluid marketed and sold by BND does NOT meet or exceed OEM Mopar ZF fluid?
Thank you both as I'm SURE both of you have laboratory test results to prove your claims.

I’m with you Ritz, plus I just learned he’s the reason for the very existence of this forum.
So I’ll see your “always jumping in unwanted” and I’ll raise you “I’ve been supporting this forum so thank me very much”

CE9311, How much does ANY fluid manufacturer stand behind their products? Do you guys ask these same questions to a rep from Pennzoil or Mobil 1? If not why not?
Brian just posted the specs and I believe it isn't the first time he has done so. And would you looky there they meet or exceed the specs required by Mopar.
So as someone famous once said "what the problem is?"
P.S. You've received from me the exact treatment you've given me, just as the meme says. If you do not like this treatment I suggest you alter yours. If you read more into my words then I write that isn't my fault. I would suggest that perhaps if your own attitude towards others wasn't so poor and confrontational you wouldn't automatically assume that's how others replies are intended. A glass half empty view of the world isn't the best way for it to be viewed.

I wonder why the 8 speed has shorter fluid changes than the NAG1 5 speed? For the 5 speed you only change the fluid at 50,000 miles if using your vehicle for any of the following: police, taxi, fleet, off-road, or frequent trailer towing. Otherwise it is recommended at 120,000 according to my owners manual.
The NAG1 5 speed has a recommendation of 120,000 miles if not severe duty. That is a lot of miles on a trans. Most people sell the car before that hits and the poor guy who buys it most likely does not change the fluid.
Again, will ignore the snide remarks from our resident sales guy. My comment about my personal warranty carefree lifestyle is that I've already gone to the "dark side" by using Rotella T6 5W-40 in my engine. Clearly not what's recommended by FCA, but I'm comfortable with it based on the other certifications it has and I had a fair amount left over from my Audi A8L maintenance. The difference here is that the cost of having to drop a new engine in my car wouldn't even introduce statistical noise into my financial situation. That's probably not the case for a lot of people.

I just noticed that Valvoline's MaxLife synthetic ATF also claims to be compatible with ZF LifeGuard 8 fluid.
