Interesting how MB warranty is 4yr/50000mile bumper to bumper. Also interesting how they omit the tranny dipstick. No way tranny fluid is lifetime fill.

Past 4yr/50000mile when your tranny needs a rebuild, MB is off the hook. As many others have gone through, they never changed the tranny on a 5g-tronic which lead to a rebuild. However, none of these happened within the warranty period.

Is the MB tranny fluid synthetic?

It's ok to put crap in your car.
You will save $100-200 in 100,000 miles.
Please do and tell us the result.
But whats the point in asking us if it's ok to do what MB says not to? I've used non-approved motor oil, but I didn't ask everyone for validation. I did it, sent out a sample for analysis and posted the result, which were good, but not definitive.

Get real. This isn't group therapy.

The last couple days have been too rich!!

Crack?
Crack kills...well except maybe in this case.
I could be on crack too if was Heidi's. Yum!


OK, maybe we should all lighten up a bit. Whatever.
Are we sure this isn't C230_617 in disguise?
I will not be baited anymore.
Omitting the dipstick? It was never there, therefore it couldn't be omitted.
But you can buy one for 50 bucks.
The M271 engine doesn't even have oil dipstick.
Mfg,'s don't want us to work on our cars, don't release repair manuals till the car is out of production, vs. back in the day my BMW320i came WITH a toolkit, and even instructions in the owners manual on adjusting the valves.
Things have changed. It's like my neighbor said, when I had the alternator, supercharger, and various components laying on the driveway...
"I didn't think you were SUPPOSED to work on those car" Yes, just sign away your 1st born child to pay for repairs.

Luckily we have the forums.

Yes - signing off!!!!

I'll be doing my gear oil soon, I mean I'll get it done. But saving few bux without knowing for sure if it is harless or not makes me wonder. I won't do that every day, so I consider these few bux as insurance.

Of course they're free to specify whatever they want to. I never said they weren't.

I just want to know WHY they insist on the claim that their $20/qt is the only fluid that meets the requirements of this transmission. There's either something unusual about the transmission itself, or the fluid. If the high fluid spec is just to get longer life between servicing (or not servicing at all) the transmission, then I want to know that, and I'll choose to service the transmission more frequently using a fluid with a less impressive additive package and perhaps a less refined base stock.

On the other hand, if the transmission has components made of materials that MUST have this grade of transmission fluid in order to survice under ANY service schedule, then I'll know that I have no choice but to use the M-B fluid.

YOU (or anyone else) have absolutely no requirementto do so, nor have I ever suggested a thing, and from your reluctance to even WONDER why the issue exists in the first place, I suggest that you stick with the OEM materials. I, on the other hand, enjoy knowing how my car is engineered, and why things are they way they are. Mercedes are not perfect; they are still a just a car designed with compromises, and aimed at an averaged target market. To suggest that they need no investigation into their inner workings is both naiive, and hypocritical of anyone whose car does not remain 100% bone-stock, right down to the brand of tire. I read no condemnation of the dozens of "How Do These 19's Look On My Car?" threads that appear here every week; no recommendations that using anything but OEM wheels and tires is foolish and asking for trouble. Yet somehow the thought of an alternative fluid touching the inside of a transmission is heresy.....

I read that as "I don't know the answer, so I'll pay more to avoid having to find out."

Not my style, really. I enjoy the learning process.

OK, now you're just being silly. What you're saying couldn't be farther from the truth, though I've nearly been lyched for asking if it might be possible to produce our own Sprint Booster for less than 50 bucks..well or less than 250 thats for sure. I produced technical docs on the how the hall effect
throttle works, and I was nearly burned at the stake.

But seriously, yer going over board.
Heresy?
You stand accused of being silly.
How do you plead?
I, as judge, jury, and executioner, find you
GUILTY! Burn the witch!

Granted there are some lamearses around here...but if you stick around long enough, don't make tooo many generalizations about US members and don't get banned, you'll see whats the wheat, and whats the chaf.

Since you're so interested in learning, and don't like whats been said so far,
let me ask you to ask yourself this.
What have YOU contributed lately?
Think about it, before you rip into the OG.

They don't! Are you partially illiterate? - please get someone to read this to you.

Quote "I'm saying buy an approved fluid that has been through the MB testing & approval process. You have a choice of about 12 from, Chevron, Texaco, Shell, Pennzoil etc. etc. They are not exorbitantly expensive. MB seem to charge too much for their fluid that is, after all, made by a certain major for them." unquote

I repeated this a number of times.

I'm off to sunny Mauritius

i assumed from you statement that a engine that is more maintence heavy, would require a higher cost given more materials being used on a more often interval.



I understand your point of view, and retract my crack comment.

The stock fluid is fine for longevity. There people close to 200k here in mileage using the stock fluid. In the end, no one saying you can't. You can try it out and let us know. We're just trying to protect you from spending money on repair costs because you decided to use transmission as a guinea pig.

Mercedes probably has one of the best automatics in the industry. There automatics were too good, hence they didn't put much R % D in duel clutch techologies and only recently have caught up.

There's a lot of techonlogy that's gone into mercedes auto transmissions to make the shifts as smooth and quick as possible.

I don't know on the non-amg class transmissions, but i read a while back that the speed shift transmission for the c32 is unqiue from other auto transmissions because its one of the only autos when at a stand still with the speed shift option engaged the the torque converter will actually unlock so it can go through the gears more quickly shifting at times similar to a manual. Then it would go back to being a locked during normal driving.

Then the article goes into how the electronics know when to shift and all that similar to what other manufacturers have. The unlocking and locking of the torque converter based on what driving conditions is required is what impressed me. I never heard of a auto being able to do that other then a cvt, but cvt completely different story.

Thats why i'm saying, these are not your typical honda auto transmissions. If you owned three hondas then you know there autos suck, when compared to the precisness of the shifting in there manuals.

I tried to find the article again, but a lot of the old c32 articles dont work unfortunately..

Anyways, it you want to do the research on different fluids then go for it.
