OK, well let's hope it doesn't change the dynamic friction coefficient or get imbedded in the clutch plate friction materials.

"Militec does not change the chemistry in the oil, but it make the metal surface 17 times stiffer(not harder)."

Chloro alkane (parrafin)
Will cause acid build up, Will lower TBN, Will cause corrosion.

So does anyone of these new ATFs provide a good match to the Mercedes ZF electronic 5 and 7 speed autos?

MolaKule:

Should I change my ATF at 30k when the OLM/MMS is programmed to throw the code at 60k? The transmissions are sort of weak in the past for my vehicle in which 3 years ago about 10-15% failed due to insufficient lubrication. They put jet packs to shoot the oil in quicker/faster. A lot of people are changing ATF more frequently as cheap insurance. Like I mentioned, the manual and now the OLM/MMS is set at 60k but previous gens, although maybe a different engine, has had it as high as 100k if not more for tranny fluid changes. I guess an inherent question I have is how do I see if the ATF is losing its protective additives either via the dipstick or some operating observations. IS there any harm I can actually do my changing it out in half the perscribed time then the manufaturer recommends (from 60k to 30k)?

I would change out as much as possible at 30K regardless of the OLM/MMS. Changing out a bit every 5-10k is ok as well.

Only a UOA would show trends in wear or oil degradation.

Terry Dyson can help you there.

Well Transmission are not made to last a lifetime.

They have many moving parts and sooner or later there is going to be wear.

For all the moving parts in a AT, Im surprised they last as long as they do.

True, what I was referring to was premature failures, or failures that occurred before the warranty period had expired.

What I should have said was, "I think poor enginering/materials is the main reason transmissions fail prematurely.'

Basically the same as above.

Most certainly and no one said it wouldn't.

ATF if a special hydraulic oil for the following purposes:
Lubrication for gears.
Cooling and heat trasnfer.
Transmiting torque via the TC.
Friction modification for clutch packs, bands, TCC.

If the oil is overheated, it oxidizes, chemical changes to additives occur, and the fluid won't protect the transmission.

If insufficient cooling prevails, clutch plates can overheat and distort, clutch material can break apart and disperse, and valves and clutch surfaces can be varnished.

Do you mean ECM control and faulty solenoids/sensors?

I guess if a solenoid got stuck and a low gear was activated most of time the temps could indeed rise.

Indeed, that's a control strategy to help speed warm-up on some autos.

Not sure of the question but note that Merc designs and builds their own. ZF is a HUGE supplier of the ubiquitous 8 speed found in Bentley, BMW, Jag, Chrysler, and many others...
