search is your friend ;p

My MY02 service products manual states that you can use either the
MB power steering fluid (PN 000-989-88-03) or an approved Dextron III ATF. The list of approved Dextron III ATF is as follows:
  • Castrol Dextron-III/Mercon ATF F-30341
  • Castrol Transmax M-22257/22096
  • Chevron ATF Dextron III F-30108/30159
  • Citgo Multi-Purpose ATF D-21571
  • Exxon Superflo ATF Dextron III F-30111
  • Havoline ATF Mrcon/Dextron-III F-30321
  • Texaco ATF Mercon/Dextron-III F-30321
  • Penzoil ATF D-22413/F-30110
  • Quaker State Dextron-III/Mercon F30161
  • Sunoco ATF Dextron/Mercon F-30176
  • Unocal Multi-Purpose ATF D-22413/22431
  • Valvoline ATF Type D
any Dextron III ATF will do...

If a search returns this information, I would post a new thread too. What good is this information? There are no model details, 2002? Obviously, MB has updated some things over the last 5 years.

The MB bulletin of 2006 states quite clearly that not just any Dextron III ATF will do.

I didn't see the 126's mentioned.
I always use MB fluids, even when I don't care to pay for them, Am I also waisting dollars?

I think the 126 would be in the group needing BQ 14600001, as it is a re-circulating ball steering box, but I'm not sure. I don't think it's a waste of dollars, it can be bit more, but the alternative expense is much greater.

It is a very very bad idea to mix Pentosin (MB ATF fluid) with Dexron ATF.

These two are incompatible and will kill the PS pump.

Now, while Daimler-Chrysler were together they developed ATF+4, which I believe was used as PSF on both brands....so it's important to check by the chassis.

The older Euro cars, pre 1996, used Dexron III. Dex 6 or ATF+4 is the newer replacement....some might want Mobil 1 ATF but not much to be gained over the other 2 synth spec OEM ATFs.

Let me know if anyone has more specifics on year and model range.

Dex III has been superseded by Dex 6. Technically, the spec doesn't exist...it's not licenced, but any Dex III is the same as any Dex III, I assure you with the exception of an old bottle of Mobil 1 ATF that still says Dexron III.
