My only comment is that I just don't understand the financial agony that goes on over transmission fluid.

Let's assume a change frequency of 60,000 miles. Lets assume you drive 20,000 miles a year. The difference in price between the old special fluid, say $15 per liter and Mobil 1 ATF what $6.00 a liter is only $9.00 times 8 liters or $72 bucks. $72 dollars divided by 3 years is $24 dollars a year.

The new backward compatible MB Fluid is less than the old special fluid. So the difference is even less.

Why not just buy the correct fluid and save all the time spent trying to save a couple of bucks. After all it is a MB.
