My local MB dealer here in Michigan sold me Valvoline Dextron III for my 1994 E320? I thought that I would go to the dealer and get exactly what my transmission required.

I know there has been much discussion on this topic, but I am new to the MB experience and want to be sure before change something so critical as the trans fluid.

I called Merecedes and they stated that I could use any Dextron III and that Valvoline ATF Dextron III is approved.

Then I called the dealer in Indianapolis where this vehicles trans fluid was changed twice already. The service department stated that they use MB Dextron III in my car previously, but that I should use any Dextron III. "Dextron III is Dextron III", he said. Am I being paranoid?

Should I use Val Dexton III or buy something else? Your input would be greatly appreciated.

Thanks,
John
