I need to add transmission fluid to my 300e and am not sure what fluid to use. Any thoughts out there?
Thanks

That's a NO on transmission flushing on a transmission in general and especially this nice and well made. Dex IId was the original fluid, but most have made the leap to Dex III with no problems. However, there's much controversy around backwards compatibility and Dex III. So much so, that a few of us switched to synthetics with the right MB spec #'s. My switch is still a work in progress, so I'd be reluctant to recommend....but at my mileage with an original trans, everyday it works is a good day!

No, the transmission wasn't spec-ed for synthetics, but that doesn't mean synthetics won't work in there.:thumbsup:
