Yes you can. That was determined from looking at the Fuchs and Shell technical data which I found on their websites. I also called the Mercedes dealership to verify this and they agreed that the 5535 could be used on the 226.6 transmission. Here's what doesn't add up: The Mercedes dealer (Parts Dept.) stated that their labeled 5535 was more costly ($25/liter) than their 5-speed transmission fluid which was originally made for the models requiring synthetic fluid, including the 226.6. I'm not sure about you're transmission, but I would assume so since you are moving up in quality. You may want to check with your Mercedes dealership if you haven't done that already. There's no logic to the dealership's prices -- They probably consider the average new Mercedes buyer won't shop around because they'll be bringing the car back to the dealer for servicing throughout the warranty period. Sky is the limit on pricing under those circumstances. That's a big negative for the public image of Mercedes dealerships IMO. At least for those customers who look into this and determine the pricing to be way out of line. If the factory was still providing maintenance for the first four years, you can bet those prices for 3353 would be much closer to the the internet price. Thanks for the tip on Fastlane.
