I am doing a trans, torque convertor drain and filter replacement soon on our E320. I was wondering if anyone has tried full synthetic or semi synthetic trans oils and what you think.
I have a 2001.5 Dodge-cummins powered and had the trans beefed up. The builder installed just Dexron 3 where the manufacturer called for a semi synthetic ATF +3. When I serviced it after the rebuild, I put back in the ATF+3. It shifted alot more solidly.
SO.... Can I run that in the MBZ??
