I understand that generally, MB doesn't recommend trans oil changes. I frequently tow a 5,000 lb. trailer with our '98 ML320, and plan to keep it until 300K at least.

I purchased the dipstick and the trans oil level is fine. It looks and smells good. Is there any compelling reason to change the oil anyway? 114K on the clock now.
