Geez....My brain is disconnected. Wasnt thinking about the "other stuff" connected to the radiator.

The trans requires MB only SYN fluid. No substutions. Is very particular about fill level. No dip stick in tube; is factory sealed and dip stick is a "shop tool" with hot and cold fill levels. Need to know temp of trans oil when refilling as that fluid is highly expansive. You may or may not have a drain plug on your torque converter. My 99 does, some dont.

Sans dip stick tool and way to accurately measure oil temp, some will precisely measure the amount of fluid that is removed cold and replace with like amount at room temp. Dealer uses SDS to access trans temp and dip stick to verify fill level.
