Ok, so i jack up my car for a tranny fluid change on my 02 c230 and find the plug is a really big hex socket. Go over my tools, couldn't find any hex sockets or hex keys that big, so i measure the drain plug and its a 17mm. Head to Sears, bought it come home all happy, only to find the fill plug is a different size

. I STFF and find no info on the manual tranny. WHY ARE THIS GOD DAMN CARS SO COMPLICATED!!!!!!!, does somebody have the correct measurements for the fill plug?.

Before i go out of my mind with this car. Thanks!
