I recently bought a 2003 MB C320 with 90,000 miles. I had a pre-purchase inspection by a local independent MB Auto place. They told me the transmission was leaking a bit and recommended service.
I have not noticed anything wrong with the transmission, no shifting issues, no lights, etc, just a warning the mechanic gave me. (It's an automatic btw).
At the shop they told me the transmission fluid should be changed every so often and people don't like to do it b/c of the cost, and that's maybe why the fluid is leaking, they recommended service. But then I looked through the owners manual and it said the transmission fluid NEVER needs to be changed, That if you notice leaks take it to an authorized MB dealer, that's it- I've never seen such a short set of instructions for a whole car transmission.
I have not noticed any leaks, but I don't know what to look for and am not particularly savvy with that stuff. I am confused about the owner's manual saying the transmission fluid never needs to be changed and the seemingly conflicting information given to me by the mechanic. I had a friend say some of these cars have sealed transmissions, that don't need fluid changes? But he was just guessing.
What should I do? I just want to make sure I maintain my new car properly.
Thank you for any advice!
