Transmission.
 

Hey guys. I did my oil changed and I did over fill so the screen was showing high oil. After that I went to walmart to put the oil at the right level. Now my car is not running well. To start up I have to press deeply the pedale to get get more power to forward and I have the check engine light on displaying the code P0700. My car truck is ML320 2001.

I think the info on the screen is for engine oil, I don't think anything monitors the transmission oil level. There IS a monitor for the engine oil level. Engine takes 8.5 quarts of oil.
Mercedes should not be taken to Walmart for service.
Especially for transmission service.
The trans fluid is special stuff, they do not sell it at Walmart.
