CEL questions
hi im new here. 
got a question about my 1999 ML320
saturday i was driving from one party to another and at first i didnt see any lights on the dash but then later on i noticed the CEL was turned on.
so today i went to autozone and pulled the codes with a reader and got
P0173 - Fuel Trim Malfunction (Bank 2)
i did a search on the forums and it seems like a simple thing to fix
but i also go another code
P0700 - Trans Control Sys Malfunction
i did a search and only 1 result came up and wasnt helpful at all. what is that last code about and any advice on what to do about it?
am i gonna have to bring it to the stealership?

Try disconnecting your battery and let it sit for about 15 min. Then reconnect and drive it about 40 miles for the computer to relearn all the sensor readings. I did this on my 00 and the CEL did not come back on, the state inspection also showed no codes present after I did that.
