Changing from 1st to 2nd gear noise
 

Hi All,

So i just got my car back after being fixed from CEL issue. Everything is good except I have a question....shifting from 1st to 2nd there is kind of a rough tin can rattling noise that comes on but goes away (while giving gas) once ur in higher gears. Its not something that is there all the time. Also it is more prevelant with cold starts and I only had my car for a day before it had to go to the dealer for the CEL issue so i do not have a point of comparison for what is "normal".

Just wanted to know if you all have experienced this. I assume it is normal noise because my bro drove the car the other day and he didnt notice anything out of the norm. May be it is the resonator noise....:iono:

Thoughts???
