My wife has a 97 Saturn Sl1 with an auto. I don't know why but it's making a gurgling noise thats audible inside of the car at higher revs or in P and N. I checked the fluid and it's got enough fluid in it, not low or too high. The service engine light is on, and the only code i'm getting is a Transmission Temp sensor error and my chiltons manual has no record of anything like that and neither does Advance Auto, Autozone, or NAPA. Can anyone help me out on this?

 

please post actual code from reader

thx
