Hey guys. Did a tranny flush on my 6 speed yesterday and now I'm have problems. The temp gauge keeps maxing out! Sometimes it goes back to normal or even to cold but then back to max!! Pulled the codes with a pocket scanner and I get P0713 and P0713 pd. These aren't listed in my list of DTCs. I'm going to pull the paper filter out in about ten minutes. Also, I can put my hand on the bottom of the tranny pan and it's not scorching hot...it's warm but not too hot to touch. Thanks guys!

Ok, I been researching and it may be the trans fluid temp sensor or just the o-ring for it. Anybody got a part #?
