I'm been pulling my hair trying to get my car back and running. I just got my installed my transmission back on but I have a small leak. It seems to be coming from an electronic sensor. I'm not sure if any o ring is suppose to be there or if it is just suppose to click in. Or if it's soppose to be sealed with some special sealant. Any help would be greatly appreciated!

 

im sure there should be an o ring. all sensors ive ever seen had one

 

I bought a gasket kit that includes all rings. So hopefully everything seals up good.
