Speedometer Sensor Leak
 

I have a leak in my transmission that is coming from the speedometer sensor in my 915 transmission. I have the style in the pic because its been flipped for a 914. It was fine on the bench but starting doing this once I got it installed in the car. Currently the back end of the car is up so its tilted down towards the bell housing. I'm now on the hunt for a new o-ring (the ones I had were too thick) in hopes that stops it but was wondering about putting some gasket sealer on it as well for added protection. Any other ideas on this? I just replaced all other seals on this transmission and want to get this one stopped too.http://forums.pelicanparts.com/uploa...1600002761.jpg
