So in the process of replacing my tranny output seal, I found my speedometer sensor was missing its cap. Exposing all the grease inside. Has anyone seen this issue before? I did some searching, but didn't find anything.

Could exhaust heat have caused this? My car has an aftermarket downpipe with no heat wrap on it.

 

re pack it with black rtv. it will be fine. its the same thing that happens to the knock sensors. no problem

 

Yeah there's not a cap or anything on it, just a potting compound that leaks like the knock sensors do. As stated, fill with black RTV and go.

Great! Thanks for the info.
