Not much to add other than all of a sudden, after performing my swap over 4 years ago, my speed sensor seems to be taking a dump on me.

Most importantly, the problem is inconsistent because it seems to work 2/6 times a drive the car in that given day. It will show signs of life throughout the drive etc.

Just a q?

-Is it common for speed sensors, or clusters to just let go after some time?

Its a type r hydro tranny, lsd and all that jive

I pulled the entire assembly and upon inspection everything was intact and in natural function.
