I have a 1999 Subaru legacy Brighton the speed sensor sheered off so that just the threads are left in the tranny. That plastic stuff sucks Any Ideas on how to get them out. Also I had two p500 codes on my computer I know one of them is the speed sensor just wondering if any body out there knew if that would cause them both thanks so much!
