Does it have a 4500rpm rev limit now as well? Here is some of the diagrams I have found related it. http://opposedforces.com/parts/impreza/us_g11/type_3/manual_transmission/mt_speedometer_gear/ http://opposedforces.com/parts/impreza/us_g11/type_3/manual_transmission/mt_transmission_harness/ In the last diagram I believe that is the sensors near the tail shaft of the transmission.
Doesn't seem to have a rev limit that low. Does however cause the fans to run constantly. It is the sensor right behind the bell housing on the passenger side. I just need to know how to remove the little plastic demon.
I have the full transmission manual saved on my computer let me know if you want me to email you that.
Thanks. I have the factory service manual too. Just wasn't sure on the removal of the part. Gonna see if I can get it loose with some vise grips. No wrenches fit.
Did you try soaking it in anything before hand? Kano Kroil in my experiences has worked wonders and loosening everything up for deposits.
