Does anybody know what color or # of splines the tranny speed sensor driven gear on a 94-95 mustang gt should have? Im talking about what gear the cars came with from the factory. I pulled mine out and it was a red 21 spline gear. is this right for original equipment gear ratio? I always thought that the speedo was off, but i was never sure why. i'm thinking that this may have something to do with it. By the way, what is the factory gear ratio of the 94-95 cars?
