Since some people are interested in Dual Range Transmission, I did some research on it and I want to know if I understand the thing right,
In Sep 1994, Impreza C model ( whenever they change the model slightly, Subaru Japan changes the model code such as GC8A, GC8B, GC8C, over there)
they installed "Double Cone Synchronized Gear" on the second gear. On WRX type RA in JDM, they installed that gear on the third gear
In Sep 1996, they installed the same one on the third gear in all the JDM turbo models (model Code GC8D)
Let me know if I'm right or wrong in understanding what you guys mean by "Dual Range Transmission":)
