my sc is not coming online . did some checking and found f2 fuse blown . replaced fuse , blew again .

changed out rcm , blew #2 fuse on new rcm . did some research and says f2 fuse controls sc and o2 sensors .

so replaced f2 fuse and disconnected sc . drove the car a few miles VERY easily 1/4 throttle max . checked fuse , good . drove the car again around the block this time pedal all the way to the floor , sc still unhooked. fuse blew .

so it doesn't appear to be sc , drive the car easy and no problems , jump on it fuse blows .

ideas ?

transmission ?
