The fan clutch is not making the engine rev. high, it just could make it sound like it is. The fan clutch should disengage after a while, the roaring sound should go away. If it continues to roar, then it may need to be replaced. The way your trany is shifting, I would go to a trany shop to have that properly diagnosed. It may be something simple like a solenoid, or fluid and filter change.
Can my clutch fan make my car idle high and when it goes to another gear it revs up real high then shifts.
