Few ways to tell! Generally slipping when changing gears. Maybe when driving, doesn't seem to shift into next gear for a longer period of time or not at all. Pull Trans. Dip Stick- smell burnt fluid? That's a tell tale. The Harmonic Balancer is the balance of the Engines Crankshaft internals. If bad it would cause a lot of vibration when driving.
If you are feeling a grinding/vibration through the vehicle while driving and think it may be trans. You might want to check your Torque Converter (If Automatic).
