This problem can have numorous causes and on higher powered cars typically a broken input shaft or drive chain set is suspect. Below is a short list of potential broken or failing parts to cause it.
-Broken input shaft
-Broken drive chain or sprockets
-Extremely low fluid level
-Broken ouput shaft
-Clogged filter from excessive debris in fluid
-Broken oil pump shaft
-Stripped torque converter splines
-Broken Input clutch drum shaft
-Broken axle or CV joint
-Badly damaged geartrain or differential
Outside of checking the fluid level and axles there is not much you can do short of removing the transmission for a teardown to inspect the parts.
