It may be nothing but wouldn't hurt to check to make sure the fluid level is up to snuff? If it persists you could drop the pan and look for debrie. Any debrie beyond the fuzz on the magnets warrants consideration of a rebuild. While doing that change the fluid and filter. If you start experiencing hesitation/stalling/hard starting it could be the flex plate is cracked. The crank sensor takes its reading from the ring gear on the flex plate inside the tranny.
