Have 01 Legacy. Make clicking noise when shifting from park to reverse. Trying to understand what the noise is.

automatic or manual?

 

Auto.

are you hearing the shift lock solenoid?  

Or the Lock cylinder solenoid?

Both activate during the shift from P to R or D.

Could you give me some more detail as to where these two solenoids are located.

one is in the column attached to the lock cyl.  This one keep you from turning key all the way to "off" unless the shifter is in P

The other one is under the shifter.  it has to unlatch in order to shift out of P into a gear.  It unlocks when the brake is depressed.

It could even be a front ball joint, that was my first clue one was shot.
