: Shifting when engine not running

Does it hurt anything to shift the transmission (an automatic) between Park and Neutral when the engine is not running ?

I need to perform a precision park (fractions of an inch clearance) and I'd do this by rolling (pushing) the truck by hand (engine off) into position, blocking the wheels, and shifting into Park.
Thanks!

no, it just takes the park pawl out and moves the manual valve.

No big deal
