Take it out for a test drive and see how all the gear gates feel.
Adjust if necessary again (likely won't need to).
Sometimes the cable housings come out of the body attachment clips (under the heat shielding in the 'tunnel') and can flop around a bit ... requiring a cable adjustment.

Newer builds have a cable end where the lock pops out instead of in (as shown in my earlier posted pic).
