On my 2005 Outback automatic I occasionally need to wiggle the gear shifter in the Park position to start the car. Is there an adjustment for this or a replacement item?

I've had this problem on a couple soobs, seems to be three main things or a combination of them.

 

Yes the switch alignment on the trans is adjustable. Subaru says you need a special alignment tool to get it right.

 

The other factor is the shift cable, because that is adjustable too, so if it's not going all the way up into park that might do it. Especially if you gently ease the shifter into park with minimal force rather than pushing it firmly.

 

Third is the switch itself, these things do sometimes go flaky and then the car won't always start in park, or won't start in park but will in neutral, etc.
