Having trouble finding depsteck on Chev HHR
This would depend on if you have an automatic or a manual transmission in your HHR. If you have a manual transmission, there will be no dipstick as it is only servicable from underneath the vehicle. If you have an automatic transmission, the dipstick should be on the driver side of the vehicle under the hood. The top of the dipstick will be colored in red most likely. If you are still having trouble finding it, I would recommend running a google image search for it. If all else fails, the transmission dipstick may be missing from the previous owner if you did not buy the car new. If this is the case, I would recommend ordering a new dipstick to replace it with so that you can check your fluid level.
