It really depends, but it definitely could be over full.
The reason I say "it depends" is, how did you take the fluid reading? Follow these simple guidelines to see if you've gone wrong:
- Ensure the engine/transmission is fully warm (which you did by driving 30 minutes).
- Ensure your vehicle is on level ground when checking.
- When you pull the dipstick, wipe it off with a rag first off, then restab the dipstick into the tube fully, then pull it right back out to check the level.
Step #3 ensures you are getting the "now" reading and not splash up which may have occurred during use. It will leave a more defined line on the dipstick that way as well. What you are showing in the pictures leads me to believe you may not have done this when checking.
If after checking the dipstick following these guidelines, the level still shows high, take it back to the dealership and tell them it's overfilled. This is very important because too much fluid in the transmission can cause it to blow seals due to over pressure. While the seals themselves are not terribly expensive, where they reside costs a lot in labor to replace them.
