The newer Chrysler 300's have 2 options for the transmission. The one that is made by Mercedes does not have a dipstick and will require you to take it to a shop or the dealer to have your fluid level checked.
check transmission fluid level . then check differential oil level also that model ford needed additive in diff oil to stop noise was a ford recall on that

There is probably a leak in your auto matic transmission, check the level (just the same as checking your oil, but it is in a different place). You can buy the fluid cheaply from the supermarket.

Not using the dipsticks for the oil and transmission, while seeing leaks are a sign... Check your fuids and keep them clean and full or you will cause damage to whatever componenet relies on their respective fluids. Answer leaking oil is NOT sign of a bad transmission, its a sign of a bad/worn seal(s) or hose(s). more likely a sign of a worn seal or oil pan gasket. Actually it's a sign of money that will go out of you pocket, the more you can see, the more you have to pay. If you don't fix it, you may have to pay for the aggregates, eg transmission parts instead of paying for a small rubber seal.
The five speed uses ATF+4. The eight speed uses a special oil for the 8hp 45 transmission.
