Check the transmission

I see you have wrote your question months ago, but I'll answer it anyway just in case someone does browse through for information on the Chrysler 300 transmission. NO! There is no way to check your transmission fluid level on the Chrysler 300. Your transmission light should come on if there is a problem. Transmission oil is different from engine oil; transmission fluid does not burn up so if you ever did lose any transmission fluid it would have to come from a leak which you could hopefully spot if it is leaking. Lack of transmission fluid can cause slippage in the transmission which is a good tell tell sign. If you aren't noticing anything crazy with your shifting then everything is ok. Chyslers whole "theory" behind not having a dipstick is due to contamination when constantly checking oil. The transmission is completely sealed and you should just have a dealership change it whenever your manual recommends it ($150 - $200). I personally think it's a load of BS on their theory. How are you going to contaminate the transmission by checking oil from the dipstick?! That's why it has a FILTER! Maybe the guy at the Chrysler dealership didn't know and wanted to feel special about himself.
