How to tell if you are looking at a 5spd transmission or 8spd transmission

Hello,

I am a newcomer looking at possibly buying my first Dodge Charger. I found on Dodge's website that the 2014 Charger SE comes with either a 5 spd transmission or an 8 spd transmission. Aside from looking at the mileage statement on the dealer sticker is there any other visible way to tell on the car if it has a 5 spd transmission or an 8 spd transmission.

I am hoping to find an 8 spd transmission SE but unfortunately certain dealer websites don't list the MPG's. I have been told the 5 spd is rated for 18/27. ...and the 8 spd has been rated for 19/31.

Thanks,

David
