What trans in 1965 Barracuda with 273

Hi Folks,

I am new to the forum and new to mopar in general. I am working on a 1965 Barracuda with a 273 v8 and 2 bbl carb. I am going to need some transmission help, but first I don't even know which trans I have. What should I look for to ID the trans.

Thanks in advance for the newbe help.

Rick
