Alright so I bought a new radiator for my auto 3k, It's a radiator for a manual car so obviously doesn't have any sort of transmission cooler so I was thinking about just putting a cooler on, is theere any way I can mess my transmission up with the cooler?

aftermarket? im pretty sure no and it may be better cause your using cool air to cool the fluid not hot antifreeze

I mounted one in right front wheel well that receives air thru opening where yellow arrow is pointing, which also was not connected to bottom of radiator (cooling coil was plugged up). It's been in there for ~ 18 years and over 40K + miles, it's never been a problem winter or summer in my area of county (Virginia) with temp ranges of ~ 15° F to ~ 100° F. Don't know about your temperature location, but can't imagine trans fluid could ever get over cooled especially with heat generated within transmission.

That's pretty Relieving to hear the cooler I did get is a little bigger than I expected but I'm gonna mount to the rad front dead center in my 97 bumper. My state gets a lil colder sometimes but nothing much compared to yours, thanks guys for the help install is happening Monday!

I'm in the install process right now and I've got a quick question, so the cooler I have Is mounting directly to the radiator and the ports are on just one side, top and bottom, oem was side to side, does it matter which line is where?

It shouldn't matter which line is where, as I can't imagine why it would matter which direction it flows thru cooler. It's not same as direction flow of cooling radiator with flow being limited at times by a thermostat. I didn't pay any attention to which line went where on the cooler I mounted vertically in right front finder area.
