Could be coming from your transmission cooler lines.

other places maybe rear seal(where driveshaft goes in), front seal(where the torq converter goes in which means gatta drop the trans), trans lines,

the leak looks like is coming more from the front of the tranny, its hard to tell where it is coming from exactly. it is leaking around the shifter imput, that general area. someone told me that there was a o ring seal for the dup stick that could be leaking, Possible? and it is leaking alot

The base of the dip stick could be cracked or the seal may have fail. You need to get under the car and, with a flashlight, look around (maybe take a few pics and post them so we can take a better look). What transmission do you have? We need more info on the trans.

i wold sugest is to replace the o ring for the dip stick. while you are there replaceing it check the lines because some times the trans lines will usually drip aand go on to that side. but do that o-ring first then see if it is still leaking. after that you may have a line or one of the main seals is going. the silverado that i have did the same it ended up being the rear seal allowing in air and the ail pushing the fluid up to the stick. what made me narrow it down was i replaced the o-ring for the dip stick then checked the lines and went ahead for the heck of it replaced the back seal. what i mean is do prosses of elimination first befor a possible full main gasket replace on the front and back. i really think it is the lines to be honest but do the o-ring for the dipstick it is alot cheaper than replacing one of the lines or doing both for satisfaction

i would suggest putting a few drops of UV dye in the tranny fluid to find the leak. i think they sell kits at any auto store that inlcudes the dye, blacklight, and maybe even some glasses. wipe any leaks off the trans, and drive around for a few days like normal. then crawl under the car with the blacklight (in a low lit area) and look around for the leak source.
