My car is a 2200 with 4t40e trans. My upper trans cooler line is leaking where it connects to the radiator. I ruined my old radiator by overtightening it thinking it was loose and cracked it. So after replacing the radiator its still leaking. I looked the line over and i cant see anything that would cause it to leak. Any ideas? I was going to replace the lines but i cant seem to find them at any parts stores. they all only have the lines for the 3 speed trans. Is there anything i should look for that would cause it to leak? Anything i can put on the connection to maybe seal it up? its not a bad leak im able to still drive the car, but i want it fixed since its a pain in the ass to check the trans fluid and i dont have any idea how low its getting otherwise.
