Trans lines

i have a 1975 olds cutlass supreme and the trans line is leaking where the line goes into the side of the transmission. It looks like a pop bottle cap and the line runs thru thAT and thats where it is leaking! how do i fix that! can i fix that place where its leakin or do i have to replace the whole line?

That pop bottle cap looking thing unscrews from the transmission. Remove that from the transmission and check to see if there’s an O-ring leaking at that connection.


ok ill try that and see thanks
