I am experiencing some transmission slip issues and upon inspecting something things it appears the previous owner of the blazer had spliced the transmission line with rubber hose. For what reason I don't know. Well the splice is torn and leaking and I want to put out a new line on it. I bought a new line but the ends wouldn't fit into the fitting in the radiator. Went and bought new fitting and they still wouldn't fit. By they all go on the old lines just fine. Anyone know what I can do to fix this?

 

Go to a shop that can transfer the old fittings to the new lines, unless you can do it yourself.
