As part of my attempt to keep this car on the road (2001 with 3.8L) for another year or two I need to address a small leak in one of my transmission cooler lines... I don't know which one is the inlet & outlet, but one of them has a slight drip leak somewhere on the side near the tranny or where the fitting is at the tranny... I figure it is best to simply replace both of them... I see the ACDELCO tranny cooler lines on RockAuto for about $20 each... What else will I need to do this (fittings, etc.)?... And how difficult a job is this to do?

When the car is warmed up, the hotter line is going from the trans to the rad, & the colder line is going from the rad to the trans. Sometimes after a long drive I'll put my hand on both to feel the difference. It's substantial. GARY

Don't push the ends of the new pipes through the C-clamps.
Position the ends of the pipes then slide the C-clamps in behind.

Are the same fittings used on both ends (radiator end and tranny end)??

I knew someone who did the do it yourself procedure of replacing the lines later to find that there was leakage at a radiator connection. He couldn't figure out why a new line was leaking at the connection there. I then learned he pushed the new pipe end through the C-clamp, spreading it too far apart, rather than sliding the C-clamp in behind the pipe end. I don't know if the connections are the same at both ends of the line.

The e-clip part # is ACDelco 24205103. Both ends use the same clip.
