4l80 transmission cooling lines and fittings

[erasedhammer]

So if I have a post '97 4l80, can the old cooling lines be modified to (at least) reach the new plug locations?
Both the 3l80 and 4l80 fittings look similar, but are they the same?
If not, are there adapters that exist?

And the 4l80e that I have does not appear to be quick connect, the plugs are threaded and so are the fittings

3sp and early 4spd lines and flare fittings are similar but 4spd lines are longer. The adapter for the 4 spd has a longer internal tube fixed on the adapter for one fitting. And is a must to use. Late 4spd are different, quick connect, non flare. You can bend the pipes and or add hose but why, they are not too pricey. When replacing big ticket items, consider replacing all flex lines and hard lines.

Thanks for the info, TedG. I'll be putting that to use in the next couple weeks as I get my install underway.
