Transmission cooling lines with headers
What have people done for transmission cooling lines when using headers? 1970 Cutlass S with TH350. It looks like the transmission lines would normally go outside of the exhaust manifold on the frame, whereas with exhaust headers, the header is in the way. Maybe just hand bend them into submission? I have new replacement lines that would work perfectly with exhaust manifolds. Headers, not so much.

Yes, it seems that flexible hoses would be a great way to make custom routing for the lines. Since they are not under a lot of pressure, almost anything would be better than hard lines all the way back. Maybe some –6 AN to hardline adapters and braided lines might be nice.

I used lines for a 72 on my 70 and made a few bends to move them out of the way of the headers and the suspension. The 72 radiator has the top line port much lower then the 70, this helped keep the lines up out of the way.

Lots of aftermarket parts take the easy way out. When you are selling a one-size-fits-all cooler, it's kind of difficult to provide pre-bent hard lines. That doesn't mean it's the best answer. The factory RPO M55 aux trans cooler used hard lines. I find hard lines much easier to route, cleaner looking, and definitely less prone to damage.

I made and flared my own lines for my '72 442 convertible project. I wrapped both lines in heat shrink tubing followed by an outer layer of heat shield material where they pass close to the header tubes.

I ran them along the oil pan rail. 1 or 2 clamps using pan bolts, out the front and to the radiator. They’re visible under regulator, heading past idler arm and past the lower rad hose drain clamp jungle..
