i'm getting my 91 ctd ready for snowplow season, and i was underneath it today and the trans lines are rusty and starting to seep threw and drip. only problem is all the parts stores say they can't get steel lines that size. where can i get steel line that size?

Try your local big rig repair shops or a big rig dealer. They should have or be able to tell you where you can get some.

Perhaps a machine shop or transmission shop?

ive had lots of trouble finding the correct size tubing. Is ours 1/2" ID or OD?

good question! i havn't taken it off yet to measure fearing it'll be who knows how long til i find what i need to fix it. i'm gonna call napa today and see what they can do, if no go there i'm gonna call young's truck sales in canton, oh. they are a big rig place but they were able to track down the piece i needed for my cummins fuel filter part where it screws on. i'll let you know. nobody on here has ever had to replace their trans lines??

The steel lines are 1/2" OD. I have never replaced one completely, but I've repaired them. I have 1/2" hose in those repairs.

over the years ive done many manual to auto changeouts All ive ever used is 3/8 rubber fuel line and brass barbs.

All the after market tany cooler use the same thing.

Or you could step it up a little and use hydraulic line

McMaster Carr carries 1/2" steel tubing. It's like $10 for a 6 foot piece.

what was I thinking

coppereasy to work with

Not quite so. I used 1/2" ID rubber to connect to the 1/2" barbs on my trans cooler. Easy to find if you look for it.

Just to help a little, I used 1/2" OD thin-wall stainless steel tubing from my local big-machine hydraulics repair outfit. Comes in 10' lengths. Easy to work with a tube bender.
