transmission cooler lines

[seventyx3]

I bought a pair of transmission cooler lines from Classic Tube for my 73 online.  They listed them as OE fit for 71-75 which I thought was weird but I got them anyway.  They didn't fit.  No amount of tweaking was going to make it work.  I have the originals and I'm sure they're are the stock lines.  I will have to pay shipping to send them back.  Long story, short; Try someone other than Classic Tube.

I have had great luck with Classic Tube.  Got a side by side comparison of the new vs old.

My truck has tranny lines from Classic Tube and they fit like a glove.
Seems odd that yours are listed for a 71-75.

Can someone post a pic of tranny line routing please?  These lines are definitely different side by side.  The product sticker says 71-75 1/2 ton th350 2wd line.  CTT1002SC  They are supposed to be direct fit prebent lines.  In 73 they ran next to the engine oil pan in a factory clamp.  I'm wondering if these are really for a 67-72 pickup.

Do you need to specify what trans they are going to turbo 350 or turbo 400 or do both hook up in about the same spot on the two trans, just a thought.

They are different between th 350 and 400 and 2wd or 4wd

I have their trans lines on my truck and they fit great!

They list them the same for th350 and th400 2wd.  I'm glad you've had good luck with them, but they're listed as 71-75 and mine don't fit.  Now I'll have to pay for shipping to fix their mistake and hope they send the correct lines.   Inline was more expensive but they list theirs as 73-80.  Anyway, buyer beware.

A bit late now, but NAPA sells poly brake line you can bend easily with your hands.  You can get a couple of 5' lengths and route your own.  I just finished doing this myself.  As long as you don't have a show truck, function is the key!  Remember top of transmission to top of radiator, bottom to bottom.

I have used classic tube several times-for my 69 Camaro, 75 K10, 75 K5 78 K5.  The only issue was with the 78, one line was way jacked up, clearly bends in wrong place.
