does anyone make replacement transmission stainless lines for my 2003 GMC Sierra 3500, 2 door dump, 6.0 engine and the 4L80 trans(?). mine are starting to leak and living here in NH they like salt and mine are getting rusted out? thanks for any info.

 

Have you considered replacing the cooling line ENDS where they are leaking? It's usually just the end seals beginning to deteriorate.

 

I got a lead all I have to do is see if it pans out.
thanks
