I have a 2007 2500 hd classic with duramax and allison and I have leaky weeping fittings on tranny cooling lines which I have heard is common for oem lines..

What are peoples advice on whether to replace or leave?

Also what is the procedure and parts to tranny fluid replace,and internal and external filters? And threads or pics?

Thanks any info welcome

Replace these with some great aftermarkets, like those from Alligator Performance or some of our other vendors on here. Just wait....on one of the first real cold mornings coming up, start the truck up for warm up and then come back out 15 min later.....they wont be just weeping. Most likely straight up leaking.
