Installing lower trans cooling lines on 2006 Sierra!!! HO

[Buddy67Lincoln]

I have leaky lines so I replaced the lower and upper trans coolant lines on my 2006, 4x4, 5.3. I cannot for the life of me get the lower lines installed! I gave up trying to get the old one out and broke it to get it off. New one goes in all the way but I can't rotate it to get it into position. driving me nuts! I don't have a lift so that might be the issue is I cant get it positioned on the correct downward angle. I hit the ground...I dunno but its driving me nuts. Got the upper in no problem. I have tried installing from back and front and just wont rotate; gets stuck...any tricks or tell me I am just screwed thought more ground clearance. thank you

Where are you trying to get it off of? The tranny or the cooler/radiator?

This was the reason I went to traditional AN fittings

I had it off already, just trying to get the new one back on. The lower cooler line is the tricky one goes into the lower radiator.

I am just going to cut it, flare it and add a small hose with clamps to connect the two ends...done with this stupid 1 piece set up.

I used a 3/8" line splice on my trans lines. Cut it to spin the end around and connect to my new larger trans cooler.

 

No leaks at all.. seems solid.

Mine are 1 piece lines, but they are steel braided teflon lines. Same as I used to build for aircraft.

I never bothered with the steel lines. After mine rusted out, I just cut the rusted out section out with a tube cutter, then used rubber transmission cooler hose to repair it. Put 2 hose clamps on each end of the hose to secure it and prevent leaks... and done. Much easier and no more rusted lines.

I just installed new metal brake lines on a 2002 Suburban. In order to get them installed, I had to bend them in many spots, and then bend them back. It wont hurt the lines, just don't kink them. Make "soft bends".
