Re: 2005 envoy SLT 6 cylinder
Why do you want to take the trans lines out of the cooler? They are not hard to take out, the problem is getting them back in.
They have a little plastic piece that wraps around the line, I'm guessing to help prevent corrosion in this area. Slide that back, then they have a three sided spring clip in a groove, use a pick or small flat head to pop it out. And done.
Now to put it back in, the O-ring should be changed. I have pulled it out and not replaced the o-ring and regretted it due to leaks after breaking the seal. Then you have to put the line back in and reinstall the clip and hope you have it in the groove on the trans lines. I thought I had it in one time, turns out only two of the side sat right. Week later the wife called in a panic that smoke was coming from under the truck and it was shifting weird. Line popped half was out not allowing enough fluid to shift right and burning the fluid up on the exhaust.
