How To Replace Upper Transmission Cooler Line 2000-06 Chevy Tahoe

Take this cover off. You wanna take all these pushpins off. Just use a trim tool. Pop the center part up. And then underneath the rest of it, do the same with the other ones.

Now we take this cover off. Take this bolt out. Use a 10-millimeter socket. Now there's plastic retainers that hold the grille on. Use a Phillips head screwdriver and just push and twist. You only have to twist it a little bit. See how that's loose? And there's another one down here. That should be loose. And over here.

That's loose. And over here. That's all loose. Now just grab the trim and then you have to just pull it out over here. Now with all those loose, then just grab this panel right here and just pull straight forward just like that. If you struggle with getting your fingers in there, you can pull the light out. There's just two pins. Pull straight up. Pull the light out. Do the same on the other side.

Now we take these two lines off. Just take this plastic cover, slide it down. You can use a screwdriver or a pick tool. And there's a little clip here. Take that clip out. Use the pick tool. Slide that clip out. Do the same on this side.

And then wiggle these lines off. And slide it up and then do the same for the other side. There we go. With these lines disconnected from the cooler, now I can use a trim tool and just get underneath here. There's this cover that goes across here. We wanna remove that a little bit so that we can get the lines past it. So, we just push. Take this pushpin out right here. And if you want to, you could take this one out as well. Remove this wire. I'll just take this wire off this retainer right there. We can slide this out of the way. That way you can get the lines straight down. Now you just take this cap off right here just like on the cooler, that little cover. And there's a clip there. Just use the pick.

And slide that clip off. And just grab this line and slide it out. And now there's...these lines are clipped in right here, so take a pick or a screwdriver and just get those out of the clips. Even if you're not doing both of them, just move that one out of the way. And then this is the smaller one. Slide this one out. There we go.

And just slide this down. And some fluid's probably gonna come out. Just get a drain bucket. And just twist it. And slide it out.

Now take the new line and slide it over this crossmember just like this. And start to twist this up. Get this other line out of the way. And twist it in position.

All right. Lock that in. All right. Now take this hose and line that up. We're gonna lock it in place and then put this retainer over that. Now over here, you wanna put this clip in, put the line through this clip right here. Now you get that lined up with the cooler. And then lock it in. And then put this cover over.

Now if you're gonna replace that other line, you can do that at this time or just reinstall the other line. Lock that in place there. And then push these clips back in. The pushpin. Slide the wiring harness over here. Push that pin down and then push this wiring harness through that clip. Lock it in place.

Now take the grille and then just slide it position. Push these clips in on the side. Make sure all these line up. And take a Phillips head screwdriver and just twist these. And there's four of them. This just locks it in. All right. That's good. And take this bolt. Put that stud in and tighten it down. And put this cover on, line it up, and put all the pushpins in. Lock them down.
