just finished mine today.Used the Dorman kit, it had new clips. Took me about four hours from start to finish and I'm glade to say I have no leaks. Thanks for the vids on how to's.

that info you gived on the after market clips was like the best words ive heard in a long time,had the same problem,THANK YOU.

Thank you for this. I have a transmission line job and man o man, those rusty lines makes me nervous

dinally the best advice on how to put a line in .with clip

I spent a little more and had some made with hydraulic lines and fittings. They were a lot easier to route around everything too!

Im in the process of doing repairs to this generation truck now - Transmission lines, oil lines, power steering lines, motor mounts, etc. Your videos have been a great reference. Have you ever done the fuel lines on this truck? I think that's next on my list after the winter

It looks like maybe lately you've been gaining quite a few subscribers. Maybe I haven't noticed until now but it seems like it was just at 12k. Love to see this channel grow

Cool video. I actually Just had my transmission lines that run to my auxiliary cooler replaced a few weeks ago by Mister Transmission. It wasn't too costly to have them do it, as I don't have the tools nor the garage to do a job like that in, especially in the tight places the cooler is in my F350. The lines in my truck were just the end pieces really, they were sweating through the lines and a lot of dirt and sludgy looking buildup was coating about the first 5 inches of line coming out of the cooler, and I also had the little cylinder shaped auxiliary filter for the cooler replaced at the same time also as it was coated in nasty crap too. I'm the sort of person that keeps a close watchful eye on all my equipment and taking serious mental notes of what to keep a close eye on and I like to replace parts before they start to cause me grief or problems. And my trucks never let me down before, or ever left me stranded so I think I'm doing something right. In my opinion if you treat your equipment the right way, it will more than likely show you the same respect also.

Go AC Delco on these lines. The Dorman I got from RockAuto didn't have the flare on 1 line. Kept blowing off. I ended up cutting and splicing the old end on to get buy. But will be replacing it with OEM lines and get to do the job twice.

those little black plastic “covers” help keep the line aligned and centered

Hey mossman love the videos man, keep up the good work. You should do led upgrades in the cab.

It's good to get that done now. I wonder what the book time is for that job. Would painting the lines help them last longer? I imagine so. But the equation eventually swings on how long you are going to keep the truck.

DO NOT REPLACE THE LINES!!! Just cut out old rubber lines and add 3/8" hose with 2 clamps on each end - easy peesy. cheap!!!

Yeah, I need oil cooler lines on my Yukon, but I know the Dorman lines don't last long so I'm holding off until I can play the $80 a piece for the OE lines. Mine aren't rusted just leak on the rubber sections.

I flush my own transmission fluid on my 2016 GMC Terrain. I'm going to buy 3 fittings to solve this problem. 1) ACDelco 15226661 2) Jiffy-Tite 31306 3) Jiffy-Tite 32106 The idea is that when I want to disconnect the oil cooler line, I just pull back on the Jiffy-Tite 31306. What a terrible and cheap design to inflict on loyal GM customers.

Aftermarket has a bad reputation for a good reason. LOL

great call!

great video thanks for the help

So you didn't replace the O rings in the transmission?

The factory parts leak too, doorman is the same part.

Im trying to do this now to a snow plow truck that spreads salt its a nightmare theres 1/8 of rust built up on it 😫

I recently did this to my truck but I used transmission hoses instead of the lines do you have a diagram of what hose goes where cause my truck won't shift out of park

That 3rd line that goes from top of the radiator to the front of the auxiliary radiator is where mine is leaking from. Working on a 2004 chevy avalanche 2500 series can't find the name for it or even a part at any auto parts store. Any good places to look for that item for my truck??

Does anyone know why such a high pressure fitting is just held in by a little clip I'm sure there's a good reason and I'd like to know cuz it doesn't seem to make sense to me why it wouldn't be screwed in does anybody know why it's like that?

Hey I’m about to do this on dads truck. Would it be worth getting new fittings at the trans instead of fighting with getting out rusted clips ?

what if transmission valve swap and accidentally installed in wrong direction do you think 'll keep temp of trans down ?

mossman, I've got a 2007 Silverado 2500HD 6.6L Diesel and I'm swapping out the lower transmission cooler line, which runs beside the upper line down the right side of the engine. They are attached to the block with a plastic clip. Did you have any difficulty getting the lines released from the clip and if so, how'd you release the clip? Thanks, CJ

ever see anyone use flex line for these lines? I'm about to do a engine swap on my s10 and the trans lines is something I want to change but I want to streamline them out of the way and flexible hose is easier to work with then hard line.

my dodge needs them. where did you buy them? the dealership wanted 235 for one line!

Does anybody know the part # for these transmission lines? I'm in need of a new set and cant find anyone local who knows

I did not like the Dorman lines,leaked.new lines,need new fittings. The new fittings come with clip and o ring,change fitting.

what I meant if install valve in wrong direction

You showed nothing, and talked me to death. PLEASE Remove This Video! Lol

I couldn't get through the video long enough to see a repair this guy yells his whole life story instead of just doing the job. Aghh!
