When I was in high school, a rubber transmission cooler line on my ‘68 Malibu burst in the parking lot after school. After the torque converter emptied, the car stopped, blocking the gate, in a pool of ATF. Very embarrassing for a 17 year old. Later I patched the line with generic hose from NAPA, added ATF, and drove it for many more years.

Good tip. Just checked my 2014 with 155,000 miles, sits in my gravel driveway when not driving, almost no rust on those hoses and it looks really good overall. I hit them with some Fluid Film just for the heck of it (prevent rust on the steel lines).

[@greenmountain4366]

Thank you for all the information in all of your videos. Excellent stuff.

[@bobbbobb4663]

I question how much flex exists in those hoses at the bend radius of the rubber hose. If anything, the hose does a really great job of placing a lot of vibration onto the weakest spot of the crimp terminal.

[@sabinabrozynski9215]

I had this problem happen to my 2013 F150 2 years ago. It happened with 150K on the truck so a perfect example of this failure. A quick repair cost me $900 but the trans didn't last much longer so I sourced a good low mileage used trans and had it swapped in for an additional $1500. Except for this issue the truck has been trouble free and still runs well. This is something I'll be looking at to prevent future failures.

[@calholli]

If you just make a bracket and hard mount those connectors at the "crimp so that nothing can move--- then the only that left to flex is the rubber line. You can use the bolts that are there mounting the steel lines from underneath. A drill, a welder and a couple of U-bolts, or clamps to hold them from moving. You could probably even use heavy duty zip ties, if you just fab a bracket to stick out there next to those quick connects so that you can hard mount them.

Old school hose clamps on a hose are usually better.

[@toddwilmot4436]

Thank you so much. I checked my 2012 F150 by AT cooling line clamps and discovered both plastic clip "clamps" have stress cracks running across the bottom half where the hose is secured. This is obviously an age issue on the clip where the plastic is getting brittle from age and heat cycles. I will be going to Ford to get new clamps which I now need. In the meantime I cleaned the shell of the clamp with brake cleaner and applied JB WELD to strengthen the clamp at the stress crack until it is replaced. YOU REALLY have found a big issue that many trucks will be having. Need a better clip made out of metal. Well Done. Love your channel.

There is no warning, no seeps or drips, they are good until they are a wide open 1/2 inch line. Honestly I would just change them, I have had two in the fleet survive them breaking off, but I consider those flukes more than anything. I forget what year the first one was, I want to say 2010, the second one was a 2012 and it happened with less than 150k km on the odometer, broke 2 years ago. I would say you are on borrowed time with those lines.

[@--_DJ_--]

@@jeffcarroll3831 I would for sure have a look, I just don't think you will see anything. There are ways to remove that section of line if you are a bit handy (or cheap like me). I did a few on the older trucks at work, but they have all left the fleet at this point so how I went about it is a bit foggy. I think I used a hose barb-barb connector in the existing rubber on the long lines and ran rubber from the long lines to the cooler. They are not too expensive from the dealer though, at least not as expensive as I had thought. GM bends you over hard for lines like that from my experience, Ford seems to be more reasonable, though I do get trade price there so that is a big saving.

Ford would not cover the cooler lines under warranty as they said it was not covered by the power train warranty. Guess I should have gone until the transmission melted!

[@bryancondrey6457]

Aluminum...bend it once, bend it twice, throw it away. Based on what you could show in the images, it looks like some fatigue took hold in the quick connect. I suspect it will occur again in the same place unless something changes. I'm sure the quick connect was implemented for the assembly line, not for service. It might be time time for some racing inspired Teflon lined stainless hose with A/N fittings bypassing the entire hard lines from cooler to transmission. Kudos on the double screw clamps per end of your bypass line.

[@aninnymoose720]

until some shmuck comes along and cross threads the thing... modern cars kinda suck. not our fault.. fack...

[@--_DJ_--]

That is a nice idea, although more expensive than you really need, I would just do standard rubber line. The biggest problem would be the oddball fitting they have at the tranny, would require some kind of adapter to get to an AN line, though maybe that already exists.

[@calholli]

Yeah-- Those quick connects should be hard mounted to a bracket, just like the Steel line's are hard mounted. That way it only leaves the RUBBER to take the flex, as it should be. Those rubber lines are just too big and they dont' flex very well-- so it's transferring all the movement into the weakest link-- which is that nipple inside the quick connect. If you hard mount those connections at the crimp--- then nothing can move but the rubber. It's another part (being a custom bracket), but it's obviously needed.

Thanks Brian for putting this info out there , just a FYI , I have a 2013 F250 superduty (70K) and had the same problem as you talk about here. Lucky for me at the time I was pulling a trailer just down the street from my house to pick up a bucket truck body , when I backed in to the lot I noticed a wet spot trail on the ground which I shut the truck off right away , got under the truck and found the leak , the fitting had not yet broke off , so I wrapped a rag with a tie rap around it , dumped the trailer and went home , which once I got home I took the rag off and it broke off . I only lost about a quart of fluid , part of was in my driveway as I left that morning. But instead of buying the part as you did , I just cut it off and had some HP hose from another vehicle repair that fit perfect with some clamps . I have had no issues since . I also cut the other line too and replaced with a hose and clamp. Been a few hundred miles and I always check for leaks and have not seen any problems since. I have seen this type of issue with other vehicles I own and now I always do a walk around before I leave the house with the vehicle running. But yes like your customer it could have been a huge problem $$$$

you have a great channel. all business and info, tips, etc are helpful to us ford owners. i have 2016 f150 5.0 xlt. 88+ k miles. purchased new. until now the trans has been no problem at all. good shifts, no shudder, no clunks,etc. just a good working trans. recently, about two months ago, the trans temp shot up 10 full degrees C from what it has been running since new, even in hottest summer temps. it was always around 85- 86 C. out of nowhere it shot up to 96 C in air temp of maybe 25-26 C. no codes no lights. took it to the dealer thinking i was just mising something on the scan tool, but they said everything was in spec, nothing wrong. no slip, fluid topped up, engine temp good, etc. so i take it home and am nervous about it since it still seems high to me. 2 weeks later we go for a day trip of around 300 km in air temp of about 27-28 C. starting out it climbed to 88-89 C. then levelled off 86-87 C. everything seemed to go back to normal. so all good and i am relieved. have driven several times since and no problem, tran is same as new. today i go out for groceries. it's 22 C and still ok. but when the store the temp goes to 93-94 C out of nowhere. by the time i arrive home 20 km away its hovering 89-90 C. any idea WTF is going on that causes this. aside: i have tow pack so factory tran oil cooler and the related valve block on the front cross member that interacts with the cabin heater lines through a heater something or other solenoid. solenoid says no fault and opens/ closes with scanner. dealer says instru panel temp gauges correlate with sensor ouputs. in other words the idiot gauges are displaying correctly. my first thought was my thermostat was failing. second thought was the valve block on the cross member. i thought my engine temp was a bit high. somewhere 199 -212F+ if i remember correctly. would need to confirm that. i have forgetten the exact values. no leaks, rad and cooler clean. shutters open in park when AC turned on. but stay closed otherwise. i find that is strange. arriving home today they were closed after i parked with engine running. also, when new, high speed fans would blast at times when parked with engine running. they no longer do that. high speed fan never comes on only low speed. high speed works through scanner bi dir control. help!!! the last thing i want to do is burn up my trans because a dealer cannot diagnose and says it's ok as is. yes "FORD TECHS MAKE ME LOCO"!

Aircraft mechanic here. I couldn’t tell if the aluminum and steel are contacting each other but if they are, this is likely a classic case of dissimilar metals corrosion. I also do as much of my own auto repair as possible and your vids have been a tremendous help. Keep them coming and take care!

[@robertborchert932]

Bingo! Notice the rust on one side, and the aluminum on the other? The failure is right there at the transition. Dissimilar metals corrosion. The aluminum will happily sacrifice itself. This is accelerated by the presence of ions, road salt and water being the key. This video is a wonderful illustration of why these lines must be serviced and replaced before fatigue wins the day.

@@robertborchert932 You would think people who have been making cars for over 100 years wouldn't make such a rookie mistake but they did. Why is ford's build quality so inconsistent? Some years they make great cars and some years they make junk no rhyme or reason I guess?

[@robertborchert932]

@@andrewgordon235 The truth is simpler than this. Vendors. Nothing wrong with the design of the hose or coupling, nor with the cooler. Parts made to specification, but not knowing the other end of the connection. Different vendors making each half. There's a cost factor of course. An old school mechanic can tell you what will happen with dissimilar metals, we deal with this nightmare regularly. In reality, these trucks march on through some really shitty real world conditions. Seen it over the decades, as long as it lasts through the warranty period, there's a laissez faire attitude. And yes, this isn't isolated to Ford, it's a worldwide issue, sadly.

[@RSH592]

Sounds as though the lines should be changed every 60,000 Mike's before metal fatigue sets in. This will allow one to stay ahead of the dissimilar metal issue.

@@BlueOvals24 You could detect that leak with a sensor easily, not that I would expect one to be in the cooler system. Flow sensors do exist ya know, and so do pressure sensors. It isn't general maintenance to replace a line that isn't leaking or heavily corroded. Those lines go from perfectly serviceable (sometimes a slight weep) to completely sheared off with little to no warning to the driver. I have years of experience working on a fleet of trucks with these lines. I am guessing you have no firsthand knowledge whatsoever. I am not sure why you think being a jackass in the comment section is helpful, especially when you are blaming (in a separate comment) rubber for aluminum shearing off. All you are doing is proving how little you know about the problem.

On a 2012 I would say you are on borrowed time with those lines. Our 2012 broke there a couple years ago with less than 150k km on it, heavy salt area though, but the aluminum tends to do fairly well compared to the steel as far as corrosion goes.

[@mandersen7416]

@@--_DJ_-- thank you 🙏

[@higbeedoug]

Not doubting the metallurgy issue but we all know that as rubber ages it becomes more rigid and brittle. That being the case the vibration these hoses were intended to quell can no longer be accommodated by a dry/brittle hose and essentially transmits its now non-damping factor to the aluminum connector now doing a task it was never intended. Like tires & wipers, rubber components have a limited lifespan of their own and should be taken into consideration during routine maintenance.

Of all the replies that I read yours is the one that explains why. I thank you for your explanation.

Aluminum fatigue fails. Period. Eventually it will happen. On top of that, you have a large change in size of the aluminum, so potentially more stress. Those quick disconnects need to be made from steel... Now I have to check the '14 mustang...
