Ford Transmission :: Severe And Sudden Leak Develop In Trans Cooler
Oct 19, 2013
I have a 2001 E350 van with the 4R100 Transmission. It had a severe and sudden leak develop in the trans cooler. The driver noted trouble getting the vehicle into gear, into reverse, but ultimately drove it about 25 miles until it stopped unable to go up a hill. Once stopped, the leaking fluid was obvious from smoke & fluid over the back of the vehicle.
It was towed to a local shop (not a transmission shop). They put 9 quarts of fluid in and started the engine hoping to see the transmission functional but only leaking from the cooler. Instead they found it not operational and no fluid coming from the leak. They assume the pump is ruined to the point of not pumping fluid at all.
Is it likely that the front pump is the only damage? Can I pull the unit swap the pump & put it back in service? What else (if more damage is likely) would a transmission repair shop find? What about a used transmission?

So I rebuilt my transmission earlier this year and its been working great, but I've yet to install a better cooler on it. I do quite a bit of towing with it, most of which is my boat. I've searched a lot on the forum here but cant decide on how to set up a better trans cooler.
I want a cooler that's going to handle cooling my trans on steep hills and such, but I don't want to completely cover my a/c condenser (I really like cold a/c ).
I've considered adding a couple of the frame mount coolers in-line and keep the factory cooler, I'm just not sure how well it would work.

I am adding an auxiliary trans fluid cooler to my C-6 in my F-250. Should the fluid route thru the aux cooler first then the stock rad cooler, or thru radiator cooler to aux cooler? Which stock hard line is fluid FROM the C-6 (HOT), and which is the return line (cold)?
Vehicle is 78 F-250 4x4 crewcab, 400/C-6

I pull a 23 ft travel trailer with my 99 f150 4.6l and so I decided I needed a trans cooler just to be safe towing in the dead of summer. I got a few quotes for right under 300. I couldn't justify the labor cost considering the cooler was under 100. So I made up my mind and decided to do it myself. I watched a bunch of videos for other makes and models but couldn't find nothing on my particular model year truck. I finished it today and I realized that my transmission fluid fluid is very dark. I have never serviced the transmission ever not even a drain and refill. I am going on my trip in about 7 days, and was wondering if I should even mess with anything to do with the transmission fluid. I put about a half quart of new fluid to top it off after the install of the transcooler but now I am worried that my transmission may not be in the best shape. Truck shifts fine as far as I concerned and acceleration is ok, so I am hesitant to do anything to it.

Can I change these out to hydraulic hoses with clamps that are rated for the fluid. Mine are rusted and starting to leak.

I have a 2008 Ford F250 V-10 Superduty and recently I had a transmission cooler line start to leak. I ordered replacement lines and the tool for the quick disconnect. The line that's leaking is from the radiator to the quick disconnect. I was able to replace the one line, however the second line (problem area) has been a nightmare. The line cracked right at the quick disconnect fitting.
The hard line is tight in the fitting and corroded. broke the tool trying to remove from disconnect. The line is flush with the quick disconnect. How to get that out of the fitting? or another method of fix? Its a hard 1/2 line going into connect crimped to rubber line going to transmission.

I've just (a couple of weeks ago) purchased an 03 Santa Fe. I noticed some trans fluid on my driveway a week later, and not a small amount. I took the lower cover off of the engine, and the leak is coming from the transmission oil cooler area. I had hopes that it would be something fairly straightforward to repair, so I got a replacement oil cooler and some spare hose, just in case it was just a hose. After getting the front bumper off, I found that the bottom of the oil cooler is clean and dry-- not the issue. It looks as though the leak is coming from what they're calling the Trans oil cooler "tube assembly", as illustrated on the Hyundai Parts Department trans cooler page as item number 5, part number 2547126011. Am I correct in assuming that I'm going to have to remove the entire radiator to get to this thing to replace it? It appears to be fixed in place, but I can't see any hardware to remove it.

I have problem with my Ford F-250 7,3 diesel SD from 99' XLT transmission 4r100 . I have changed torque converter and now something leaks between transmission and this converter. What can it be? Is there gasket which must be changed ? I didn't notice anything wrong with it.

Had a small leak on show up in my transmission cooler line at the radiator connection. After replacing the o-ring, which was pinched, I had lost some fluid up to about 3-4 oz. I had stopped by the local VW dealer and picked up a liter of ATF fluid and noticed the colors of the fluid differed from what drained out from the cooler line. Fluid that drained out was a cloudy darker green/grey and the new ATF fluid had a clear yellowish tint. Is this vehicle equipped with a closed loop cooling system or does it use the actual ATF fluid as the cooling medium?

I got in to the 92 Lincoln, shifted into drive, and noticed transmission slippage. I checked the transmission fluid. The fluid did not smell burned but was under the add a pint line. I added fluid to the full line. The car is worse. As you shift into drive, then you have to race the engine to get the car to move forward. The car will go up the block but not with any speed. It seems as if it is not developing enough power to get the car to move forward. If I throw the car in reverse, it drives normal. Is it time to sell the car to the demolition derby?

While fixing some trans leaks on my 6.8. I was tightening a clamp on the center cooler and the lines must have rotted. It snapped off. I was having problems with both attachment points. So guess it's just time. Problem is I cant find a good part number to order one. I can't find it on Rock auto. Here is a picture if it. It's between the front and main radiator.

About a month ago my van did the thing where it dumped four quarts of trans oil onto the exhaust creating an awesome smoke screen. I would like to avoid this happening again. I plan on adding a second trans cooler in series with the factory one. If the trans fluid goes through the radiator or trans cooler first?

My wife called today on the side of the road with a strange knock/rattle sound from the front (engine/trans/etc) along with an apparent loss of power. (no prior warning signs -- just started) She wisely stopped driving, then called me, and we decided it would be wise to have it towed home.
(Let me take a moment to praise my wife who has always been extraordinarily attentive to the mechanical operation of her vehicles. I've always been the fleet mechanic, and if she has ever experienced anything out of the ordinary, she contacts me immediately. She's not frantic or unreasonable -- in fact she's fiercely independent -- she's simply a conscientious person, and I love that about her.)
So we get the car home and I begin looking into what's going on. Was hoping it would be something simple like a motor mount or exhaust shield... no such luck. Everything externally seems fine.

This line is rusted out on my V10 and leaking fluid.
How hard/expensive is this to fix?
I'm in the middle of doing my exhaust manifolds right now, so I'm hoping it's a simple bolt-on fix.

I have Russell fittings and hose coming to hook up my new 6.0 cooler into my 5.4 powered truck. Have a question on the fittings on the bottom of the radiator for the cooler lines, first what is the 3/8" line called? Is it a double flare or what? And second question the female end that's into the plastic tank with the hex head does that unscrew or is it made into the tank? Trying to figure this out so I can overnight two adapters so I can get rid of the fugly hard line completely and use Russell braided line throughout my install

I decided to install a trans cooler since I was servicing the trans and got the pan dropped anyway. But when I cracked open the trans cooler connector(which is totally unnecessary and should be avoided completed), I noticed that I broke the trans cooler connector fitting to the radiator and now the coolant leaks badly from around the fitting. What are my options other than replacing the radiator? Would some liquid metal treatment do the magic? Or is there a way to remove and replace the fitting(I am not sure this would be possible since it looked like the fitting was welded to the radiator)?

I was searching for an oil leak forever. In my search for the leak I resealed my hpop, redid oilcooler rings and last week had a friend pull my motor to redo the pan gasket. The leaks were almost down to where I thought we had them beat. Now in the last couple days I'm losing coolant and oil....bad. there is oil on the ground mostly from the cross member. Question is did my oil cooler fix not take? I have read that a nicked of ring can cause this.

So changing the oil in my truck the other day, I noticed the exhaust clamp at the union between my down pipe and first section of my exhaust has been rubbing the trans cooler line and there's a Nick in the granny pan. Lookin at the rubber grommet on the hanger, its stretched tight and looks like the exhaust has shifted over. What could have done this or possible fixes?right by now it's got a gob of high temp silicone acting as a stand off. Don't wanna put the new line in until I have the situation remedied.

I have an 04 ford explorer, with severe coolant leakage. I am far from an expert but it seems like it's coming from the center engine block, but I can't get much access in to tell. What's going on?

I have read that the torqshift 5 speed in my 08 f350 he a thermostat in it that opens around 165-170. Is this thermostat to limit/stop the flow to the trans cooler? Does the trans fluid still move freely in the trans (pan, torque converter, valve body, ect), or does the thermostat restrict fluid movement inside the trans?
