Ford Transmission :: How To Set Up A Better Trans Cooler
Jul 5, 2015
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 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?

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.

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?

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)?

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 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?

I bought an aerosol can of transmission flush to flush out the cooler lines in my Ranger before I put the "new" transmission in.
Well, the can says it has a 5/16" female fitting on the tube "to fit most common transmission cooler lines" but my truck has what I believe are 5/8" fittings (the tube nuts on the cooler lines were a 5/8" hex). The fitting on the can tube ALMOST threads over the flared end of the tube, but not quite (I just want it on there so stuff won't spray all over).
Went to the parts store, found an 5/8" female flare to 1/2" male flare and that was the closest I could find. I'll take it home tonight and see if it fits. They had almost nothing for a 5/16" flare.

I have a 2007 Ford Explorer Sport Trac v-6. This truck has been the bane of my existence since I bought it back in September, but I finally fixed all of the issues I was having and it's been great. But, today I discovered that during the most recent work, the transmission cooler line ( Ford part # 7L2Z7890A) was left unsecured against the tensioner pulley. Needless to say, today a hole appeared that gushed tranny fluid everywhere.
I have two questions please- First, need to find the hose diameter so I can do a quick fix insert long enough to drive 1 hr. home? Second, I read online that there is a fluid fill point on the passenger side of the transmission case, is this correct and do I need to be aware of anything else to add enough fluid to safely drive the 80 miles home?
I haven't lost enough fluid that my driving is becoming sluggish and hesitant, but I can tell it is very low.

My 97 AWD Aerostar bumps in and out of gear on very hot days. I've had the transmission fluid and filter changed. That repair worked, but it still shifts hard when very hot. I tow a boat. I always push the shifter button in to deactivate the OD when towing. I talked to friends who recommended an auxiliary transmission cooler. I looked on the van where one might be installed. I have a factory transmission cooler (oem factory installed).
The cooler is in front of the radiator. I don't see any room to add an additional cooler. The van has 145,000 miles. The van runs and shifts fine most of the time. The problem has happened only on very hot days. What I can do to prevent transmission problems. I've read that the AWD 1997s use a five speed transmission. 1997 was the first and last year the five speed automatic was installed in the AWD Aerostar.

I have a 04 that has 153k on it. 4" cat back exhaust with no cat. SCT tuner running a custom street tune. New FMIC with the extra tune on it. Head gaskets where done at 90k along with ARP studs. EGR cooler, The oil cooler was cleaned, New coolant tank. 1-new head and The cooling system was flushed at 90K. All done by the dealer along with some other items. Installed a bypass coolant filter at least 60k miles ago.
I have been having a no heat issue sometimes at idle this past winter and a mystery loss of coolant. I replaced the cap with a OEM one. I did a vacuum test on the coolant it held at 25 inches for well over a 1/2 hour. Pulled the egr valve it looked somewhat like tar inside not 100% dry. At startup it sometimes blows some white smoke and other times it's black smoke. I've had the scan gauge on for the last week to check my deltas.
Running 65mph the deltas stayed around 10 degrees diff.
Running 70mph the deltas stayed around 14-16 degrees diff.
Yesterday just running around rural roads 55mph and under the deltas stayed around 10 degrees diff.
I have not found a lower pressure gauge to do a coolant pressure test.
It does look as though it has burped the cap. Because of the deltas I'm thinking a plugged oil cooler my be the problem.

Transmission oil cooler line, lower one, is leaking. I think to use pvf, black ones, brake line instead of new transmission oil cooler line. I did replaced upper one with new transmission oil cooler line before a few years and it is rusty already as those line are only zinc plated as opposed to plastified brake lines.

Is it suggested for transmission cooler to replace the small stock one? I'm going to get towing stuff soon and just want to make sure I'm not smoking my trans. There's a few I've seen....

As explained in the photo annotations, I can't figure out how to remove this line from the radiator so I can remove the radiator for cleaning.

06 6.0 How do I remove the trans cooler lines from under the truck? I've got the lines hanging free they're unscrewed from the transmission and trans filter but I can't seem to snake them out to replace them. How is this accomplished?
