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.
View 3 RepliesThis 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.
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 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 my 2000 f350 is leaking transmission fluid from the cooler line. It goes to the rear of the transmission, but where does it go to from there?
View 5 RepliesI am going over this new truck I brought home not long ago. and I haven't picked a service manual up yet but I figure since I've owned manual tranny's before it's pretty obvious on the basics.
The fill and drain plugs are on the same side correct? I found them on the passenger side, figured the top one was the fill plug.. So I remove the plug and I get bathed in gear oil to the armpit and topcoated the driveway; Geesh the smell hasn't changed one bit.. I'm guessing the PO topped the fluid to the top of this transmission. Because I expected to stick my finger in the hole and either feel fluid or not. Not get a bath Unless I removed the wrong square plug.. I don't think I did.
What seals can I expect to be blown because of this if any? I haven't put many miles on it since I bought; it maybe a 100 total. I have no idea though how long it was driven though before I picked it up.
I have a '99 E350 that sat for a winter. When I started it up, it appeared to be overheating and boiling over. I didn't have time to mess with it, and it sat for another year. Today I tried to figure out the issue and determined that I have trains fluid in the coolant. Pulling the trans dipstick revealed a white milkiness on the dipstick, so I'm guessing the trans cooler/radiator failed and the two fluids have mixed.
My question is, is the transmission salvageable? The van has not been driven in this condition, so I'm hoping there is hope. Obviously, flushing both systems (multiple times) is in order, along with a new radiator. But is there any hope for the transmission? I'd hate to spend the money flushing it all multiple times if it is a lost cause.

Quick run down on the situation. It has been terribly hot here bumping 105 degrees. I was told by a man he could see fluid leaking and it was trans fluid. I checked it and filled it up and got it to the shop.
Next day they said it was not leaking and that it probably overheated. They recommended an after market trans cooler. They put it in and off I went. 60 miles later I got fluid all over the rear of the truck. I filled it up again and got it home. Shop says I need a new trans.
I've been running type F since I bought the truck about 30k miles ago. The dipstick says to run M2C138cj which I recently found out is NOT type F! I hope I haven't destroyed the clutches. How I can get all of the old fluid out. Also I can't find any transmission fluid with the ford M2c138cj spec is Dex-Merc III backwards compatible?
View 2 RepliesMy 1999 7.3l Disel 4x4 transmission quit on me the other day. No forward or reverse. Got towed to my regular repair shop, and they are treating the transmission as a black box and recommending total replacement. The diagnostics they performed were to make sure it was shifting, and that indeed it wasn't going forward or reverse. They drained the fluid and said "it's pitch black" and said it had to be completely replaced.
Fluid level was OK, and it wasn't hot. I was driving along, and merging onto the highway. It downshifted, shuddred, and nadda. Free rev. I coasted to the next exit and into a parking lot. Verified that it was shifting, checked Rev and all forwards. It wouldn't shift into 4W, and 1-2 also wouldn't move.
I'm trying to figure out what might have happened... and if it's worth trying to have the truck towed to a transmission shop and have them diagnose and rebuild, vs just getting a remanufactured transmission. None of the local wreckers have any used transmissions, and the cost between a reman and a used is pretty negligible...
Not sure what the symptoms points to for exact failure mode, be it the torque converter, pump, input shaft, etc... I've never had an automatic transmission apart before, but built plenty of motors and am a machinist by trade. My preference is to try and root cause the failure...
Tranny fluid spews out pretty good underneath. Is it likely a broken hose? Where do I start?
View 3 RepliesI cannot find the transmission dipstick to check the trans fluid? I looked in the owners manual also and I can't find it.
View 14 RepliesI have a 1997 Ford F-150 XLT 4x4 with the 4.6W and a 4R70W trans. For the past year is has been leaking trans fluid and has slowly got worse and worse. At first the truck would only leak at high speeds (when driving on the interstate for extended periods of time) and now It has gotten to the point where I am adding close to a quart of fluid a week. ( roughly about a quart every 300 miles!). I thought that it was the pan gasket leaking at first, so I flushed the trans fluid (dropped the pan and drained the TC and put on a new filter) put a new gasket on and torqued it all down and added some new Valvoline max life fluid. The first trip in the truck I noticed a puddle of fluid under the truck again.
The pan looked like it could have been a little warped, so I ordered a new pan and a new FoMoCo gasket (the one the came with the new filter was the cheap felt type). I thought I for sure had fixed the truck this time, but I drove it and once again it was still leaking. I checked all that I could before replacing the pan and gasket. I checked the trans cooler lines and fittings (no leaks) I pulled the inspection plug and it was dry (so I ruled out the front pump or TC leaking). The whole underside of the truck is covered with fluid so it is hard to pin point the leak, but most of the fluid drips down on the transmission cross member.
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.
View 10 RepliesAbout 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?
View 3 RepliesI 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
View 14 RepliesI 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)?
View 5 RepliesSo 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.
View 10 RepliesI live out in the sticks, and leaked out a lot of tranny fluid. the fill plug in the pan is rusted bad. can I add fluid using the cooler line and a pump? so i can drive it to the repair shop.
View 4 RepliesI 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?
