    I know I can use copper lines but I still need to know the thread sizes to get the correct bushings to make the lines fit into the tranny. It would be helpful if anybody knew the exact size and or thread pattern. Not an about size thanks.

    i fixed my own problem the line is 3/8 and the thread is american but the problem id the threads arent deep enough on the new line so i had to reuse the old ends and reflair them onto the new pipe and it seems to have worked i have no leaks just incase anyone has the same problem.

My 1994 dodge dakota v8 magnum appears to be leaking what I think is tranny fluid around the front of the engine. Does anyone know what my cause this?


The tranny fluid could be leaking from a line or cooler if coming from the front of the engine. The fluid is usually cooled by the radiator if an automatic transmission and is cooled in the radiator tanks. It may also have an external cooler attached to the front of the radiator area that can also leak

New tranny in my 92 ssei now it has tranny fluid in the rad ???????


The transmission and engine are there own entities. Unfortuantly the radiator in some vehicles cool the tranny fluid. Its possable when the coolant lines were disconnected from the transmission or from the radiator, the seal was broken on the radiator where the line goes in from the radiator, so you wont see it because its internal. This will allow trans fluid to enter into the radiator. Be careful with trans fluid mixed with the coolant may cause engine damage. Your solution to the problem if this is infact the source would mean replacing the radiator, if you do this be sure to flush the coolant system to rid trans fluid.

I'm losing automatic transmission fluid. Is there any common history to support a theory of leaking transmission cooling lines?


I just checked for technical service bulletins and there is nothing for leaks from tranny or lines. Your vehicle is 15 years old if they havent been replaced yet it is possible it it just time to change them. Check where it goes from metal to rubber on the lines that is most likely where it will be wet. If itis wet there more than likely you'll need new lines

I have a 94 f350 2wd 460 auto how can i tell if i have a e4od, or a 4r100 tranny? and can a 2wd tranny be converted to a4wd tranny? thanks bob.

The 4R100 has the bypass cooler it is located on the passenger side if the trans. it goes from the rear cooler line follows the case to the front cooler line, and is attached with 7/8" banjo bolts. the bypass cooler was designed to keep the fluid in the transmission until it reached operating temp it "bypasses the cooler at the radiator until trans fluid needs to b cooled

Tranny radiator leak


If the leak is minor take it to a radiator shop and they can probably fix it for you for much cheaper than replacing it. Try tightening the hose, if it is leaking from the crimped end of the hose (where the hose mets the connector), then you will have to replace the hose. If you are getting green then its the actual radiator thats leaking and happen to be leaking trough transmission cooler vents.

My 1997 ford explorer overheated and the transmission slipped


Tranny fluid may have been contaminated with coolant since tranny cooler lines go to radiator or condensor.
I would fix your leak on radiator, then completely drain tranny fluid and filter and replace.

Transmission oil leaking from radiator


Either you have loose connections for Transmission cooler in rad, or your tranny cooler in the rad is defective. First, check the transmission lines and connections to the rad. If they are tight you'll have to either replace the rad or put an exterior tranny cooler on your car.

1998 Ford Club xlt, tranny fluid leak in the coolant.


The lines for the transmission cooler run to the reservoir on one side of the radiator, correct? You may have gotten a bad radiator and the trans cooler is allowing the fluids to mix.

I have a leak of my tranny fluid and I think its from my transmission cooling lines,radiator or the cooler. Should I install an auxilary cooler for the transmission ?


Most cooler manufactures and automobile manufactures information we have read, recommends installing the coolers In-Series with the factory radiator cooler for maxium cooling efficiency.

If you must bypass the radiator because the cooler tube is leaking or for other reasons, be sure to increase the size cooler you install by 1 to 2 sizes.

It is not necessary but will help in the long run. Expecially if you are towing or do alot of driving.
