Ok, I have a 1995 F150 4x4 with an E4OD automatic transmission and in am losing about a quart of transmission fluid a week. There is snow in our driveway right now and there are NO drops of transmission fluid in the snow where i park my truck. I checked the coolant in the radiator and there is no fluid in there.WHERE IN THE #!! IS IT ALL GOING???I am going to crawl under it tomorrow and see if i can see it leaking anywhere and if i can‘t find a leak i will be dumbfounded.Any ideas/suggestions on where the transmission fluid is all going would be appreciated.(P.S- The E4OD DOES NOT have a Vacuum Modulator)
The only thing I can think of is you have a pinhole in a cooler line that only leaks when you are driving and the transmission is under higher pressure.
Your going to haft to get it inside some where ,It needs to dry off and get all the snow and water off of it and then you will be able to find the leak, I would say its going to be around the cooler or the lines and its leaking going down the road , that why you dont see it in the drive way where you park.
Well if you're having to add transmission fluid once a week, then there has to be a leak somewhere. Your truck might have an external transmission oil cooler. It should be located in the front of the condenser and radiator, if not then the cooler is inside the radiator. What you have to do is get under the truck with a rag and wipe down the transmission, pan, lines. Everything where it can leaked out of. By cleaning everything,and removing any old fluid and dirt, if there were any leaks you would find them easier.drive it for a day or so and see if you can find any new leaks. If you still have trouble once you are done driving you, can put newspaper under the truck to see if any fluids leak out. Last thing you can do is wrap white paper towels or white paper around transmission lines, hoses, or tape it to the pan or transmission so if it does leak while driving you can see where it stains paper. Make sure don't put paper near the exhaust pipe.
