Ford F-150 - 1997-2003 :: 4R70W Trans Fluid Leaking - Puddle Of Fluid Under The Truck
Sep 26, 2012
I 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.

I have a 2009 F150 that when I came home from Cabo Monday, had a big puddle of fluid under the truck. I took it to Ford and they said it was some type of bolt on the tranny that is nationally backordered for who knows how long. They topped off my fluid and told me I would be good to go till the part comes in.

I walked out to my car and there was a big puddle of tran fluid under driver side front. I think it might be from the drain plug.

The trans fluid appears to need to be changed. I do not know if it has been changed in the past as this 2001 F150 with a V6 truck is new to me and has 88K miles. I am wanting to drain the torque converter as well as drop the pan and change the filter. I am willing to take the risk of having to rebuild the transmission if the flush junks it up.
Three Questions:
1. Is there any issue with mixing the synthetic with ATF fluid as there would still be ATF in the cooler and other places unless I take it someplace and have it mechanically flushed?
2. Is there a way to determine if my 4R70W trans has a drain plug in the torque converter with out getting under there, looking thru the inspection port while some one is clicking the starter?
3. Is there any reason not to put a drain plug in the pan while it is uninstalled?

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.

I just purchased a 2000 f150 4x4 with a 5.4 automatic... it ran great for a few days and even ran fine on the 100+mile trip home from the previous owners house. All the sudden it shut down on the highway today. I could barely get it started again and when it did start, it ran like hell, bucking and jolting, almost like a really bad misfire. I could also smell trans fluid being heated up, so I let it sit awhile and then it fired right up. It drove for about a half mile and began to act up again. I threw it in second gear to limp it home which it died several times on. Each time I'd let it sit for like 15 minutes with the negative battery cable off. It fires right up after that but the problem quickly returns. Also the overdrive button doesn't work, and the trans control switch fuse (spot 29) blows repeatedly. Also the power door locks do not work.

I have a 97 F-150 and my Radiator fluid has been leaking very bad but hasn't been taking the fluid from overflow tank. Actually the new fluid that I put in the overflow has now turned a rusty color....

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 a 2004 f150 4x4 with a 5.4. i have been leaking some fluid for a few months now but when i check oil and transmission both fluid levels are fine. I crawled under and it looks like something is leaking near engine and trans meeting and fluid looks reddish making me think its trans. now this week I developed a whining sound when truck moves. Again I rechecked oil and trans fluid levels and are all good. i was going to check transfer case but it is way behind leak and dry.

The truck:
2000 4X2 F150
4.2l V6
280k miles/ some towing
The problem : The trans has a hard time getting into 1st gear. When you put it into gear you have to rev it to about 3k (when it's warm, 4k when cold) RPMs at which time you feel a definite engagement and it goes through the rest of the gears just fine. Once it's warm it will do stop and go traffic as long as you start it with the OD off.
The background : Orobably the stock motorcraft filter on there, and I don't think the oil has been changed in the life of the trans, but I do know that it's never been ran low on fluid. I took a gander at it and found a plug where a gear type speedo went on older models to be loose and leaking. tightened it up about two full turns. also noticed what looks to be a leak where the main case meets the output shaft housing. now I know neither of these are the cause of my headache but I do wonder if the second leak might be a sign.
The research : I've been looking for almost a week now for a solution. I've been all over TCCoA, Explorer Forum,10 pages of search here on FTE and various other Ford based websites and have come across a single thread with the same symptoms but the OP never came back with a solution.
The plan : A fluid/filter change (and flush) is definitely in the plans as well as inline filter for my own satisfaction. from what I've read the stock 1-2 accumulator is known to go bad on some of these and if I have the pan off might as well check anyways.

My 4r70w is having some issues. It drives/shifts fine in reverse, 1st and 2nd but wont shift past 2nd gear. Doesn't even act like it tries. No CEL. I dropped the pan yesterday and there wasn't any metal chunks or any other debris in the pan and only the normal fuzzes on the magnet and there wasn't even an abundant amount on the magnet. This is a junkyard trans that was put in before I purchased the truck (2001 F150 supercrew 2wd).
I've ohm'd the shift solenoids and they seem to be within spec (below 30 ohms) so i want to rule them out, but still thinking of replacing all 3 solenoids just to be safe. Also, the filter just fell out with the pan so I'm assuming that might be part of the problem. My next thing to check is the 2-3 accumulator and spring to see if its stuck or broken.

2000 Excursion 7.3 unk transmission
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 have a 98 f150 with 4.6l an 4r70w trans. I am on my second flex plate when I pulled the trans this time the tc was stuck to flex plate an the center of flex plate was busted around the bolts it has the remo engine in it but the studs on the tc were stuck in the flexplate I got them apart but it looked as if holes were off center on studs orded new tc an flex plate again. There is 1 bolt missing in top of housing an one was to long an didn't tighten up could that cause it to do it...

Took my '11 F350 CC 6.7 Lariat with 31k miles on it into the dealer to have the tranny fluid leak looked at. I noticed this leak a few weeks ago as the bell housing was damp with fluid and the bolts heads on the underside of the poly engine oil pan were pooled with fluid. It is a very slow leak as I have parked it for 3 days and there were no drips of fluid on the ground, just collecting on the grid like pattern on the oil pan. Checked Fluid level and it is also full.
Anyway, the dealer put dye in the tranny fluid and told me to drive it for a few days. I took it back in on Monday and called this morning for an update. The mechanic informed that they ordered a new torque converter and some other parts to be "proactive" because he believes the TC is the issue. I asked if the cab would have to be pulled and they informed that all the work could be done from underneath. Glad I noticed this before the B2B warranty expired because this would have been expensive. I will be THOROUGHLY inspecting the entire vehicle from top to bottom before I hit 36k.

I have a 2000 2wd with the 5.4 in it. I tow a travel trailer and loaded is 6500lbs. Today leaving the campground I had to climb an extremely steep hill as soon as you left the campground. No time to build speed. The old Ex made it, but I was definitely worried. The truck ran fine the rest of the 2 hours home. I went to back my camper into its spot to store, and smoke started coming out from under the hood. When I crawled under it, tranny fluid was leaking on the ground. A pretty steady drip. I let it cool down, added fluid and drove around. Didn't leak anymore. Did the tranny just get hot and had to burp? The drip was coming from where the tranny connects to the motor.

A little background info...up until about 6 months ago my 01 Ex V10 was a grocery getter for the wife; only got a few thousand miles a year for the most part. Since we moved from Washington state to Texas it has turned into my daily driver (after a 2500 mile drive towing 8k trailer).
A couple of weeks ago we were running errands and after we got home there was smoke coming from under the hood, but I couldn't pin point it. I let it be because I figure it would let me know when something was really wrong. A few days later it did it again but this time I found the problem; transmission fluid was leaking out of the bell housing onto the y-pipe. I did my research and come to find out it is most likely the front pump seal that got soft from overheating. So my buddy and I drop the transmission and replace the seal. Put it all back together and everything seems great.
Another week goes by and we have driven the Ex fairly extensively around town and even took a couple short day trips and everything is great. Then as we are turning onto an on ramp to get on the highway I give it gas to speed up and all of a sudden the RPMs climb like it dropped into neutral. I had enough momentum that I got over onto the shoulder and started to check thing under the hood. Looked like I was low on trans fluid; ok so I added a quart. Put it in "D" and still nothing. Then I try "1", "2", "R" and they all work fine.

I have a peculiar problem. When auto crossing and driving the car hard, the lug bolts on only the front driver's side wheel have a tendency to loosen. I torque the bolts to 100 ft-lbs with a torque wrench, so I am confident they are tight before I start driving. The retaining screw holding the rotor in place loosens as well. The wheel has fallen off once already while driving.
I do notice in the transition from accelerating to decelerating (only sometimes) that there is a stuttering from the front driver's side (sounds a little like an out of balance wheel). When it happens, it's often at 55MPH in 5th and at lower speeds in lower gears. The car was leaking a little trans fluid too (.5qt), but I can't tell from where. It has since stopped.

I have 2000 ford f350 7.3 diesel. (Approx 95,000 mi). Tried to tow heavy wood chipper out of soft backyard, truck on angle because of grade. Put in low and second for better traction. After somewhat high engine rpm tires started to move me ahead until spinning occurred upon which I would immediately stop and try again (slowly). Next thing I know trans fluid on ground and truck steaming. Let cool down, refilled trans oil to proper level, unhooked heavy load. Fluid NO longer leaking, drive home fine (towing nothing). What are my next steps? Very concerned I've done grave damage!?

1996 Ford F450 1 ton diesel engine truck with approximately 100,000 miles has been leaking transmission fluid. Took it to mechanic who replaced the seal and converter. When idling, you can see it drip, drip, drip, etc. Now it is leaking more than before I had it worked on.

My truck is leaking transmission fluid. I know you are going to tell me that i need new seals but, i have taken this truck to many mechanics and they assure me that its not the problem. It is leaking out the vent. There are two holes in the transfer case that we aren't sure if they are plugs but we plugged em anyway just to see what would happen and its still leaking so...not a fix. Apparently this is a rare transfer case and even rarer information to be found bcuz this model was only made for two years and because they were pretty reliable finding people that actually worked on them is even harder. Should I just buy a new transfer case or is there a way to fix this?
