Ford F-150 - 1997-2003 :: 2001 - Transmission Leaks Occasionally?
Sep 3, 2015
01 F-150 7700 ed.
I have a 4R100 Tranny with 139K miles. It has been rebuilt. Ever since the rebuild (over 10 yrs ago), if I park the truck for a week or so or more, I will end up with a decent size puddle of trans fluid underneath the truck. I took it back to the shop that did the rebuild a couple times, but they could never find anything. It leaks enough to where my fluid level drops enough to cause the transmission to slip in a U-turn because the pickup tube becomes uncovered. I have a couple theories, but am wanting to hear from the collective.
Theory #1 When I park it on my slightly sloped driveway I don't regularly use the parking brake, so it rests on the gears, which eventually forces fluid out an overflow or breather tube.
Theory #2 (a very thin one) due to pressure changes associated with the weather, fluid is somehow siphoned out a breather tube due to some blockage internally in the tranny to where it's not equalizing with the outside air and has a high pressure within... ( i kinda laugh at myself for this one, but I am at a loss over the source of this)

My heater core must have sprung a leak this week. Not that I need heat in this weather but just the smell of it while running the A/C just stinks. I know I am going to have to replace it myself but just for S&G, what would a dealer charge to replace it?

Transmission lost 3rd and 4th gears so I pulled it and found the direct drum burnt up, got new drum and changed all seals, clutches, steel plates, aftermarket cooler and put a sure cure kit in it.
Truck drove great until it blew the front seal out 250 miles later, took it to a shop since I was away from home and he said the clutches got hot so he completely rebuilt it. Truck made it 150 miles and lost 3rd and 4th again. He replaced all the solenoids also.
Transmission shop rebuilt it again and it made it 80 miles and now it will not move at all. We replaced the neutral switch, shift cable, and shifter handle on the last rebuild because he thought it was hanging between neutral and drive.
What else could be making this transmission keep going out? Could it be a bad case, bad valve body or what? We are at a total loss on what keeps burning it up.

I purchased my first truck 2 weeks ago private sale a 2001 Explorer Sport Trac 4v4 4.0L. I noticed it had small leaks coming from transmission and front differential gaskets (the diff is silicone) but the oil levels remain fine. Within days I heard a loud hum coming from the engine for 10 seconds then immediately after i was slowing down for a speed bump and my truck tried to stall and since that point it was riding very rough at low speed/idle and sometimes giving it gas seemed to just kill it. Next day a check engine light comes on and I get it checked It was Bank 1 running lean and B1155 (Output shaft speed signal) which concerned me from what I found it is located by the transmission oil filter which has the leak.
A few more days later I broke down on the side of the road, the alternator had died and killed the battery, I replaced the alternator and belt, replaced the 6 spark plugs, 3 of which i removed way to easily with my hands and all 6 had an incorrect gap. Initially the car was still rough but now with the new plugs it is drivable but still a little weird on startup and idle and a little bit of the shakes around 60-65mph and seems to be over actively shifting soon as i let off the gas even a little bit. Today I had the check engine light assessed again, now Bank 1 and Bank 2 are lean, still have the B1155 as well as a new C1676 (Battery pack voltage out of range) which light research said it could be ABS module or it could be a false code from being jumped days prior and that code wont clear on its own.

The problem started with a front seal leak a few months ago which I had no choice but to continue driving with because of low funds. I don't drive much so a couple of quarts of ATF was usually enough to get me out and about for what little driving I had to do. I know.. a front seal is cheap, but I'm partially disabled and unable to work on anything that is not under the hood.
I finally scraped up enough money to hire a friend to replace the seal, but he had a life crisis before completing the work, so I had to get another friend to reinstall the trany... still had the leak, but I could get around by adding ATF as before.
So we tried again... dropped everything and put another new seal on. This stopped the leak, but we got some grinding/squealing noises and could not get the trany to engage any gear.
From reading forum posts and other sources, we decided to replace the TC which we just completed this evening. We got some more of the grinding / squealing noise like before, except that it only occurred the first time we tried cranking the engine, the 2nd time we got no noises, but again no gears engaging.
What to check/replace next assuming there is something we can look at other than a total trany rebuild or replacement. I personally find it hard to believe we could have gone from a tolerably functional trany to scrap metal just replacing a seal and the TC. Its gotta be something simple we overlooked !!

2001 Super Crew
2x2 4r70w transmission
417k miles
4.6l
Transmission shifting hard when under strain. My truck has 417k miles and the transmission is shifting a little hard when it is under strain. For example going up hills when in cruise and such forth, no problems otherwise.
My question is kinda weird: Since the fluid has never been changed or added to for that matter (fluid level is correct) , should I change it now or just ride it out? It is still my primary vehicle and runs perfectly!
I have been blessed with this truck since I bought it new
No engine work
Changed DPFE a couple of times
Cleaned throttle body a couple of times
Couple of pairs of shocks
one O2 sensor
alternator
I know its a weird question but could putting new fluid in at this time make more problems?

I Have A 2001 F 150 And I Have Just Noticed That On Cold Morning When The Temperature Is Below 35 That My Transmission Takes A While To Shift Into High. Sometime I Am Two To Three Miles Down The Road Before It Will Shift Into The Last High Gear. Is This Normal Or Should I Have This Checked Out? I Have 53,000 Miles On This Truck And Do I Need To Have The Fluil Changed An Serviced.

Question. I have never used propane to find vacuum leaks. I always use starter fluid. I understand propane is better but how nuch do you use? Low volume, or a lot of propane. I just don't want to kill myself.

I have an 1998 F150 4.6L V8 that is using coolant. I recently replaced the radiator because of a leak in the lower right side. Vehicle has about 190000 miles on it. The vehicle is using some coolant, but no apparent leaks. When I warmed up the engine after replacing the radiator, liquid dripped out of the back of the muffler - rusted out.

I have an 02 extended cab F150 and whenever it rains the rear window leaks (it doesnt have a slider, it's solid) and the half doors leak too... i sealed the back window with caulk to try and fix it and it worked for about 2 storms and then it started to leak again. The side doors leak at the seam where they meet the front doors... Should i order new seals for the windows? or is there a simpler way to do it that isnt as expensive..

I've had a 0401 code on my truck for the last two years. I've replaced the EGR valve and the dpfe sensor a couple of times, with fomoco parts. Ive also cleaned out the egr tube that comes off the exhaust manifold. In this time I also discovered a couple of vacuum leaks and replaced those. I changed the pcv valve, tried running 93 octane gas, and had a mechanic friend run a special smoke through the vacuum lines to find more leaks. Also put a brand new gas cap. I have an obd computer and cleared the code repeatedly but the light always returns.

I have a 2001 F-150 4x4 SC with a 4R70W. As a a couple weeks ago the transmission (or so I think) is slipping. When I take off from a red light the truck is shuttering. I also can be driving along at 55-60 mph and the truck jolts and shutters. I was reading some other threads and some guys think it could be a misfire, but since mine does it from a stand still i don't think it is. Just throwing that out there because it could be a factor, but once again I don't know.

So I have an oil leak I can't figure out. 2001 jetta vr6 5spd. The bottom of the car is covered with oil. It appears to be leaking above the transmission. It will consistently drip at idle. Oil sits on top of transmission and then Leaks down over the starter. It doesn't have any coolant leaks. Is there anything anything in that area that could leak oil that bad?

I have a 98 F250 Supercab XLT. 4wd with 3:73 gear ratio. twist 4wd on the dash. Truck runs great but when i switch to 4wd it makes noise and occasionally will pop out of 4wd. The noise starts at almost no speed. I can hear it at less than 5 mph. and only gets worse as i increase speed. (sounds like a bad wheel bearing) - But only in 4wd/ nice and quiet in 2wd.
I used sensors and ear phones to pinpoint the noise. It appeared to be coming from the front differential. I opened the pumpkin found clean fluid and no metal bits or any visible unusual wear. I changed the front diff. with another used unit. The noise is still there strong and unchanged. The wheel bearings and axles seem to be all right.

Ok, so I got a really wierd problem with headlights. 2001 F150, Supercrew, 4x4, 5.4L Auto lights and fog lights. Sitting with ignition off, light switch in "off" position, doors not locked - lights will occasionally blink off and on(more of a flicker). Symptoms go away if I lock with remote.
With engine running, lights "on" position. Turned lights to "park", they started to flicker, back to on, still flickering. Switched to off, still flickering. Switched to "auto", lights stayed on with no flickering.
When lights flicker, I can hear a rapid clicking under the dash somewhere(relay of some sort?). Headlight is a bit wobbly. But when I wiggle it, it has no effect on flickering. From what I remember, likely culprit is the GEM module.
Question: does a new module have to be programmed in any way or is it plug and go? I have a new headlight switch coming.

2000 F150 5.4... I was cleaning the battery posts tonight. I was leaning against the bumper when I touched the positive cable and got voltage into my knee. I have had weird electrical problems occasionally.

Have a p0401 code which I need to diagnose and solve. However, I don't believe the symptoms are indicative of the EGR system. Its a 1999 4.6L auto approximately 200k miles. Truck runs fine until it warms up, and then occasionally it begins to act like its missing under load. steady state on the freeway it may have an occasional miss, but put a load on the motor and the miss becomes real bad. This doesn't seem to me to be symptomatic of a P0401 code, but I don't really understand the EGR system enough to be sure. Searching on the forums for other p0401 codes doesn't seem to have the same symptoms.

We had my son's water pump replaced in his 97 F150. It is now occasionally jumping to completely hot. If you turn it off and back on it returns to normal. The power to the engine is cut when it shows to be overheating. The check engine light has now come on.

I purchased a 1999 F-150 Lariat 4x4 automatic transmission about a year ago. When I did, the previous owner told me about an idle issue that he has occasionally. He said that the issue was with the IAC. He claimed that he had replaced it several times but "it was hard to get a good aftermarket IAC that actually works". He said he tried several, but it never fixed the issue. That sounds like he wasn't replacing the defective part to me, but I don't know. This is my first truck to ever purchase.
Fast forward a bit (about a year), and I have had intermittent issues with idle and running rough since I bought the truck. I don't drive the truck that often, but they are becoming more common, so I want to get things fixed now.
Issues:
1. When running at idle, especially in park, the idle seems to fluctuate and never stay consistent. The idle drops as soon as I put it into drive, and the truck jerks a bit when going into drive because the idle was too high in park. It has never died while at idle, however.
2. When driving, especially up a slight or moderate hill, the power seems low and the truck starts to ping and jerk. The only way I can avoid the jerking is to stomp on the accelerator and go into a lower gear. And even when doing that, I still can notice an ever so slight jerk.
3. This past week, it was rough for an entire 40 mile journey on the interstate. Slight ping the entire ride home. When I pulled into the driveway, it was jerking until I turned it off. I haven't tried to drive it sense.
Potential issues:
1. IAC - maybe the previous owner was right. Maybe I should replace it again, or clean it with some carb cleaner.
2. Cam Phasers - I saw some posts about this on the forum.
3. EGR valve - Also saw some posts about this.
4. Maybe even the transmission? It doesn't seem to have an issue going into or out of gear, though.
