Ford 7.3L Power Stroke (1999-2003) :: 4r100 Transmission Loose After Warm Up Especially At 4th Shift Overdrive And Passing Gear
I have a 4r100 on in a 99 7.3 4x4. The shifting problem I have appears to be intermittant. it seems loose after warm up especially at the 4th shift overdrive and passing gear. possibly due to low presures ? sometimes (lately more often than not) hunts back and forth between 4th and o.d when passing or hill climbing. Under normal driving it shifts somewhat firm with 4th being an exeption.I have changed my crank position sensor filters and fluids which had turned dark and improved slightly. When I pulled the pan and replaced the filter the pan was spotless. No residue or signs of plates or debris. There is about 100,000 miles on the tranny and 350,000 on the truck. Questions: Is there a tcm for this transmission and if so could it cause these problems? I'm considering a purchase of an unlocked 1705 superchip to change the shifting but unsure if this will work for my issues...

While pullin in my 7.3 with a 4r100 from a passing hail storm, i shut her down and crawled under it just to check things out. While under there I heard a noise that sounded like something was shorting out figured out the location of the noise, but what the electrical connector is for?
passenger side next to exhaust
After further analysis the noise only happens after truck has been placed in drive gear and then to park gear and finally shut down/turn engine off... Makes noise for around 30 seconds and is not a constant short noise like something is jumping around....
More pics about the problem that is hard to get too and explain where it is...
Just behind the tranny line....
Ford Transmission :: 4R100 Shudder In Reverse Combined With A Noise
A few days ago, I was trying to back up with my 5th wheel (12,000lbs) and in reverse the transmission was shuddering combined with a noise. So I stopped and since than, the reverse is shuddering when I accelerate.
If I put it in reverse and let it in idle, everything is fine. The forward gears without problem.
Temperature always between 140 and 160, never overheated.
F350 Dually Crew cab, 7.3, 1999, 215,000 km, superchip,
Never overdone it with the power. Fluid level ok, no burned smell at the fluid, still red in color.
Ford Transmission :: 4r100 - Rattle Noise In Park And Neutral
I've got a 2001 E350 van with the 5.4 triton and 4R100 transmission in it. Has about 130,000 miles on it. I was doing some work under it a couple of days ago and noticed a rattling noise coming from the front of the bell housing. I can't hear it sitting in the vehicle or standing next to it but it's pretty scary sounding with my face under the inspection cover.
Shifting is smooth no noticeable problems there. Tranny fluid looks good, not burnt. After further investigation the noise is only present in park or neutral. In drive it goes away. In park it takes a few minutes of warm up for it to begin starting as a light tap tap, eventually working its way up to a clatter once warm. I know the 99 4r100 had some TC issues that sounded like this. It sounds like it's in front of the TC so I'm thinking the flex plate maybe?
Santa FE SM (2001-06) :: Fluid Spraying From Some High Pressure Line Under Car By Steering Rack
I own a 03' 2.7 Santa Fe (2wd) and when I got home last night i noticed that she was smoking like crazy (not overheating). Opened the hood looked under the car and noticed some fluid spraying on the the exhaust and leaking down from there which was causing the smoke. I put her on jack stands and noticed what looks like to be some hard (i think pressurized) lines that are attached to a connector of some sort in front of the steering rack. What lines are these? Power steering? oil cooler? Transmission related? The fluid that is leaking looks like transmission fluid cause its reddish brown. Ive worked on a few other cars before but not too familiar with Hyundai. When i get home later I will take a pic of this area and post a picture. And it looks like its spraying from the connecting lines (maybe a crush washer gone bad? ) not sure. I can't seem to find any image of this area online either.

Found a puddle under the X last weekend. I thought it was the pan gasket when I got under her but much to my dismay, it was not. Fluid was actually seeping from between the extension unit and the tranny. Would this just be the gasket between the two?

I've got a 03 x with the 6.8 2wd 4r100. It was flaring pretty bad for a while going into lock up, about 2 months ago the flare went away now NO lockup. Its taking more pedal to get moving and alot more slip, once you reach cruising speed tranny goes into high pressure. Told to replace the selonoid pack, got one use from a tranny shop from a tranny that lost reverse, got it home took mine out and found out the new one is not PWM and mine is, I tested my selonoid by putting 12v to pin 1 and 4 and nothing (on the pwm pack) did it to the new pack and it works. My question is what will happen if I put the non pwm in my tranny that originally had pwm pack in it?

I have a 2003 Ford Excursion with the high pressure line leaking. My guess is that the original line had a rubber hose and was replaced with a 3/8" ID high pressure hose. My problem is that I can not get the 3/8" ID replacement hose over the second larger bulge on the line going to the radiator cooler. What am I doing wrong?

My'97 Lincoln has developed a non pressure transmission fluid leak. It shows up on the street, but I measure it with the car sitting for a week and it amounted to about 2 teaspoons but the dipstick still shows "do not add". When it gets to the "add" point on the dipstick, how much transmission fluid would that be?
View 19 RepliesFord Excursion :: 4R100 Transmission Will Not Go From 2nd To 3rd
I have an 04 Excursion v10 with 170K on odometer. I am having trouble with transmission shifting into 3rd. When I take off it shifts fine to 2nd, but it will not go into 3rd as it should. I can back off throttle and re accelerate a couple of times and then it will shift fine all day long. The OD light is not blinking but I did scan for codes and there is a soft code P1741 - there is no light on dash illuminated. Just wondering if this sounds like a valve body problem or shift solenoid. I am out of town and can't ohm test solenoids til I get home.

Had my trans rebuilt in August because of a lagging reverse and loss of shift pressure. Had it rebuilt and beefed up a little and I've had problems getting the trans to be like it was new and seven years ago. I had enough of my head gasket oil leak and loosing my job recently so I bought a trans pressure kit and hooked it up today, all I can say is I now have another problem to get corrected. I'll list my pressures and I took videos so I'll upload them to YouTube and link it that way.

Ford Excursion :: 2001 - 4R100 Transmission Just Went Out
My 4R100 transmission just went out in my 2001 X with a 6.8 Triton in it. I am wondering if a transmission from a 5.4 is the same exact thing since it is more common.

I have 2001 E350 Van. One quirk.... When I put the van in Reverse, the engine drops to very low RPM and nearly stalls. This does not happen in Drive.
Transmission is out for repair now for other reasons (for a damaged pump). What can cause this near stalling? What do I look for as far as cause & repair?
Ford Transmission :: 4r100 - No Reverse After Rebuild
I rebuilt my 4r100 myself. 1st time I re-installed it, I had no 2nd gear. All other gears worked fine. Drove it less than 2 miles.. slowly..
Took it back out, found i built the Intermediate Clutch wrong. Fixed. At the same time, found a stuck valve in the accumulator VB, Fixed that, at least i think I did. all the valves snapped back under spring pressure.
Put the trans back in, Drove forward, all forward gears work. Drove 10 miles normally, w/ some time spent in all speed ranges. Temps good, outside temp was 73F
M1 = i get good engagement and engine braking
M2 = I get 1st and 2nd, seems normal
OD = Normal shifts, 4th is a little soft, but always was.. TCC lockup good
OD (Cancelled) = Normal 1-2-3, with lockup in 3rd Worked the button multiple times, shifts down, and back up normally.
N = No movement, no creeping.. Normal.. as far as I can tell.
R = No reverse, or is binding in reverse, not sure. worse when up to temp.
P = Normal, no learching or creeping.. No stalling.
The OD light never blinked, so I don't think it is electronic..
Since M1 works and holds with engine braking. L/R clutch and seals are ok. Forward clutch is ok since i have ALL forward gears, No slipping that I can tell. no creeping in Neutral, so the clutches are not fried.. New fluid is still perfect. I'll have to re-pull the pan to see if there is anything on the magnet. I think it could be some stuck valves in the VB also.
Ford Transmission :: Pump Installation - 4R100 Won't Go In All Way?
I am trying to install the pump back into my 4R100 after changing the seals in the pump. When I try to push the pump into its location in the transmission, it will not go in all the way. It is about 3/8" out too far. Shouldn't it bottom out where the paper gasket goes at the rear of the pump without torquing down the bolts? When the pump is out, if I look at the coast clutch, it is not even level with the housing where the pump should bottom out to. It sticks up about 1/16". Add that together with the part of the pump assembly that sticks out in the back and I get about 3/8" total which is how much the whole pump assembly is from bottoming out. I took out the coast clutch assembly and did not see anything binding. It felt like it bottomed out where it should. It felt like it was seated correctly.
I don't want to just torque everything down and ruin something. Is the coast clutch supposed to compress some during assembly/installation of the pump? If so, would I expect it to compress about 3/8"? Also, I can turn the input shaft freely when the pump is out. Under 'normal' circumstances, if it was put together correctly, should I still be able to turn the input shaft by hand, or is there too much resistance with all of the clutches and everything?
Dodge - Dakota :: Whistling Noise (sounds Like Air At High Pitch)
I have this whistling noise coming from the front area of my truck (97 dodge dakota) 4X4. The noise sounds like air at high pitch (just my opinion and friends), happens around 30 to 40 mph when you hear the whistling noise. I've taped all holes and gaps that might be causing the sound but no avail. I've had a friend look at it, that's a fire truck mechanic and no luck and he said it didn't sound like wheel bearing problem.

View 8 RepliesFord Transmission :: 4R100 Grinding - Now No Forward / Reverse?
A friend just bought a 99 Navigator, with what wikipedia says is the 4R100. Previous owner allegedly rebuilt the trans but used the old converter
It was apparently slipping a bit, or something, when he got it. Then on the way to my place so I can drive it and see what I think, it started making nasty grinding noises once he hit 4th gear. He got off the highway and made it to my place just fine.
Put it reverse to turn around in my driveway and it started the grinding noises again. Forward gears initially had some grinding as well after that, with no forward motion. Now there's no grinding, and the engine free revs in any forward/reverse gear
Fluid is full, still red, but smells nasty.
I don't suppose the three feed bolts above the valve body being loose would cause this? I imagine he's looking at a rebuild, which neither of us really want to do.
Ford Transmission :: 4r100 Hard Shift After Rebuild
I have a e99 7.3. had the transmission rebuilt a couple weeks ago by a local shop. have been getting some hard shifts between 2nd/3rd when lightly accelerating. Took it back already but they couldn't find anything. I am planning on taking it back again but what it is so it gets fixed right. What is causing this or what it might be? Should I be worried about having this shop try and fix this?
