Ford F-150 - 1997-2003 :: 1999 - Torque Converter Vibrates - Engine Misfiring?
Jul 29, 2010
I have a '99 F150 w/ the 5.4 and 4R70W, with 226K miles. I am experiencing what I believe is a TC shudder after the tranny shifts into OD between approximately 40-50mph. This sounds like a pretty common problem with this particular tranny, but some of what I've read describes the shudder as feeling akin to driving over rumblestrips, but what I'm experiencing is a very sharp, bucking. Is this how the TC shudder feels, or am I actually dealing with a misfire. Btw, I did completely change the tranny fluid with Mercon V, and added a friction modifier, but no change. I also read that the TC unlocks when the brake lights come on, so I tried lightly hitting the brakes when the bucking was occuring, but it continued.

I highjacked another thread yesterday but didn't get many responses so I thought I would start a new one... I've done some searching here but no one had any real answers or had a different reason for the vibration...
We have a stock '05 F150 with 24k mi that is having Vibrations not related to bad tires or a bad trailer. It rattles any cups or change that is in the center console area and the dashboard. It seems to come up through the floor.
Symptoms timeline:
The rear pops when you turn tight in a parking lot. I've been told this is normal because of the ratcheting LSD? Is this true?
The tranny fluid was low and we could not find where it was going. Put several qts in it and finally took it to the dealer where they replaced the bad seal between the transmission and transfer case. So we know they took the driveshaft out and the transfer case. Not sure if they dropped the transmission out.
We have a vibration from about 40mph-55mph under medium-full throttle. A lot worse when towing. Put it in neutral and it goes away. Rev the motor and you don't feel it. Only happens under load. Happens in 3 and 4th gear. Goes away once the torque converter locks up.
Am I going down the right path in saying it's a bad torque converter?

I have a 97 F-150 Supercab XLT, 4X4, 4.6L W, 4r70W with electronic Overdrive, manual shift transfer case. I need to remove and replace the Torque Converter. My question is: Would it be easier to drop the transmission and transfer case or pull the engine loose and move it forward to get at the torque converter?
It is shifting in and out of overdrive to third, and then back into OD, and back into third erratically and for no apparent reason. It is also slipping intermittently in first from a dead stop and locking all at once, shifts hard then. When I first drive it the OD light does not flash and the OD off switch works, once it warms up good it starts shifting erratically and the OD off switch starts flashing, then the off switch does not work.
I did not get any codes returned on autozones little scanner and am taking it to the ford dealer for a full scan today to see if there might be any other damage or cause for this problem. The problems started when I blew a hose to the trans cooler in the radiator and lost fluid. I didn't notice the blown hose until it started slipping and pulled over, replaced the hose and fluid. Had problems ever since. I have cleaned the MAF sensor and replaced the ABS sensor in the differential so far.

I have a 2002 SuperCrew 4x4 that makes a squealing sound that starts at 3000 rpm and slowly goes away as it approaches 4000 rpm. It does this when you are in park or in gear. I believe the torque converter is going bad, but just want to make sure before I tear it all down.

So my transmission drove perfectly fine I just wanted to put an upgraded torque converter in especially after driving a customers' truck with a low stall converter. I know their not like for racing or anything but it's a work Truck with some mods to the motor nothing crazy. So I went ahead and bought a low stall triple disk converter and I drove around the block fine and went to go on the freeway and got into fourth but lost it as I hit 75 (was not flooring by any means and had it in the stock tune) now it will not go past second gear. Once it did this the o/d off light started to flash and I decided to do a stall test.went to 1800 in a Second. Suppose to stall around 1200-1300.

1999 7.3/4r100 4wd with the rattling torque converter.
I bought this truck 10-11 years ago to use as a tow rig for my landscaping company. It has been a great problem free truck, I have done brakes a few times, a water pump, ball joints but no issues with motor/drivetrain.
I don't know the history of the trans before I purchased. Ford didn't have history of it being replaced and even now it still has all the labeling on the case. I would have thought it would have been washed off in a rebuild. Again I don't know. When I bought the truck it shifted nice and crisp, having owned trucks before it made me think it had been rebuilt but this was my first and only 4r100. Other trucks are ZF6 manuals.
Anyway 10 years and 100,000 miles later it still shifts very crisp and fluid, has been changed a couple times, is nice and cherry red. I added a 6.0 cooler, temp gauge and filter. Never see the temp rise and haven't seen much in the filter.
About 25,000 miles ago the TC started to rattle, a known 99 problem. I figured surely the trans would go and I would do a rebuilt from Ford. It keeps going though so being a work truck I have kept running it.
A couple weeks ago the starter just spun and wouldn't engage. I pulled the inspection cover and noticed some missing teeth on flex plate. Got it to start my turning crank bolt a bit to good teeth and the starter caught. Now we are carrying a breaker bar and socket. It has happened a few more times so I need to replace flex plate.
Question is, since I need to pull trans to replace flexplate, should I replace TC (I would like to get rid of the noise)? Some people have said I will be replacing trans in a couple months if I mess with it. They say just spend $3000 on a rebuilt now with a converter. Not trying to be cheap but hate to just dump this trans that is still working great and has served me well.
I have replaced many transmission and done clutches in many trucks so I am familiar with the steps of removal and installation, just stuck on what I should do.

I have just finished changing head gasket. I started up the engine works fine. But I hear a little clik sound form the converter. I put it in gear, but it can't move either forward or backward. It ran 2-3 liters of oil out of the converter when I took the engine out. I have filled new oil in the gearbox but not in the converter, dosnt it came form the gearbox into the converter?Is there air in the converter or what's wrong?
it is a F150 4x4 4.6 1997 automatic.

This car has been giving me quite a bit of trouble lately. 04 Ford Taurus SES, about 97,000 miles on it. Just last weekend, it broke down on the highway. Found out the torque converter failed and needed to be replaced. I was suspecting that something was wrong with the transmission for a while now, because it would stutter sometimes when accelerating, and sometimes start shaking in the front when I turned it on. (It still stutters after having the torque converter replaced.)
Well now, a day after shelling out quite a bit of money to the dealer for this torque converter, the check engine light is on. I went to Autozone to check the codes, and they found P0300, P0305 (cylinder misfire) and P0316 ("crank sensor condition"). Is it possible the transmission is failing?? I found a bunch of complaints online about the transmission failing on the 04 Taurus. I'm trying to avoid more expensive repairs, but I don't want the car to break down on me again....
Also, a couple months ago, the check engine light went on a few times, but always went off within a day or two. Never did get it checked out because it didn't stay on long enough.

I have a bone stock (other than exhaust) F-250 SD, 6.0 auto, 185k miles. I have a substantial vibration when the torque converter locks - about 50-55 mph. Once the transmission warms up (i.e. 4-5 miles from a cold start) the vibration goes away and the transmission performs flawlessly. Backing out of the throttle and allowing the TC to unlock makes the vibration go away, as does shifting into neutral. There is no noise, just a vibration that will shake the whole truck. Transmission fluid looks good, and showing full. Have had the truck about 4 months, and have not flushed or replaced the filters on transmission.
I've seen a couple of similar threads on vibrations, but not one where the vibration will completely go away. I'm thinking replace the torque converter but wanted to get more information from the experienced experts that know these 5R110s better.

When running up through the gears under normal acceleration I can feel almost a double shift in 5th gear. It doesn't occur using tow/haul so I assume it is the TC locking up. Everything else seems fine. Truck has 9k miles, mostly towing. 2016 6.2 ....

What the torque spec is for the driveshaft to rear differential flange mounting bolts on the 99 F150 4x4 supercab?

Tell me the torque specs for the various attaching nuts of the front hub assembly for the 99 F150 4x4 5.4L (large nut on the spindle, mounting bolts to back of spindle, etc if any) ? I will need them to put everything back together after checking the tone ring for my ABS problem.

I have an issue to where every once in a while my truck will not shift and when it does shift it slams into gear, and my overdrive light flashes and then I'll turn the truck off let it sit and crank it back up and it drives fine and the overdrive light is off. It shifts normal and smooth other than when this happens. Not sure if it is my torque converter or maybe a solenoid or what. My truck is an 07 f250 6.0 with 192,000.

I recently purchased this truck so I don't have any history on it. It's the V10 motor, automatic, 4 wheel drive, with a crew cab. I took it to Advance Auto to have them read codes and it came back with torque converter solenoid fault and 2 other codes related to that part. I didn't get to see the actual code numbers.
I've talked to 2 transmission shops and they said they could throw a solenoid pack into it, but that it might not even fix it. The truck drives fine, shifts fine, the tranny oil looks and smells fine, so I'm tempted to not worry about it until something else happens.
The truck has 217,000 miles on it...

I have a 2002 7.3 with the 4r100 173k miles. If your nice to it she drives fine, but if you get on it the torque converter will slip/stall kinda revs up like 300 rpm then slams really hard between 1st and 2nd. Other gears work fine. I've only had it not happen like 10 times since I've owned the truck ..... I don't really beat on it except for towing which I'm starting to do a lot of. Wondering if putting a new stock torque converter in it is worth it.? Not gona blow the bank on a TC unless I'm putting a brand new trans in the truck. Which I don't think it needs in the near future.

2003 F150 5.4L Tow Package 140k miles... Had coils, all plugs/wires replaced two years ago due to vibe climbing hills. Now at startup in the morning for a minute or two during idle, the engine vibrates severely then subsides and runs fine rest of day. Doesn't do this every morning. Truck lives in FL. The issue is either temperature related or moisture related. Ford service has the truck presently and attempting to diagnose from an overnight stay. They already 'fixed' the problem last week by replacing #1 plug/wire and resetting the power control module (pcm) but two days later the problem came back. Tech said today that the plugs currently installed are Bosch (any issue with these plugs?)

I have a 99 f150 with 171xxx miles and the other day it suck in second gear and start shaking and misfiring and would stall out. I took the truck and got the codes read and it threw codes for the tcc solenoid and shift solenoid. I put both in the transmission and it kepy doing the same thing. I check fuse 24 under the hood and it was blown, I replaced it and everything worked fine for a day then it blew the fuse 2 more times and i cant figure out why it is blowing that fuse. I cant find any shorts maybe pcm??

The SES light in my 2001 7.3 came on about a month ago while I was towing a light trailer in the SoCal mountains. When I got home I spent about 2 weeks replacing the injector o-rings and glow plugs. I discovered while I was in there that the head bolts on the driver's side where loose. I retorqued them to spec.
Both batteries were disconnected for the 2 weeks. When I started the truck the SES light was still on.
My Torque Pro app isn't showing any error codes, and is reading live data correctly. (I didn't have the app when the light first came on; I only purchased it after I finished the repairs). Am I missing something? Is the SES light not necessarily connected to fault codes? If so, wouldn't it reset after 2 weeks with the batteries disconnected?

So here I am driving away for the fuel station and then the tranny tries to shift and I hear and feel a loud clunk followed by no power. I have had no previous issues with the tranny but I believe it has not had any previous work done. The truck is an 02 7.3L with 200500 miles. I am guessing the torque converter is the culprit it still had very little forward motion when I tried to move the truck didn't matter what gear I was in. I intend to have the tranny beefed up but don't intend to go crazy. I do tow an 11,000 lbs TT on a fairly regular basis and have a PHP 6 position switch which can be set for as much as 120 hp from stock but don't do any hot rodding. I am mostly just looking to beef it up and provide as much strength towing.
