Ford F-150 - 1997-2003 :: 1999 - Transmission Stuck In High Gear And Bogs The Motor Down
Nov 17, 2012
I have a 99 F150 4x4 with the 4.6 Motor approx 150000miles. Transmission went out so I decided to try and replace it...
New/rebuilt tranny went in with no problem but something is not right. It will drive but seems like it is stuck in high gear and bogs the motor down. It is giving me error codes P1747, P0750, P0755, P0743, P0102. All the wiring harness is in good shape with no burns or other noticeable problems. Somehow the transmission isn't reading right?
When I bought this rebuilt transmission I was told it was set up for 2wd but he would convert it for 4wd. The only difference i noticed with the new tranny is the shaft coming out of the tranny, where the safety neutral switch is, has a diamond shape instead of the oval shape that connects the shifter cable. No big deal i think, just had to buy a new link for the shifter cable with the diamond.
Also on the passenger side of the tranny there is a nine pin plug. My wire harness from the truck has one pin hole that is opposite of the tranny. Not sure why. Do I need a new harness or wrong tranny?

I have just put in another transmission and the truck will not shift out of first gear, it will go in reverse and first and reverse. The guy who had it before me had the same problem when he put in a transmission with only about 40-60,000 miles he assumed it was a bad transmission. And that's how I ended up with the truck. We have so far installed yet another transmission and it is doing the same not shifting out of first that it did for him. There is no cel or blinking overdrive lights, checked fluid levels, checked selinoids, gonna purchase a used computer for diagnostics, I am stumped with limited knowledge. The dealership said the transmission should be the e40d I'm reading it should have the 4r100 is that correct? The truck is the 5.4L v8 with 74,000 original miles. Truck sounds amazing. I really want to fix it.

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??

This morning I went to go to work, started to back out of the drive, and the transmission locked up. So I go to put it in first gear, let off the clutch, and the engine bogs down like its in 5th gear. I then decided I will just push it back in the drive, so I put it in neutral, let off the clutch, and its still in a gear while in neutral. Last night it drove fine before parking it, and then when waking up its broke. What could be wrong?

I have a '97 F150 Lariat Ext cab, 5.4, 2Wd, 175K, a bit rusty but for the most part functional. Unit is parked for long periods of time.
3 - 4 years back the gear shift did not want to go into PARK and and the gear indicator was out of register. Unit would not start and I had to move shift lever to N to start. Fixed the two screws on shift plate/column per this site. Then 18 months ago same thing begin to occur but this time I used blue thread lock to hold screws in place. Still had to throw into park to get it to stay.
6 months ago shifter became very difficult to move and near impossible to get into PARK. When in PARK the interlock must have not been engaged so had to move to N or push lever hard into PARK to start.
Tired of this so I cruised the site and found several posts on taking dash apart, repairing a broken shift tube and or replacing bushings.
Battery disconnected, dash apart, cluster out, steering wheel still on and steering column still in position. Shift tube appears OK, i.e. not broken as in one post, bushings appears OK as there is no play or slop evident, but I cannot get the shift lever to move from PARK, period.
When the shift lever is pulled toward the wheel, a pawl on the tube causes a plastic or nylon arm to move about 90 degrees. It must be a stop or safety of some sort. I have not dug deep enough to see the shift plate with the two screws. At 75 I find it difficult to lay upside down to reach and hope I can get to them from the top.
Questions:
1. How do I get it out of PARK to check all things on shift tube and gear selector units?
2. Does the battery need to be connected for the interlocks to function?
3. Do I need to drop the column to check on shift tube items?
4. With a rusty trans, can the shift cable to trans connection be the problem?
5. What to look for, how to repair. etc.

I have a 97 250 LD 5.4 that suddenly has a grinding noise coming from the area where the transmission and motor meet. I took the inspection plate off the transmission and can look up inside there and see everything moving. I use a screw driver and if I flex the plate that mounts between the transmission and the motor I am able to get the noise to quiet down until I release the screwdriver and then the plate flexes back and scrapes making the noise again.
I can not see where the plate is grinding when I look up inside there. I can't figure out how to fix this.... Why it would just start doing this on its own as none of the bolts on the housing have been removed except for the two bolts that hold the starter on. (Changed it a couple of weeks ago). Thought about loosening the bolts on the tranny housing but I'm afraid that it would open me up to further problems???

I've had my 03 VR6 6-speed for 12 years. It's been a second car for the last 5 or so, but regularly used. Friday morning the car got stuck in 3rd gear. The stick will only move from neutral position and down towards 4th gear. I've inspected the short shifter under the hood and the bushings under the shift boot. I did not find anything that diesel geek (the short shifter company) had me check for.
I brought the car into a local shop I have never used before (my usual shop closed), and today they called me saying its a transmission issue. I have not given them permission to open anything up. I am going to take the car home for now.
I have had to repair a broken 1-2 gear fork before. And at that time I had the 3-4 gear for replaced as well.
I should also mention, I similar issues on a quick drive i took the car on the night before. I thought it was just me acclimating to the shifter/lower power of the car as I hadn't driven it for a while. The point is, it drove fine afterwards and it drove fine for a 40 minute city drive to work the next morning.

What is the testing procedures for the blower motor controller on my 2009 150 Lariat. In the old days it was called the resistor but now it is computer controlled for the dual climate control. My fan is stuck on high, the fan switch does work(the bars on the display change when I push the fan speed button). The climate control works also, just blasts you with air and the temp is changing a lot due to the fact of the fan on High. I am 99% sure it is the blower motor controller, but I would like to test the controller.

I don't know if its a coincidence but it rained hard all weekend and went to work this morning to find out the blower motor only on 4(high). I checked the plug going into blower motor and it looks dry and clean. is there a common occurrence with this? What to look for?

I have a 1999 Explorer. 5.0 V8 auto AWD. Motor bogs down when going up hill. Smoke coming from under vehicle. Recently tuned up & oil change. 157,000 miles. No warning lights. Not over heating. No burnt smell from oil or trans fluid. No leaks from motor or trans. Oil & trans fluid look clean. I have a little mechanical knowledge. Someone said it could possibly be a bad catalytic converter.

I just came back from a long trip and during the 400 miles drive I started to hear noise coming from my differential - kind of like a constant high gear loud noise. I will hear this noise when I start to accelerate and it will only gets louder and louder as I go faster and faster. I had a pinion seal leaked fixed last week and I checked the fluid and it is full.

2002 F-150 4.2L. About a year ago, it threw the P0171 and 0174 codes up. After replacing all the simple stuff, I bit the bullet and replaced the lower intake gasket as well as the upper intake gaskets. Buttoned it all up, reset the codes and we were back in business. No issues, truck ran good. About 6-8 months later, the check engine light came back on, I check it and it was that pesky set of codes again, 0171 and 0174.
It still ran fine, but the codes were there, so I just drove it for a while (it's a company truck that doesn't get driven that much).
A couple of weeks ago while driving it, it acted very sluggish. You could mash the accelerator and it would just very slowly run up the speed. It never hesitated or missed, it just got very very sluggish. Checked the codes, no additional codes.
Then it began to stumble when you mashed the gas.
I put new plugs (old one's looked great, other than a huge gap), new wires, new coil pack and started it. Pushed the gas pedal, it just dies.
I look for obvious vacuum leaks and replace a couple of elbows for the PCV and it seems to run a little better. Enough so that I can drive it, but still not running right.
I ordered all the intake gaskets and new isolator bolts and spend Saturday pulling that apart. I didn't do the lower intake because the upper intake gaskets looked so good, I just don't believe this is a intake gasket problem. None the less, I installed the new gaskets on the plenum and upper intake, new isolator bolts, replaced a couple pieces of vacuum hose that looked cracked, started it back up, it ran as smooth as silk.
Convinced I had it fixed, I went for a test drive. Idling, it is as smooth as you could ask for. Pull up to a stop sign, wait, step on the gas and it chokes. Just stumbles and you can hear it almost backfiring and pushing air back through the system.
I've put new PCV, new EGR, new vacuum lines in several places, new upper intake gaskets, new plenum gaskets, new isolator bolts, and even new o-rings on the injectors, and I'm still getting the 0171 and 0174 codes.
With the diagnostics on, I can see voltage varying on all O2 sensors, so I assume they are working (none of them are reading 0 volts). It doesn't throw any other code up, other than the 0171 and 0174.
At this point I feel like I'm replaced every single thing ever mentioned in any 0171 and 0174 thread on the internet. Where to go next? 1 more point, if you very slowly push the gas, it runs fine, but any pressure on it, it bogs down and just stumbles.

Woke up this morning and was going to work. Went to unlock my truck and noticed the lights didn't come on inside when I used the remote door unlock. Then I started truck and the tranny lever on the steering column wouldn't go into gear plus the sterring wheel will not lock when the truck is off!

I have a ford f150 supercab XLT with the 4.6L triton. It starts and idles absolutely fine but when i push the gas to fast(when in park) it bogs down. I just changed the fuel filter aslo...No change.
If I floor it it Bogs then goes up to about 3000rpm (about halfway) and has trouble moving over that RPM or halfway. like theres a restriction of some sort.
If I gradually push the gas, it will go up in rpms and i can get it to about 2000 rpms then I can tack the rpm gauge out if I wanted. but never do.
Also when driving, it seems as if its lacking power..and just to add it does all this stuff while in gear also..
When running It smells of an exhaust leak. but I cant find one. And I cant smell it in the cab.
So there it is. If I think of anything else, or do anything. I will keep posting.

I have a '97 F150 4x4 with the 5.4L engine and automatic transmission. The tranny's been slipping on and off for a couple of years. It started when it was hot outside, I had been driving a long ways, and I was trompin' on the gas to pass someone. Still, the slips were rare. As it got worse during the hot summer months, I just minimized my long-distance travels.
I recently took it to a transmission mechanic. Like some of the feedback to posts in here, he felt it was a problem with the engine - because we had a bad EGR valve signal on the computer. (We still flushed the fluid. I later replaced the EGR and the DPFE. Another mechanic went through everything, replaced some valves that had something to do with the EGR, and feels the engine is 100% (and it runs very, very smooth). For those that will bring it up - I have replaced all of the coils (though it's been a few years). Having actually replaced some numerous times over the years, I can feel when one is bad (of course, the 'check engine' light as well). Lastly, we've replaced all bulbs in the dash so they are all working as well. Also, the transmission is not leaking. The computer system is giving us no errors/throwing codes.
After a couple of weeks, I happened to drive the truck a long distance one day and it started slipping. It got bad enough that it was slipping every time going from first to second gear. It would usually engage as I took my foot off the gas. Since then, because I haven't driven long distances, I have not had a problem.
The transmission mechanic thinks it's still an engine issue. He also mentioned a mechanical/electrical switch system on the side of the transmission (?). Give me a list of things to look at.

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 !!

I have a 1997 F-150, 2 wheel drive, 4.6L truck. Recently the transmission got to where it didn't shift properly. Then it got to where, after driving it about 10 to 15 miles the transmission would drop out of gear with the transmission selector in drive.
I have replaced the transmission sensor, the rear end sensor and it still does the same thing. Drive about 10 to 15 miles and, with the transmission selector in drive the truck will not pull. The motor can be rev'ed but the truck won't move just like it was in neutral.
What is wrong. The transmission shifts fine, the truck runs fine, but after 10 to 15 miles the transmission quits working.

I have a M5OD that I replaced the clutch in in my '99 150 4wd in December . Manual Tranny. Now when taking off in 1st gear the transmission seems to be sliding or shifting backwards, but only in first gear. Got under my truck and looked, can't find any identifying marks to where it might be moving or what is causing this. All frame mounts are tight and the bell housing is flush with the motor. Yes, i did do the clutch change myself in shop class.

We currently have a 2003 Honda odyssey with about 119K miles. About once a month the transmission does not want to change between 2nd and 3rd gear causing it to rev very high. The only resolution is take your foot off the gas until its back to an idle state. Now I have read that these transmissions suck and have a bunch of problems. We are driving long this summer and we need a new trans. Last year when we drove to NC the car started to buck and rev really high when on cruise control for awhile. not sure if its connected but it was not fun.

When I "step on it" on the freeway or even a moderately inclined freeway ramp, it bogs down and actually takes a few moments to cover. Sometimes will leave me crawling at about 20mph for a few minutes. Engine revs just fine in neutral. If I very slowly build up speed I can cruise at 75mph, but forget passing. Also, this came along at the same time a severe shaking/shuddering spell started. Not always, but often it is shaking the entire body and certainly through the steering wheel. Was so bad the first time I stopped to see if I had a flat. Usually lasts until I slow way down and ease my speed back up. Had the front end steering structure replaced about two years ago, so I don't think it is that. What is the cause of the bog down and could the shaking be related? This truck sits for 2-3 weeks at a time and then I drive for about 50 miles and park it again. Can Michigan gasoline go bad that quickly?
