Ford F-150 - 1997-2003 :: Transmission Slipping Every Time Going From First To Second Gear
Nov 4, 2012
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.

Ive got a 2001 f-150, 5.4L, 121k miles. I've replaced the fuel filter, removed and cleaned all injectors, cleaned MAF, changed 2 faulty coil packs, and installed all new plugs.
No codes thrown, truck runs smooth. Problem is intermittent. It will act as though it's got no power, usually won't happen till it's warm. I can drive it for 2 hours, runs strong. Sometimes when I pull onto a highway and get on the throttle a bit, it starts to hesitate, rpm's go to about 3k and it hesitates, but does not miss. acts like trans is slipping but I'm positive it's not.
So when it starts to do this, it's constant. I can continue to drive and it's runs terrible, does ok if you barely use any throttle. But.... I can be driving 40-50mph while it's having this problem, toss it in neutral, turn it off and restart, and all the power is back, great acceleration, as if nothing ever happened.

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.

So ever since I picked up the truck from getting the springs swapped out the tranny has started to slip more and more. It's about at the point now where it does it at the 1-2 and 2-3 gear change every time unless I give it a little throttle so it shifts harder. It's just the normal shifting pause and then the slight jerk when the next gear starts. Time to a new torque converter, or am I looking at getting my whole thing rebuilt? If it's the converter I can give that a shot myself but if I have to have it rebuilt it's going to have to wait until January or February.

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 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 new 2011 F150 4x4 6.2 liter with about 1200 miles, 6R80 6 speed Transmission. I haven't liked the shift quality since buying a little over a month ago. I think the upshift from first to second is kind of rough and it feels like it's slipping a little from second to third gear. I've read a lot of negative posts/reviews on the 6R80 transmission, and some people have said it got better over time, or it got better with more aggressive driving. I do notice it shifts better if I drive it a little harder. The build date according to the sticker is 4/11 and I don't think there are any TSB's for PCM updates for this year/engine/model. I'm wondering if I should bring the truck in now for the dealer to take a look or drive it for awhile longer to see if it gets better?

My 2005 2X4 4.6L 120,000K tranny is going out. I think I have the 4R70E and it's slipping in first gear. If i'm easy on the throttle, once it hits second, it's perfect. Tried flushing, changed plugs didn't work. I did not change the COPs. Is this the torque converter, pump or clutches? Can it be repaired?

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.

I think my E4OD in my 95 f150 is slipping in 4th gear. Just started the last couple of days, the engine rpms stay steady but the speedometer bounces around 3 to 5 mph. Thinking rebuild of the trans....

Truck is slipping in/out of gear in 3rd gear. Shut it off and the problem may not come back for several days, but in general it is getting more frequent. No codes are registering for the transmission. Curious the wisdom of performing a simple fluid/filter change vs taking it to the transmission shop. Fluid basically looks/smells good, and is full.

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 just bought a 98 f150 about a month ago from someone. The guy i bought it from said the tranny had been rebuilt about 4 months prior and i have the invoice proving it. I have lately noticed a hard shift from first to second gear, all other gears shift perfectly, but on my way from work toady the tranny seemed to slightly slip out of gear(in other words the rpms didn't shoot up, just loss of power) when accelerating from a stop light, and then it seemed to catch and started shifting ok. my question is given these symptoms is it possible that i can make this tranny last a little while longer or is it about to quit? any possible causes?

Like the title says. 04 Explorer.
No transmission issues ever. Immediately after doing an oil change myself for first time, get some transmission dropouts, slipping out of gear at stop lights, waiting way too long to go into 2nd, etc.
Then, started getting OD off light, and service engine. Error codes show something about wrong setting for 2nd, 5th, solenoid error... a bunch of 'em.
Anyway, guy at parts store says I must have knocked a wire loose causing misreads between cpu and transmission. It's a real pain getting under there since I'm using jack stands, so exactly what I should be looking for or at least the exact name of a connector or something so I can look it up.

I recently had a thread going regarding my 1999 F350 2wd auto transmission slipping in/out gear. Tried to follow up on old thread but got confused so I'm trying to start a new one. Basic problem is that truck was slipping in/out of gear. Cleaned the solenoid pack electrical plug (as instructed on previous thread) and the truck didn't act up for 2 weeks. Today it started slipping in/out again and this time it registered a code of P0705.

The Speed Needle works fine. But...the Odometer part quit some time ago. I can't tell what my fuel Mileage is now. How to troubleshoot this problem?
Things that might affect this problem; Transmission skids loudly when going in and out of 4-OD. It could be the Torque converter clutch?
The Gear shift lever is sloppy. Doesn't fill me with Confidence.
Brake fluid warning light is on most of the time. Fluid level is up hi though. Driver door mirror control switch don't work in one direction Who on this Forum has a Switch for me?

2004 V8 with 63,000 miles owned from new
When starting from cold there tends to be a hesitation, followed by what feels like car slipping into gear. Feels like past experiences with other cars having low levels of transmission fluid. In addition, display always shows PRND... rather than displaying actual gear. Related?
As I recall this is a sealed system and there is no method in any of the manuals for checking the fluid level. Correct?
My battery(ies) are likely at the end of their lives, which may be the reason for the random warning and periodic resetting of infotainment system.
Planning on putting in in two weeks to check batteries and deal with a few other things but do not want to cause any damage.

I just got my transmission replaced with a used transmission. Ever since we got it, it had been occasionally slipping on 2nd to 3rd. I thought it was most likely just adjusting to the new car as it started to get a little better, but it got worse. On the way back from McDonald's, about 3 miles, I stopped 4 times and it happened every time. It mostly only happens when it's at or below 2 rpm but it's happened once above it. The rest of the gears shift nicer than they have before and 2nd to 3rd can be the same way just not all the time. I plan on taking it back on Monday. Is there already a new problem with this transmission?

I have a 1997 F250 heavy duty 4x4 7.5 efi. I just bought a 2003 weekend worrior weighing 5800lbs dry. When I go up slight hills in 4th gear it seems to work real hard especially on freeways, could my clutch be slipping or am I just at max tow
