Accent LC (2000-05) :: 2004 - Automatic Transmission All Of A Sudden Started Slipping While Driving
Jul 29, 2011
My 2004 Accent transmission with 145k miles all of a sudden started slipping while driving. It would be fine until i needed to slow down and then step on the gas again. It wouldn't catch right and it would slip. At first the pull of the slip was very slight and at times now it is very rough. My check engine light does not turn on when it slips slightly, but only when it has a really rough slip will it turn on. I had it checked at the local advance auto parts and i was told it has a 4th gear ratio that is off. The only thing that confuses me is that when i turn the car off and on it resets and works fine, that is until it slips again. If i drive carefully it usually wont slip. Could it be an electrical problem?? I changed my speed sensor when my car had about 132k miles because it went out, i replaced my ignition coils, new spark plugs/wires, tranny oil change, and filter change.

I have a 2001 Accent GL 1.6L Automatic.
Yesterday it started acting up on the freeway. I was driving about 50 during traffic hour when it started revving. I got off the freeway and moved to 35mph on surface streets, the revving continued at lower speeds but much worse (4-5k rpms going 10-15mpg). Doesn't seem to do it in idle or park. If i shut the car off it'll drive fine for a while then start acting up but when I was driving, after awhile, it did return to normal.
What could cause the problem? TPS? Transmission? Sensor of some sort?

I have a 2002 Accent with 119,000 miles on it. Its an automatic transmission. When I am driving the car feels like it surging forward while I have the brake on...its doesn't happen all the time. But when it does it surges for half a minute, then run fine and then surges again.

We have a '94 Honda accord that the automatic transmission started "slipping" in a week ago. It has 240K and runs good otherwise. It was sliping after it warms and seemed to slip mainly while shifting from 2nd to 3rd and 3rd to 4th while accelerating quickly. If you take it real easy on the gas it does not seem to slip much (the engine revs and the car does not seem to be accelerating, so I assume that means it's slipping - maybe not?).
I don't believe the auto trans fluid had been changed in over 100K+. The car sat for about 2 years and then I changed oil, replaced tires & battery and started using it with no probs until this (I've been using it for about a month now).
Today I changed the auto trans fluid (very dark/dirty but no real burn smell - and just a little metallic "shavings" on the magnetic drain plug), and drove the car fairly hard and heated everything up real good and it hardly slips at all now.
My questions are - with the fluid change making such a drastic improvement (at least for now), should I repeat the process and change it again? Should I try an aftermarket "miracle" additive to claims to prevent slipping? What about trying the Honda brand fluid vs. the "Autostore" brand Dexron VI that is recommended for Hondas requiring Dexron II (apparently they don't make D-II anymore)? Could it be something else - sensor, linkage, etc. (seems doubtful with the improvement with the fluid change?)?

I have an automatic gti/337 , on friday my transmission started slipping , while I would be driving on D the rpm would rev like crazy as if it was on N, I had to decelerate then accelerate in order for it to work. anyways i changed the transmission fluid and still having the same problem.
Ill be taking it to a mechanic tomorrow, but what to expect tomorrow? Its a 2002 two doors gti/337 ...

I had a 2013 Elantra that I traded in for my new Accent. The last 6 months that I had my Elantra, the transmission was slipping like crazy. Mostly when it was cold, and at lower speeds. I started noticing this while the car only had 20000 km's on it. Personally, I think it had something to do with contaminants in the fluid. I told the dealership this but they just kind of dismissed it and said it probably just had something to do with the ECU messing up the shift timing or something to that extent. They made an "adjustment" but the problem didn't go away.
It got me thinking that since an automatic transmission has so many parts, wouldn't it be fair to say that metal particles from all these newly machined pieces and edges could have some initial deterioration causing a build-up of contaminants? I think a transmission flush would've resolved the issue. That's a lot cheaper than a full tranny swap down the road while the car is still under warranty, isn't it Hyundai? It's their problem now though.

I just noticed last night that my transmission was slipping in 3rd gear, it's an automatic. I added just about a quart of transmission fluid today....took a little drive and it still seems to be having the same problem? What might be causing this besides needing to get a new/rebuilt transmission?

Just the other day I was driving my car till I've noticed the gears started slipping. At first it was having some issues shifting through the gears (automatic transmission btw). As soon as I got off the highway, I parked in a parking lot just to check underneath the hood. Everything looked fine, went to pull out of the parking lot, no reverse. The gears started to slip up really bad. I noticed that the RPM's kept on reving up and wouldn't go any faster than 20mph. I went to an advance auto parts to get automatic transmission fluid. Still having the same issue and no reverse either. I had to park the car at a location to get it towed back to my house. Some people are saying my transmission is bad, some say it could be a real simple fix. Where to start diagnosing this issue. The car was driving normally until last Monday. My question is where should I start to check and what can I do to see if the transmission is completely shot??

I have an 04 2.7 litre V6 AWD Santa Fe with 189235 KM , with a Shiftronic transmission, recently, while in "d", the transmission would feel like its slipping or perhaps trying to down shift, its hard to tell what it's doing really, but if you then slapped it over into shiftronic, it would operate fine, no slipping, locks into gear strongly, indicating that its not mechanical, but related to the computer controlling "drive" function of the transmission, I flushed the transmission just after the symptoms arrived (using the correct SP3 fluid) and this made no difference, the old fluid, although ready to be changed, was not burnt or blackend. I thought of getting it reflashed ( read it online) but I am not sure it will work, especially if its like a sensor or something.

So I bought a 2000 Hyundai Accent for my 16 year old daughter and the guy sold me a car that has a slipping trans. So I went to the Autozone and had the codes pulled and it was a P0734 code. I replaced the trans fluid and replaced the internal bearing and shim with the 42220LK kit from whatever it takes transmission parts store. Trans still slips. What else or should I just unload it?

Sot he automatic transmission has never downshifted correctly for me in my "01 Hyundai Accent 1.6. I am on my second tranny, but they both never downshifted properly. For it to do so, you have to come to a complete stop for it to get back to first gear. If not it kind of bangs into first. Either that or it will dog out in third once you hit the gas, but will go into first. With my first transmission, I replaced the fluid and filter and it still did it. This second transmission has about 60k miles on it with new fluid/filter and does it.

2000 Hyundai Accent GS, 1.5l, 4cyl SOHC...
I have a slight issue. A few weeks ago, I put some "STP" style fuel injector cleaner into my gas tank. Either A) It cleaned everything really well and clogged my injectors, or it turned into gunk and possibly clogged something else up.
Ever since that day, my issue is that the car "stutters" very slightly. When idling, it'll "hiccup." When I'm doing normal driving, 55-60mph at 2k RPM, It'll almost feel like a transmission slip.
I've went and replaced my Fuel pump, filter, and now I've done half a can of seafoam through the brake line power booster (vaccuum) straight into the engine, and the other half into my oil for further cleaning. I also applied Seafoam Deep Creep into my throttle body, just for further maintenance.
Ever since then, everything has been running noticeably better, and I've had a huge increase in gas mileage, but there's still a slight hiccup that occurs during idle and driving.
I change the oil /filter, plugs, wires, air filter on a regular basis.
I also had to change the MAF at one point in time, as it died and the car wouldn't start at all.
Next thing I'm thinking about doing is changing the plugs / wires one more time (it's been about 5 months since my last change) just to see if I bought a faulty plug.
The car was put on a computer and the only error code that came up was one about my check engine light being out.

I have a 2000 mercury cougar 2.5 liter. I bought the car without doing much research. now that i have the car did research and found out all the great problems that this car has. My transmission started to make a clunk clunk noise inside and it started to slip. At first it would go on all gears. then very rapidly started to slip in all gears. In matter of hours went from being good to being crap. i had to accelerate the car to 3000rpm or higher to make the car start moving. So i bought a transmission from a junkyard. I install it and did not work. The car did not move on any direction. I pull it out and look at it and found the small shaft that goes from the torque converter to the gear body was broken. I end up getting another transmission from the junkyard. I check it and everything looked good. I install it and got everything back together and that work on reverse but no forward. To get it on reverse I had to accelerate the car to 3000rpm. I being told that if I change the solenoid inside the transmission might fix the problem. It could be the transmission module that is burned out.

Owning a Hyundai. I have a problem and it seems to be pretty common but haven't gotten anywhere with it yet. Last week my 2004 accent 1.6 manual transmission started running rough. It was idling higher than normal and while driving would not go past a certain rpm (about 2500 if I had to guess,no tach). On the way home from work it was running this way and then started badly misfiring and shut off, when attempted to restart it would not. I pulled the codes with a scanner and got p2400, p0562, and p0121. I charged the battery and replaced the throttle position sensor, still won't start. I can hear the fuel pump kicking on when I turn on the ignition. Also found the ecu 1 fuse blown, replaced it and continued to attempt to start with no luck, fuse was blown again. Like I said I haven't owned the car long and I don't know much about it. I am not sure where to go from here and I don't know how all these symptoms are tied together.

My 87 Acura Legend with 210,00 miles has an automatic transmission slipping problem. Car will not start moving when in the D position (slips), but if i shift manually to 2 , then S3 , it shifts ok except for some shuttering when shifting to D at about 35 mph. It also does not lock into Park when shifting to P position( car will roll when on a hill.) The shift cable and adjustment are ok. The S3 light does not blink and there are no codes stored. The trans fluid was changed 5,000 miles ago and level and condition are both good.( I have only used Honda fluid for the life of the car and change it every other oil change.) I removed the shift solenoids to find all of the screens clean and all solenoids clicked when 12v applied. At this point i realize i probably have an internal problem (possibly bad clutch pack?) My question is why doesn't the parking pin lock? Is this related to the slipping problem?

My 2009 Santa-Fe AWD Limited is sick! Starting from a stop, the vehicle has abrupt shifts with the transmission slipping (RPM revving). Seems worse when cold. Checked the fluids, and found ATF fluid in the engine oil and engine oil in the ATF fluid. Quick internet check suggest a leaky vacuum modulator valve. (There is no way the fluids went in the wrong holes, the vehicle only has 69k kilometers on it, so it still has original ATF fluid, and I recently changed the engine oil myself.) So, do you think this is the correct diagnosis? How hard is it to change the modulator, and where is it located?

I have a 2002 1.8T tiptronic with around 150k Kms. Recently, the transmission has started slipping, more so when at running temperature than when cold. It feels like when a certain amount of gas is applied is when it starts slipping. It can slip immediately after 3-4 and 4-5 with continued acceleration, or will constantly slip while in 5th if trying to drive at speeds greater than 90 km/h (with very gradual acceleration to that point).
Does this sound like a clutch wear issue requiring a new transmission, or more like a valve body issue?

When the car is cold it runs fine. After driving for 10-15 minutes the transmission slips, while driving the engine revs and then engages again.I have only noticed the disengaging/engaging as speeds less than 40 MPH. When the car is in neutral and placed into drive it may take several seconds to engage which happens about 60% of the time. Could this be a sensor failure or time for a new transmission?

I own a 06 sonata with 95000 miles. Recently I've been having issues with my transmission. It occurs only at slow speed when i travel in first gear. What happens is when the car is moving, it feels like it shifts into neutral but indicator still shows D in the cluster. I press the accelerator nothing happens it just revs,no increase in speed whatsoever.
So that rules out slipping issues. Now i narrowed the problem down a little more whenever the problem crops up i shift the gear lever into sports mode, i feel a jerk and car shifts into first gear and it moves. If i dont shift into sports mode it catches gear in about 7 seconds.No fault codes.
And if i rev it high transmission goes into limp mode and stays in 3rd gear till i restart the car.Then i get P0731 incorrect first ratio.Changed ATF 7000 miles ago. Could it be a faulty range sensor?
