Santa FE SM (2001-06) :: 2004 Automatic Transmission Feel Like Slipping Or Trying To Downshift
Sep 7, 2014
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.

Recently started experiencing a hard downshift after driving for 30 minutes, and only from 2nd to 1st. No other shift issues with other gears, up or down.
When moving over to manual shifting, it doesn't appear to have the issue when downshifting in manual.
I replaced the radiator about 2 weeks ago due to a serious leak, and the shifting problem wasn't an issue before as I would have noticed.
Going to start with the fluid lvl, but it feels odds with it occurring during the downshift to 1st.

I just recently bought an 06 Santa Fe with a 2.7l v6. It was a rebuild. It had been hit in the left wheel. The lot put a new fender, suspension parts, axle, etc. It only has 25k actual miles.
We took it on a 100 mile trip today. I noticed if I am going up hill and it has to downshift, it feels like it looses power. The car continues to slow... Like the tranny is slipping. I stopped at Walmart and found the tranny fluid wouldn't even register on the dipstick. I bought Valvoline max life tranny fluid that matches the sp3 specs in the manual. I had to add almost 3 quarts before it was full. I think they may have forgot to add fluid back to replace what leaked out after they replaced the axle It didn't seem to work though when I continued to drive. After I stopped and let it cool about 30 minutes, it did seem a little better.
I guess my question is should I replace the tranny fluid? If so, what should I replace it with? Is there anything else what could be causing this now?

2004 2.4L suv with 98K + miles. Transmission was slipping periodically - fluid levels were fine. Someone suggested changing fluids as it may be contaminated. This car has a manual option also that I don't normally use but I did take car out on a longer drive and it shifted as I directed. Since car is almost out of warranty (naturally) I was trying to find answers as I don't feel dealership will be honest with me. While I have not had an actual slip (engine revving and not moving) since fluids changed 2 weeks ago it does seem slow to shift. Since it was not consistent someone said the sensor may be going.

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?

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.

So the problem is that I have a jerky downshift 3-2 and 2-1 that can be felt by everyone in the car (car pushes forward on downshift) until the car warms up. When the car is warm I can feel it slightly at times and feel a clunk when shifting down 3-2 and 2-1. On up-shifts at times the shifts are shaky from 1-2 and 2-3. I have brought this forward to my dealership as well as another one. They all performed software updates and reset the adaptive learning. However every time I got my vehicle back after this procedure I found the A/C was on full blast. So the initial drive by the tech after the reset was learning while the A/C was on. Would this be causing the weird shifting I experience while the A/C is off. I seem to notice a better shifting when the A/C is on but this may just be me trying to reason why my transmission is behaving this way. I drove other 2015 Sonata's and they have much better shifting than my car and no hard jerks on downshifts.
Both dealers have felt the downshifts and have come back and simply said "We've done all the updates and reset and learning. This may just be a normal characteristic of the car." I told them that a brand new vehicle in this day and age shouldn't be shifting poorly when compared to an older vehicle with 300,000 km (my old Honda Civic which are prone to transmission failures). They responded casually saying you can go and get a second opinion from another dealership if you like. I am furious with their responses and just left it at that. I need to know how to get this resolved and if this is indeed something I should expect from my Sonata.

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?

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.

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 ...

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?

I have an 06 sonata 4 cyl automatic.Today the transmission was slipping in first gear like the car was revving in neutral.Then after restarting the car it was completely normal. Code P0731 showed up.

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?

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?

I have been noticing that not only can I feel the trans. shifting but it feels like an old trans that is slipping. Is this normal?

We have a 2010 Santa Fe AWD LTD with about 140, 000km on it. It recently came back from front suspension work. The suspension is fine now, but we notice harder shifts in the transmission. Also, there seems to be a vibration just before shifting gears and when under load (like going up hill) seems to slip (like on ice) about once every second until the shift is made. Once the shift is made it drive smoothly until put under pressure again. Even stepping down a bit on the accelerator will cause this slipping feeling (or maybe its loss of power).

I have a 2001 Accent with a 1.6. This car is mostly driven by my daughter so I'm translating the symptoms as she has described them to me. The issue appears to be this - when driving at highway speeds the car will sometimes downshift from OD to 3rd gear and stay there. When the problem first started, she would pull off the highway, turn off the car and then restart it - this would appear to "fix" things temporarily, however, as time went on, it would work up to (and including) 3rd gear and not go into OD after a restart.
I've reviewed the various threads on this site describing the 4th gear problem prevalent in the Accent, but in each case that was posted, there was a check-engine-light or at least some diagnostic codes stored that one could refer to - I've scanned this car every time she's been home and there are no DTC's. Should I assume that this is the standard "4th gear" issue and take the pan off for investigation or could this be some other issue such as the speed sensor causing the transmission to limit itself to a max of 3rd gear?

Just had new plugs put in and a tuneup so it's not that. Could something from the suspension work cause these symptoms?

I have a 2009 Santa Fe (Automatic 3.3 v6 AWD). I have found the last few days (-20 C) where my gear shift will move into all gears (R, P, N and D) but the car wont move in Drive. R, N and P all work fine. It does seem as the car warms up everything's fine.
The light in the dash for D does not light up either when not working. What this might be?

I recently bought a used 2010 Hyundai Santa Fe 4 cylinder AWD. Does the transmission have a fluid cooling system? If I pull a boat that weighs less than the 1600 pound limit should I drive in "D" or manually select 5th or even 4th gear?
