A few weeks ago, my transmission (automatic) started rumbling while shifting from 3rd to 4th and 4th to 5th gear. Shakes the whole car, like you're driving over a rumble strip. Only when the engine is hot. I read online that I should get my transmission flushed and replace the fluid, but should I be expecting the thing to go or is this a normal hiccup for the Santa Fe?
View 5 RepliesWife's Santa Fe has an issue with it's shift points. Its a 2002 with 148K on it, never has had a CEL, fluid is changed every 60K. Over the past few months the time it takes to shift through the gears is getting longer. What I am describing is not an actual delay between the gears, but rather how long it is starting to take to get the tranny to even shift. Sort of like how a vehicle shifts through its gears when your at a stop, and put the pedal to the floor and just hold it. it makes no difference if your barely on the gas or half way down, still takes a way longer time that it should to shift. It is slightly worse when cold, but still does it when warm. Is there some kind of temp sensor or vacuum line or whatnot that would cause something like this? When it does finally shift, its normal, tight, no slippage or delay. truck runs great other than this.
View 7 RepliesI hear a knock once in a while when starting my 2004 2.7 V6 Santa Fe and sometimes when shifting gears. I also hear it when going over rough rough, bumps, tracks etc... I'm thinking motor mounts 152k on the car.
My question would be how many mounts are there, exactly? I've seen three, but maybe another two for the transmission.
The front mount has some separation, but can't tell the others, as I haven't gone under the car with a flashlight just yet.
The majority of the knock seems to come from the driver's side. not sure if that narrows it down at all.
The wife was out in the Fe yesterday(2001 2.7 V6 Auto AWD) running at highway speed 80kmh before pulling up to a junction, when she pulled off again then the car came to a halt and lost all drive with engine still running ok. Luckily wife has the sense to switch it off. Tow trucked it home after she saw a puddle of tranny fluid under the car.
Any way it turned out one of the transmission hoses running from the cooler (right hand side hose that runs under radiator) managed to blow off the metal pipe.. don't know how, oem clamp was on and hose didn't split just came off! Needless to say this resulted in the tranny fluid quickly being emptied all over the engine bay and no gears.
So ive re attached the hose with new clamp and have drained what fluid was left in the pan..about 1 liter, and need to fill it up now and find out if it still works ok.
Now the manual says it needs 8.9ltr for a full fill but the question is will it of emptied the torque convertor as well so its completely empty or will it just of blown out the contents of the pan before stopping then just needing half fill.
What could cause a hose to blow off, they don't run at that high pressure normally, average hose pressure is normally 35-55psi from what I can find out so shouldn't blow off that easy should it.
I have a 2004 manual transmission Santa Fe. I've maintained it very well since new.
About 6 months ago I noticed it was getting difficult to manually shift gears. It wasn't grinding or anything, just "hard" to get it to go into the various gears while driving. Before, I could shift into any gear with just 2 fingers on the gearshift and it was smooth as silk.
I went in and had the gear oil changed. This was something I didn't even know needed to be changed and the guy said most people never do. They showed me the oil they took out and it looked more like black water than oil and smelled kinda funky. They changed the gear oil out, but still no difference, and in fact it's getting worse.
The best way to describe it is the only way I can really shift gears now is to find that "sweet spot speed" where the gears will change on their own (so to speak). I find it particularly difficult going from 1st to 2nd, such as when starting from a stop light. People almost rear-end me now as it takes me longer to get it into 2nd gear.
Once in gear it runs perfectly, no problems. The clutch seems to be working normally, except perhaps while stopped in 1st gear, it sometime seems to jerk a bit, and I find this most noticeable if I'm stuck in very slow moving heavy traffic with the constant stopping and then moving forward slightly and such.
It is almost impossible to "gear down" into a lower gear unless I'm at the speed where it would normally go into that lower gear on it's own. The best way to describe it is how it is possible to drive a standard transmission car WITHOUT a clutch if you shift at just the right time/speed. But I DO use my clutch, but if I'm not close to "that speed" it's really, really difficult to force it into another gear, and the few times I do try and force it, I'll often get a bit of grinding.
My buddy's 2001 7.3L F350 has had 3 transmissions. Rebuilt and used. Once the new trans is in he goes like 15 miles and then is starts shifting hard and grinding gears. What this could be?
View 8 RepliesI recently bought a 2001 Sante Fe 4X4, (my first Hyundai), that has transmission issues. It has about 135,000 miles on it. It will start easily, and go into Reverse just fine, but would not move in any forward gears. It would occasionally shudder a bit when put in 'drive', but only move forward a few inches. Recently, my mechanic backed it around, then decided to try it in forward again. This time it went forward a couple hundred feet, then quit moving forward. Do I need a new transmission, and if so, what vehicles use this same transmission? Or is there a sensor or valve that could be defective?
View 5 RepliesI just got a 2004 hyundai santa fe 2.7l 2wd model with only 92k miles that I just bought off of Craigslist anyways when im on flat ground and cruising through town the transmission shifts perfectly. However when i went up an incline to get on the freeway it shifted hard around 40 mph but after i got back on flat ground again I got caught up in bumper to bumper traffic and once it cleared it shifted perfectly all the way to freeway speeds of approximately 70mph. Then after getting off the freeway and picking my friend up when i went to get back on the freeway (another incline) it shifted hard again around 40mph.
View 15 RepliesA few years ago my auto transmission in my 3.5 L engine hyundai santa fe started shifting rough from 2nd to 3rd gear, i did a trans flush and changed the input output sensors, anyway last week it started again, so i just changed the input output sensors again, it did not fix the prob this time, do you think a flush would work.
View 4 RepliesI have a 2005 2.7L Santa Fe that was shifting poorly and getting stuck in limp mode intermittently. I read up on it and found that it was probably an issue with the input/output speed sensors. The codes confirmed my suspicions and I replaced both the input and output sensors. The codes cleared and the tranny shifted like a dream. Unfortunately after 2 days and 100+ miles the car suddenly started down shifting randomly on my way home from work. The CEL came back on and the car went into limp mode. Could the sensor have gone bad again? Or could it be the wiring harness that plugs into one of the sensors? I don't understand why the car would be fine for a few days and then all of a sudden be acting the same way.
View 6 RepliesOn older cars I've owned, this has never happened. But ever since day 1, my car has been jolting everytime I shift from P to R. (Yes I'm backing out). Is this normal? If not, what should I do?
View 1 RepliesMy friend has a 2007 accent with a manual transmission they said that they were driving and the transmission stopped shifting gears. The clutch pedal still has pressure so I don't think it is a master or slave cylinder issue. They freaked out and turned off the car and now the car will not start up again. Have any of you experienced anything like this before or know on this car where to start looking? I think the issue with not being able to switch gears could be a pressure plate issue but this would not cause the car not to start.
View 6 RepliesI have a 2002 Saturn SL2 (automatic). A few days ago it abruptly started thumping pretty heavily when shifting gears, especially going into reverse and 4th (or possibly 5th) gear. A couple mechanics told me the transmission is going, and that it would need to be replaced (but it would cost more than the car is worth. One said that we could try replacing the computer that controls the transmission, but it would cost ~$300, and might not do any good. Another said to try Lucas Transmission Fix. I've seen mixed reviews of it online, so I'm wary. Is it a good product, or does it just briefly mask the problem? Also, I looked under the hood, and cannot tell where I would even put it.
View 12 RepliesI have a BMW 523i SE AUTO (1997) 2494 Petrol. In auto transmission the gears will shift from 1st to 2nd and 2nd to 3rd but won't shift any higher. In steptronic/manual transmission the gears will shift from 1st to 5th without any problems therefore suggesting that the problem isn't the gearbox itself. Only very occasionally does the shift electronics telltale light appear on the dash, yet the problem with the auto transmission is continuous. A local garage specializing in automatics suggested that it was the gearbox inhibitor. I've today had this changed but the problem still exists.
View 5 RepliesEvery so often while driving in the city my car starts shifting rough between 1st-2en and 2en-3rd gears. If I stop; turn off the engine and then restart it stops. The car has 107,000 mi. and the fluid has always been changed as recomended. Do I have a shift selonoid going out somewhere?
View 2 RepliesLately I have noticed that the transmission is not shifting smoothly in the lower gears. I have 114K on there. Spoke to my service manager and he mentioned that it may need calibration. Doesn't sound right after all the miles?
View 5 RepliesI have a 2012 Sierra 1500 SLE with a 5.3 liter engine, 6 speed transmission and about 7700 miles. I have noticed that at times the truck does not seem to be performing efficiently and will not seem as smooth and transmission shifting is sometimes not so smooth in the lower gears. I have noticed that when I let the truck warm up for about a minute before putting it in gear, that all seems to go much more smoothly, but if I crank up cold and take off right away, then it tends to run not as smooth. I have even heard a slight "slap" type noise that I think is the transmission shifting when slowing down to make a turn at about 15-20 MPH. When I go to accelerate after the turn, it will sometimes slap as if it is hunting for the right gear. Obviously, I now let it warm up for a minute before I drive it. I have not talked to the dealer, but I probably will when I take it in for its 10K checkup.
View 1 RepliesMy 2000 Hyundai Accent, and it has started shifting gears when not traveling at the right speeds to do so.
I'll try to describe it the best I can, When driving I will be going whatever speed limit and all of the sudden it will make a winding noise (like when jumping on highway and pressing hard on gas peddle) and the RPMs will stall. It is like when shifting up, the car drives as normal but then it will shift down and pulls back (making a winding sound)
I am not sure what to do, I was told it seems like it may be the transmission is shot(I had the fluid flushed previously) and that it could cost over $1000 to get it replaced.
I have a 1991 bronco with a 351w and the e4od trans.. The transmission is shifting late and hard and sometimes when i let off of the gas to slow down it shifts between gears up and down by itself... The only lights on the dash that are on is the Rear Anti-lock brake light and the speedometer is not working either.. Where to start the trouble shooting to fix it?
View 3 RepliesI am coming from a 2001 Acura CL-S which is a 5 speed automatic, and that car wouldnt' change gears that quickly. I understand cars today change gears frequently to be in the best gear for fuel efficiency?
But I feel like my ES350 changes gears so much, even at the slightest speed change. Is this normal -perhaps it's because I haven't driven a new car since my 2001, 12 years ago! Even the slightest press on the pedal will downshift the car and into the lower gear, even on ECO setting. On my Acura, pressing lightly on the accel pedal didn't result in a lower gear, as I know the engine had more than enough torque.
I also love reliability, and this makes me think the transmission would have a shorter life span with all the shifting. I still haven't asked my dealer about how often to do tranny fluid changes (which I know is a different thread altogether about discussions about "lifetime" fluid).
2006 GX470, ~65k mi. When shifting from P to R, P to D, or R to D, the transmission often (but not always) seems to have to think about it a while. When it shifts fine it takes about 1sec for the transmission to change gears. When it's being cranky it takes ~4secs. There are no other symptoms.
