Toyota Yaris Transmission Problems



  • snowmansnowman Posts: 540
    I really like the new Yaris and I've been lurking to discussion forums to read what others say about. This particular topic about transmission oil change interval took my attention.
    I like to pass my 2 cents on the technical aspect of the discussion.
    Unlike what some auto mechanics and manufacturers say, anything beyond 30K tranny oil replacement interval is an invitation for costly repair bill.
    Conventional tranny oil will start showing contamination signs @ after 20K usage. I usually reach that point @ 18K. I perform the flush myself, pretty much every year.

    Unlike EU manufacturers, US manufacturers don't even mention brake fluid and PS fluid replacements as maintenance items in their manuals. However, they are crucial items.

    So, the point is, don't believe everything you hear or read. Do your own search and make desicison.

    Yaris is a new design, consumers shouldn't be surprised if some problems arise. But overall, it is backed by Toyota.
  • Ok... I got a response to my question (new yaris lemon?) but really it didn't answer my question. There are so many Yaris owners... can other people please answer that post and tell me if what my engine is doing is normal? And if so, why does it do that? The other poster said it was because of the self-adjusting transmission(?) I have not heard of that, could that be it? I am very concerned about this. Anyone?

    If you are that concerned about it, take it back to the dealer. It is still under warranty, isn't it?
  • My auto liftback also does the same. I never thought it was a problem, just the way the car drives. Don't know why... never tried to find out because it just doesn't bother me. :confuse:
  • I don't know about the self adjusting trans thing. This is the first I've heard of that. However, my wife commented that our liftback sometimes seems to shift "funny." Now, I don't really notice it when I drive, but she has commented on it more than once. I think the shifting is electronically controlled and the way one applies the accelerator might affect how the transmission shifts.

    I would suggest 2 things. First, check the owners manual for information on the transmission. The manual sometimes provides some unique details about the car that you would not otherwise know. Second, I would definitely take it to a dealer and let someone else drive the car while you ride along. In that way you could point out the problem and maybe determine whether it is related to driving style.

    If the characteristic is present with any driver and the dealer just blows you off I would take it up direct with the manufacturer. You still might not get anything done, but at least it would be reported. You never know when something like this might lead to a recall some day.

    )) "I don't know about the self adjusting trans thing. This is the first I've heard of that." ((

    You do lead a sheltered life... ;) Without getting into the quagmire of certain Toyota AT problems covered in other forums, all modern automatic transmissions are "self-adjusting". They're now under the control of computers to continually set and adjust shift quality according to engine RPMs, temperature, vehicle speed, engine load, and, not least importantly, operator driving style - aggressive drivers get a somewhat firmer shift over time, while more temperate drivers enjoy a settling-in of consistently smoother shift quality. Once a predominent pattern is established, the shift control computer will automatically compensate for long-term clutch pack wear to maintain the established shift quality until it's rebuild time. Prior to computer controls, automatic transmission shift points were modulated strictly by engine intake manifold vacuum - and doing so worked fairly well to a point. But I'm old enough to remember my dad taking the family '55 Plymouth with its two-speed "PowerFlyte" transmission in for a periodic band adjustment every 12,000 miles where the technician would adjust for clutch band accumulated wear to re-establish the proper shift point feel. How many of you reading this remember ever having had to do any such thing?
  • I'm a little hesitant to post in this discussion, but the flame war above seems to have smoldered and gone out and my question is definitely about a Yaris transmission problem.

    My Yaris Liftback M/T has 5900 miles on it.

    This weekend (driving around San Francisco) and today (driving home in very heavy traffic) I noticed the gear linkage squeaks when moving from first into second. Inside the cab, the squeak isn't too loud, but sitting on the driveway with the engine off and the door open, it's very loud. The shifter moves smoothly, and it doesn't make noise moving out of second or shifting from third to second.

    Has anyone else noticed this problem? Does it sound like impending doom?

    The driving conditions for these two days were way out of my norm (open freeway commute, short distances in town).
  • It seems that a common error amongst us Yaris drivers is leaving the car in third gear rather than drive. It sounds like the problem is due to the confusing design of the shift mechanism. I would like to make sure that I'm understanding the problem and solution here.

    The shifter does not just move up and down but also rocks left to right. As I understand this, if you leave it pushed to the left it's in third gear but if you push it to the right you are then in fourth gear?

    That's weird. What could possibly be the reason for designing it this way?

    Yaris46 is showing his age....old thinking....old school thinking, big on emotion, dillusion, and superstition.

    Toyota says to change the tranny fluid on an as neede basis...this can mean going 100,000 miles or more between changes, your situation depending.

    I have had several Toyotas that I NEVER changed the tranny fluid on, and all of them reached 120,000+ miles with no tranny issues.

    And the reason Toyota suggest little or no changing of the fluid is NOT to sell more cars...this is stupid thinking...but the reason is because if the fluid is okay (regardless of milage) then changing the fluid is just waste, regardless of how cheap it cost to change.

    If going so long was so bad, then Toyota would have millions of complaints which would translate into a really bad reputation, massive loss of sales, etc...of course this is not the case...Yaris46 is big on emotion, low on facts, and reality....sad.

    Just learn to drive your car...this really is not an issue...this is a simple training issue...just be mindful for a few days, and like me, you too will stop keeping the shifter in 3rd....this issue stopped being an issue for me after a few days.

    This is not a design problem. Mercedes and Chrysler use this "gated" design, and it is a benefit, not an impediment, as it helps prevent mis-shifts.

    Read the manual! ;-)

    I remember having the bands adjusted HAHA I'm a "old Guy". This, along with others is why I got the 5 speed MT. I am sick and tired of trannys just failing one day for a whole lot of money and time getting it repaired. The MT's will give you years of warning IF they are goint to go out and give you extra power as well. The Yaris is so light and quiet that with my radio on I can't hear the engine and I am trying to save the clutch so I am trying to keep the RPMs down at take off. Well I have stalled it in traffic about three times now. Dang I hate I guess it will just take some time. This is my first MT in years.

    You are an exhaust port. ;)
  • lhansonlhanson Posts: 268
    Don't feel bad, I did the same thing for the first couple thousand miles and still ocassionally until I sold it to my son and got an automatic transmission. Now I don't have that problem any more.

    I always thought that automatic transmission were better than manual transmission

    My Corolla did that, and I just lubed the pivot points where the shift cables attach to the transmission. 5 minute job. I would take back to your dealer.

    Rule of thumb always......go by the service manual specifications! Factory manual is the best way to go. I have seen way too many mistakes in Haynes and Chilton's!

    A good mechanic never assumes he/she has the correct answer. If I went by history, it would be fill to the level. But I would not assume, I would check the service manual. That also gives you the correct service interval and fluid type.

    That factory manual may be expensive from the dealer, but it is well worth it in the long haul.
  • girlcarbuildergirlcarbuilder Baton Rouge, LAPosts: 218
    You are correct for some makes, like Ford! On many of our foreign cars, we run a synthetic oil 10k miles with a good oil filter. Always run a WIX, never a Fram. Expect to pay at least $5 for it. Don't believe me, cut them open and see why. Historically, Toyota's are very true to the maintenance schdules. I have even seen a few that did not have proper oil changes hold up well.

    But the bottom line folks is good lubrication extends the life period no matter what you drive. As for another good tip, many fleets are now installing an inline filter and oil cooler for automatic transmissions. The inline filter has a magnet in it and it has a service life of 10K miles. Best to locate it before the cooler. Change it regularly and you will no tranny headaches to speak of. Oh, I have only found these parts at the transmssion supply houses like Transstar.
  • girlcarbuildergirlcarbuilder Baton Rouge, LAPosts: 218
    Well an ocassionally deal like that is what I do with our rebuilt engines during the first five hundred miles. The high vaccuum helps suck oil past the rings to seat them better. 500 to 1000 miles that is not necessary, because most of the setting is in place. If you switch to synthetic oil, expect to be back to oil burning for a while because it is a better lubrication material. With synthetic, you will be well broke in with excellent gas maileage by 10K miles.
  • girlcarbuildergirlcarbuilder Baton Rouge, LAPosts: 218
    Yes, I have seen Toyota auto tranny's with over 200K with no problems or service. I would suggest a fluid fliter change at least every 100K for insurance. I would also consider the new inline filters as well. Those inline filters are being used by many fleets now. Change them every 10K though, and you will never have that tranny apart from what I am hearing! Check with Transtar Transmission parts on net for those filters. This is a transmission parts major supplier to that trade. Real question is, how long do you want to drive that car? Many of mine are 20 years and older still in regular service! The mileage is way up there on one.
  • girlcarbuildergirlcarbuilder Baton Rouge, LAPosts: 218
    Okay, so far I have been seeing nothing but good on the Yaris.....I want to hear the dirt!!!!! I am getting older and my wrench turning days are numbered. I figure even with my skill, I can max out another 10 years out of my fleet here. Prime movers being an 89 Mazda 323 and a 86 Toyota Tercel. Both are manual five speeds, hatchback models. The Tercel layout under the hood is most clearly related to the Yaris. 1.5 liter with a 5 speed. I am getting 40 plus mpg in it after the recent overhaul. I see some drivers getting a 42-44 on the Yaris. Not bad given it is another 1000 pounds of weight compared to the 86 Tercel! Not yet enough to make me jump and buy, but its getting there.

    As always. Watching the junkyards tell me what holds up and what does not and why. I do not expect to wait 20 years for answers on the Yaris given Toyota's reputation. Yup, I still find a few 20 year old Toy's out there!

    So tell me the dirt on your looks like a buy to me or more like a steal at 12K. Sure beats rebuilding.
  • girlcarbuildergirlcarbuilder Baton Rouge, LAPosts: 218
    Ditto on Fram. I use WIX filters. Many an engine I have torn down to examine after using WIX is clean as a whistle. Another note, stay away from Quaker State and Pennzoil. Both cake up over time with chunks of Parafin. I became a believer on synthetic oil after the last new engine past the mileage of the original one and is in much better condition. Very little blowby on it. I have even found engine seals to be in much better condition. We changed a four speed tranny out for a five speed on the 89 Mazda because of cost of gas. I changed the rear main as well at 100k miles on that engine as a precaution. It was just as pliable as the new one!
  • Should be picking my new hatchback up tomorrow and you bet it`s an automatic.And Yes I`m fat,american and lazy.But after spending 9 to 11 hours in a `07 tri-axle Mack dump truck I don`t want to have to spend my time shifting my way home.If that makes me a spoiled worthless american,so be it. :)

    My wife got a used Yaris, auto transmission, hatchback, owners manual missing.
    There is a button? on the transmission console just above the Park light. In my wife's car this button is broken - there is only a piece of white plastic there - and I don't know what should be there and what function it has. Can anyone help?
  • nivardnivard Posts: 3
    Should there be a light to indicate which gear I'm in? - this is a Yaris with automatic transmission.
  • nivardnivard Posts: 3
    While using the transmission to slow your vehicle does put strain on your transmission in certain circumstances it may be your only option.
    When faced with a long , steep downhill stretch a driver who rides his brakes will burn his brake linings and boil his brake fluid and ultimately lose his brakes entirely. Obviously using the transmission to maintain a safe speed is the only thing to do in this situation.
  • i bought my 2008 yaris in december..5 speed manual, and after about a month or so i noticed my third gear would grind as i came out of second. after driving like that for a day or so i noticed it wouldnt do it if i engaged the clutch as i came out of second and into third, or came out of second or put it in neutral long enough for the rpm's to drop to an "idle" rpm then into third. basically it would only take the gear when the rpm's were at an idle. i dont think its my in-experience with a manual although this is my first manual, i was smart enough to read my owners book first and followed the instructions in the fact that i didnt stay in gear to long while driving it as instructed for the first few months. two or three weeks ago i took it to the dealership to get looked at (i also had a frayed drivers seat).
    they took it for a test drive, called me back down to the service area and said they were ordering me a new seat and a new transmission!!..and a replacement car would be given to me at no cost to me while the work would be done, and they would call me when my parts came in, then sent me on my way...which is all well and dandy, but..i wanted to know if anyone else has had a similar problem.
    and yes i engaged the clutch enough for the gear to be able to clear to enter third. many many times al the way to the floor with un-necissary force.
    the car was brand new when i received it..11 miles and three were from my test drive.

    I have that same problem with the squeaking from frist to second gears with my yaris manual transmission. I was wondering if I could do it myself the lubing of it to stop the squeaking? Is it hard to get to it if your not a mechanic or don't have the tools or should I just bring it back to the dealer if it that hard to get to it to lube up.
  • I have had the exact same problem! When I took my car in for the first oil change at about 6k I had the shift problem. They didnt take care of it until about 16k miles, they said it was the synchros after I took it to a clutch specialist and had my husband go in. Now I'm looking at 32k and the exact same problem. My difference is that you had the entire transmission replaced, I just had it tore down, synchros replaced and put back together. Are you having anyother problems in your car besides that? Toyota wont admit that there are any known problems.

    Re: New transmission after two months?!? [cverosko]
    I had similar problems to those above at 9000. Under factory warranty they fixed it quickly saying they put a new transmission in.
    Now 70000 miles later I developed the same problems-- under extended warranty they made repairs but demanded I also replace the clutch (not covered). It took 2 weeks... I did get a replacement car.
    i put 40k a year on my car... how common is this transmission problem? I thought I could run a toyota to 200k... obviously mine won't make it and the next repair will not be under any warranty.
