Mazda 3 Transmission Problems



  • Perhaps, but people still come here to find answers. So it is helpful, even if the original post was 4 years ago.
  • I purchased a 2006 3 about a yr and a half ago from my dealer that I work with in dc. I typically buy his high mile cars off him at a good price. Recently the trans starts to shift into 3 from 5th and the eng light comes on. Sometimes the AT light comes on then goes off. This has been an issue for about 3 months or so. My dealer reads the codes tells me to get a speed sensor code p0715. Replace that and it drives good for about two weeks. Eng light comes back on my dealer tells me to go to mazda dealer ok then I take it there and they come up with new code p0734. tell me to get new trans and spend 3k on a 4k car. My trans guy says that its a brain issue or bad speed sensor. He is still researching issue. Car dives fine. Every now and then eng light comes on then I park car and it goes away. Once and a while it shifts into 3 but only once in last month. IDEAS?

    Hopefully, your "trans guy" can clear up the issue as you appear to be getting multiple codes (P0715, P0734) referring to the transmission.

    What kind of mileage does your 2006 have?
  • I need to circle back to my trans guy after the holidays. He does this for a living 20 plus yrs. At dealer by day and nights and weekends his own shop. He thinks its the brains or replaced senser is the issue the dealer
    that took it to stands behind saying you need a new trans. The car has 97k on it. I am a mech and I am along with the person that I work part time with a master mech are getting reddy to pull off t belt water pump. Madza North Amer I plan to call them back on Tuesday. The first time they where no help. IDEAS?
  • I have had my Mazda 3 i touring since November 2009 and have done 18000 miles. My clutch burnt out too. Dealer said that this was normal wear and tear and not covered under the warranty. I have driven manual cars for 22 years and this is the first clutch that has ever given out on me. I called Mazda Customer Service line and then basically said tough its not covered. Going to complain to whoever I can.

    Mine went at 33K (I have postings back up in this forum somewhere.). I paid $850 for a new clutch and resurfacing of the flywheel at an outside Japanese car mechanic. (incidentally right after that, one motor mount blew - that was covered under warranty).

    About 2,000 miles later, I traded the car in. I did not want to deal with anything else.
  • I have a 2008 mazda "3" 2.3L (without turbo) that I have owned for about 3 months now. The car has 33000 Miles on it and is a blast to drive. Here is my issue... when the engine and trans (auto) are cold, right after starting in the morning my car seems like it has tons of power. The acceleration felt in first, second and third gears is amazing. The shift points (not using tiptronic) are crisp and powerful and the car will really throw you back in the seat.....That being said, after the car has run for more than 45 - 60 seconds, or I have driven more than 3/4 of a mile it's like my car loses a lot of the performance I just mentioned. The engine temp guage at that point is about 1/4 past cold on its way to the usual 1/2 way point where it almost never gets hotter. At this point my car seems to have soft shifts and the acceleration in 1st, 2nd or 3rd just is not as powerful. A few times when accelating hard on a warm engine from a dead stop I thought I felt a shutter or stumble from the trans but not sure if the tires were slightly slipping. All in all the car drives very nice - but I want that feeling of when i first start it up.

    Couple of things... the strong acceleration and quick shifting is very reproduceable every morning but ONLY while the engine is cold. Shutting down and waiting 5 minutes does not work. I do not have any check engine lights or trans fault lights on and I just had the trans fluid flushed at a Mazda dealership 2000 miles ago because I thought the fluid was very dark and dirty looking (new fluid still looks good - and the problem I am having was there before and after the fluid flush, if anything the car was a slight bit better after the flush). If I use the tiptronic manual shift and let off the gas like shifting a manual the trans catches and shifts nice and quick like you would expect. I have had a trans shop put a scanner on the trans but they found nothing.

    I know, I know what some of you are gonna say - should have bought a speed 3 with a manual trans - wish I would have now but this car is what I have and I like it.

    Is this the way Mazda engineers designed the car?

    Based on your description I suspect there is nothing wrong. The shifts in an automatic should feel smooth and nearly imperceptible. If the car is starting to stumble that could caused by the spark plugs, wires, mass air flow sensor, or other issues. A diagnostic may be a good idea at that point.

    MY crystal ball says your next vehicle will be a manual. ;)

    After hearing various complaints (shift delays, gear selection, harsh shifts, and outright failures) about about Automatic transmissions from many manufacturers (and the costs of repairs when out of warranty) I've got just one more reason to be glad I'm a self-professed manual transmission bigot.

    True, in this era of hydraulic clutch linkages there seems to be a higher incidence of premature clutch failures (improperly configured or insufficiently bled at the factory?) than ever before (still a very low percentage), but on the whole the latest generation of automatics seem to be far less robust than the TorqueFlights and TurboHydromatics of old and many times more expensive to fix than putting in a new clutch. As autonomous there seems to be a manual transmission in the future of many automatic drivers these days. :)

    I have the exact problem w/ my 06 Mazda3. The car shifts into 3rd and the only way to get it to reset is to pull over and turn off the car then restart. My car has been doing this once in a while for the last 9 mths. The AT light now stays on and the Manual gated shifter doesn't work at all. I also had the code checked and it came up as P0715. My mechanic gave me the option to get it check out by the Mazda dealer. I'm sure they want to replace the tranny. I fully believe it is a sensor/computer problem. The hard part is going to convince the dealership that. I too am looking for some advice.

    P0715 = Input/Turbine Speed Sensor Circuit Malfunction

    The code indicates a bad speed sensor which is affecting the transmission.
    The question is it only the sensor or is it more than that?
    Unless you trust your mechanic implicitly, you may want to get a second opinion.

    Being a 2006, are you still covered under your Mazda warranty?

    I have a 2009 Mazda 3 with 68,000 miles. For a month now I occasionally (20 percent of the time?) have a problem shifting into second gear with my manual transmission. Mazda told me all they could do is change the transmission for $3,000 because they don't dig into them. A transmission shop couldn't find a problem. The only thing online I found is to double clutch, but with it only happening 20 percent of the time, I don't think that's good answer. It will grind and eventually shift but I'm worried this will damage the gear or linkage. Any ideas?

    I've run across complaints such as yours upon occasion on various Mazda related boards, and each time I do I recommend a simple gear lube change to Redline. In every case (and I do mean every-single-case) the change of the lubricating oil has fixed the issue.

    Keep us posted on how you make out. :)
  • Hi Sunset 19 looks like you haven't logged in since your problem with ur Mazda was fixed, I am in the same predicament. I am after my warranty, got solenoid C stuck code, they replaced it. Driving on freeway went down to 3rd gear and stayed there almost causing a wreck. Took it back to mechanic saying code is gear 3 incorrect ratio and transmission needs to be replaced. I was hoping if you happen to login that you could tell me if you shopped for your transmission via online, etc. and/or how did you find a low cost with good warranty replacement.
  • Mark Coltrin again, I have a Mazda 3 -2006 with 100k on engine now. I have the Mazada 3 Trans, Not Clutch, trans, I had this issue come up on and off now for 8 months or so. I have a trans guy, and he states that the , brain has a comm problem with the trans. The car wash value is 3k. The dealer wants 3 k for a new trans. The AT light now stays on , and sometimes the engine light comes on , but It will go away. Mazda north america has no clue , nor does the dealer. We replaced what needed to be repalced , but same problem. Car drives great , I will just re set code wend I trade in.

    "I have the Mazada 3 Trans, Not Clutch, trans..."

    What does that mean?
  • "I have the Mazada 3 Trans, Not Clutch, trans

    Mazda Calls it "Mazda Speed".

    Are you trying to say you have an automatic transmission?

    FWIW, I've never heard of a MazdaSpeed transmission, just a MazdaSpeed car, most of which have true manual transmissions.

    Edit: I just did a little checking, and unless I'm missing something, Mazda has never called an Automatic transmission a "Mazda Speed" transmission. Furthermore, all MazdaSpeed3 models have been sold exclusively with a true manual transmission.
  • Yes, I just say that I just say that , sorry!

    Seems like it's not only Mazda North America and the dealer that has no clue ... :D
  • I fully believe it is a computer problem. I felt uneasy buying a new tranny. When I disconnect my battery it resets and my car shifts thru all 5 gears for awhile. then goes back to the gear 3 incorrect ratio. If it was tranny, wouldn't it not be able to shift at all? Or am I wrong? I took my car out of the shop before replacing transmission, had to pay $450 for this. I STILL have a broken 2007 Mazda 3 that has a Gear 3 incorrect ratio. I am looking for a computer tech for cars who can check this out.

    This same exact thing is currently helping me right now, they recommended me replacing my transmission because two of the the bands were missing from the gears. It was going to be 2500 to replace the bands so they suggested a brand new transmission because its 3000. But when they jump started my car, it erased the codes and the light turned off. I'm waiting for the light to turn back on because its still under warranty from the dealership just not for very long. I was wondering, when you apply heavy acceleration does your car take a long time to switch from 3rd to 4th gear, mine will switch when I hit speeds of 75-80 mph?
  • To pay 2-3 k for a trans is not worth it for a 3 k wholesale car. My trans guy says that I should keep dring car. I just replaced all belts and water pump. Car runs strong. Its a madza problem that they dont want to help with. When I dump car I will re set all the codes on car.
  • What you are experiencing is a computer, or sensor failure. The bands aren't missing, and if the codes where pulled, they didnt write them down. Sounds like a bunch of inexperienced techs. When the computer gets mixed signals, it goes into "limp mode" put the trans in a gear, usually 3rd, so you can get to a dealer. If you clear the codes and it shifts fine through the gears, then goes into limp mode, I would say you have a problem with a shift solenoid, or speed sensor, or something like that. if the speed sensors are not functioning properly the will make the computer think it is broke. And most shops, from my experience will try to sell you a transmission, no matter what is wrong.
  • Hi
    My daughter has a 2004 Mazda 3 - When she put's the car in reverse it feels like the bottom of her car just fell out or that she was hit from behind - Also, both the "AT" and "Engine" lights are on... Can you tell me what the AT light means and what is possibly wrong with her car? It has 90K miles on. When I took it for a test ride, it seemed as if the car wouldn't shift gears automatically and her "manual" shifting isn't working either - if I remember correctly, there was a light on displyaing the No. 1 - as if the car was in 1st gear manually
    Thanks for your time and help - Look forward to hearing from you soon

    This is EXACTLY what my 2004 Mazda3 did to me. Had to replace the transmission.. $3000 sorry!!
  • Hi,

    I've got a similar issues, I'm not seeing what your resolution was. My car is still at AAMCO.

    My issue sounds similar. I am driving on the highway, the car jerks and my transmission lights on the dash turn off. The gear and gear number lights go dark. A few seconds later it all comes on on 3rd gear, the car revs and the AT light comes on.

    They've had my car for 3 weeks. It's been at the shop, a mazda tech looked at it, the computer codes were downloaded, it's been to a dealership and is now back. They think it's a short. But it's become a time life mystery.

    The computer checked out ok. BTW

  • Mark again, this is a mazda problem and they wont own up to it. The person that I need to talk to , the madza techs, mazda will not let you talk to them. Its not a trans problem, its a brain vs senser problem. To buy a new trans is a waste for a 3k for a 2006 (3) with 100kmile car. I not sure what the at light means? Thansk
  • Well, after a long 2 month suffering with my 2007 Mazda 3 which I was ready to trade-in with a $2500 ended up with a new transmission! and it runs like a baby again. I couldn't come to grips that I needed a new transmission at 83,000 miles. I would disconnect my battery it would reset and shift gears for a little while then go back to the 3rd gear stuck ratio so that was why I believed it was a brain/sensor/computer thing. I had changed the pulse generator sensor at home and it still didn't shift. I read every forum, researched, called Mazda mechanics (they wouldn't help).

    I had already mastered the art of driving with 3 gears to work and local driving which was insane. My stepfather finally came to the rescue asking how long was i gonna wait to fix my car or trade it in? He called his mechanic for quote, they found a low mile transmission and fixed it. His mechanic said Mazda 3's are always having tranny problems, he said, "no good". Honda, Toyota, Nissan - no Mazda!! lol, i'm laughing now. MY Nissan ran 250k miles still like brand new when i got new 350z was great til it got totaled, I thought what a great lookin' Mazda 3 this is i had to have it, sunroof, blue...but has cost me this pain in 1 year of having it. Well for now, it is back on the road it is a great looking car and the inside is perfect for me..I have it working as background in television so not a total loss.
