Mazda CX-7 Transmission Questions



  • carlitos92carlitos92 Posts: 458
    It took me many months to get used to my old 1.8 turbo Jetta, although I think it was a little easier being a manual transmission... Basically, I would have to floor it off the line and then get OFF the gas when the engine hits the juice at 3500, or else "bad things" would happen to the tires... :blush: I assume we'll all get used to our CX-7's over time. Hang in there, guys.

    Just broke 1000 miles on my GT AWD and it has included a couple portland to seattle round trips so plenty of highway to play with the tranny. 6th is certainly built for speed and fuel economy but doesn't have much hill climb. Its quick to downshift to 5 on almost any incline if you are below 2500 rpm (below ~70). I have found that if you just get a little running start and get your revs above 2500 it will take many lesser hills in 6. I find that manually keeping it in 6 below 2500 just sucks the mph off because its out of power and if your not willing to gun it a little and instead hover around 2500 the turbo kicks on and off leading to a jerking ride. By the way its pretty happy doing 90 in 6 up almost any hill.
  • Hey, I have just over 5000 miles now. I am sure it is not because I am getting used to the turbo...LOL .
    I still love my Mazda except for the jerking at highway speeds that irratates the crap out of me, and my a/c shut down a couple of times. I still don't know why or what happened.
    It's good to know someone else is having the problem, (misery love company) and Mazda knows about it. I was on the road a lot recently and the only time I had a chance to visit a mazda dealer they had never heard of any problems nor were there any dealers/ factory messages yet.
    I hope they do in fact fix the problem if not I will get rid of it. Yes it's that bad. It would hurt either if Mazda somehow trys to make this right. I didn't want to buy a test vechicle. later

    Does anyone else seem to feel that in normal suburban and rural driving, the car remains in 5th gear too long?

    I manually shift to 6th above 38 mph because I think that lowering the rpms by 200 revs over the long run will save just a mite of gas. Not that I am frugal, but as long as I cannot drive above 55 mph in a severely policed area, why use the oomph that a lower gear will provide.

    Any remarks are welcome.


  • Having dealt with dealership service for quite a while, how do you approach them on fixing gearing or shift points if they claim they don't know about it. The impression i get from reading online is that the consumer knows much more than the guy at the service desk. Im not sure if that is good or bad. It may be bad because through the normal course of driving, the cars habits may just be the cars habits and we tend to freak out and have anxiety over the tranny? lol Or its good because we are much more informed. Is the tranny a real issue on the CX-7 that Mazda is working on or is that just a nice comfort the consumer statement to make us think Mazda is working on the car? I switched from driving an Accord V6 2 door and I will be honest and say the MAzda engine does not feel at this point as smooth and or as solid as the Honda engine in terms of shifting/jerks/ etc. But this is my 1st turbo, and i would def say the learning curve is up there in a CX-7 interms of using the gas pedal, dealing with turbo lag, and learning how to use the throttle in tune with engine response.
  • In the morning when it is cool out, when first starting the CX-7, the idle is at 2000 rpm and will not go down until the car is put into gear with a nice thump. Dealer says this is normal. I find this hard to believe that you put a car into gear at 2000 rpm. The morning initial start is the only time this happens. Is any one else having this happen?
  • It is normal for the car to rev higher on cold mornings; this the the EFI system's way of warming up the engine. (If you're old enough, think back to the days of manual or automatic carburetor chokes).

    My CX-7 only does it for a few minutes, during which time I'm usually trying to defog the windows, change CDs, get buckled in, etc. Shifting into gear at 2000 rpm is your choice, but nothing to worry about - that's what a torque converter is supposed to handle, and once a day during the winter certainly isn't going to kill it.

  • This is not uncommon and or a problem whatsoever. Its your engine warming itself up. You shouldnt drop it into gear until the tach gets closer to 1k. This shouldnt be foreign to you, all cars do this if they are cold and have to warm up.

    I let my 7 idle for about a min or 2 till the tach levels as 1.

    I always just put my cars in gear and creep out of the neighborhood figuring that it's better to warm all the systems up gradually by driving it gently instead of taking off with a warm engine and cold tranny, etc. Excessive idling is bad for the engine and exhaust system too (link).
  • This is my first turbo so I'm not familiar with idling the car before turning it off. Is this a real concern? Do I always need to be concerned about this or just after interstate driving or heavy acceleration?

    I have 800 miles on my CX-7 and the jerking transmission at highway speeds in nearly constant. Have never felt anything like this on any car, new or used. Extremely irritating. I believe I will also call Mazda USA.

    Recommend you visit your Mazda dealer and take your service tech for a ride and demonstrate the problem.

  • I believe the reason is for the turbo fan to run to cool itself. I think its only a necessity after driving for an extended period of time.
  • I too HAD the same problem. There is a bulletin on this and my dealership did a reprogram on transmission control module. The first time it still wasn't quite right. I took it back today and they checked it out again and did another reprogram. This time it worked. The tech at my dealership was very open and even had the service manager do a search for any bulletins. He did find it and communicated with me the whole time I was waiting.
  • I have the same problem - very noticable and annoying. I plan to take the car to the dealership. Would you share with me what dealership you took your car to so if my dealership is difficult I can have them contact yours to discuss how to fix it? Thanks.
  • Heritage Mazda in Owings Mills Maryland.
  • same thing with mine, GT CX-7 AWD. planning on taking it in to the dealer. engine hesitates as soon as it shifts into 5th and/or 6th and stays rough at what seems like all cruising speeds between say 45mph and 65mph.
  • I just had a problem with my CX-7 transmission sticking in 3rd gear. The engine light and AT light came on the friday before Christmas. I had to wait until the Tuesday after Christmas to take the car to the dealership. At that time the AT light was off but engine light remained on. The dealership said that they had to reprogram the control module. The following day of driving, the car was stuck in 3rd gear again so I took it straight to the dealership while the AT light was on. After checking the car out, they said they had to replace the control module and now the car is running OK. I just want to pass this info along so you are aware of what needs to be done to fix the problem. I will say that the service at the dealership in Brandon, Florida was great and every time provided a loaner car with no question asked. That's service.
  • My CX-7 makes a 'klunk noise' when the gear shifts from 1st to 2nd. You can also feel it on the gas pedal. It's louder and more noticeable on the pedal after it's been parked for a while but it always happens even after driving it if you turn the engine off and turn it back on. My dealership tried flushing the transmission and resetting the computer to no avail. They're out of answers and is setting up an appt for me to see the regional technical specialist for the west coast. Does anybody have a similar problem?

    If this just happens only on the first shift, (after shifting out of park) Then it is most likely the ABS system
    testing itself. That is the only time I have heard a similar noise.
