Hi do you have an idea on how to change the transmission oil? 2008 Mazda cx9

How did you add it My 2011 just started having this problem and I just stumbled across this video

@@saliston hi did you ever figure it out i have the same issue

Did it work? I have the same car with the same problem 😭

I also did not change out the trans fluid as I just had this done about 9,000 miles ago.

After a couple of weeks a very slight shudder, almost unnoticeable came back in 4th gear. Because I had not used the Mazda recommended transmission fluid I decided to flush the system using the transmission pump by disconnecting the coolant lines. The old fluid was not red even though it was only installed for a few months. By flushing it this time and using the JWS3309 fluid and one tube of Shudder Fix there is absolutely no sign of shudder in any gear now. If that ever changes, I'll post it here. I'm glad it worked for you too!

Benjamin, how is it now after 9 months?

how is the car now?

@@Chance2Go Hi Chance, I know this is 6 years late, but would you mind do a video of how to flush transmission fluid like you mentioned here?

Change spark plugs.

عندي مثل مشكلتك،، هل يوجد حل نهائي لهذه المشكلة؟؟

I have same problem,, is there any siluotion???

Thanks for the hint.

Aún tienes el problema o lo solucionaste? Yo tengo el mismo problema use el producto lo redujo uno poco el problema pero no se quitó

Kathryn Davis Did it work?

I also replaced the plugs and coils in an attempt to fix the problem. I thought there was a slight improvement but it did not solve the problem.

I recently had this issue come up on my cx-9. Drive it for a little while and when you begin to park or place it in reverse it begins to stutter, even at one time the car shuts off/stops running

It only works if your problem is fluid related. If it’s mechanical related, it won’t work. This worked like magic on my truck.

Rob Mann mine lasted until I traded the car due to other problems a year later

Reicce Bass any process on how you did it?

@@r0nnick - easy to add through the dipstick on a 2010.

@Dave Howard= into the transmission, so trans dipstick. I used the entire tube.

Let me no how u go I have same problem 2007 model too

@@emilymacfarlane2889 I tried it and it worked (kinda, but not really) for week and the problem is back. It must work better for cars where the issue is new. I think my gearbox is a lot more damaged so it isn't fixing it. I even used two tubes. I'm going to have to pay for a brand new torque converter. Almost 2 grand. Yikes!

Oh ok I just bought mine this week I'm taking back to dealer tomrpw and there mechanic is going to take a look hopfully they can fix the issue since I've only bought the car 2xdays ago

@@emilymacfarlane2889 Yeah, good luck. It's such a costly issue to fix. But the method in this video doesn't actually fix the problem, it just masks it for a little while.

I'm hoping they do a transmission service it's not a bad shudder so hoping that will solve it

It's been awhile...what was the update?

I traded it 5 years ago for a new CX-9 after the transfer case to transmission spline failed due to lack of lubrication. The new car is much better than the 2009. Mazda gave me a deal because I argued it was a factory defect.

@@Chance2Go Right on thanks for the update, chance. I'm thinking about trading it in in its current status.

@@chrismiles2000 If you can make a case that it is defective, call Mazda USA. They gave me employee pricing which was about an additional $1,500 off of the best deal I could get from the dealer. Mine was 10 years old and had over 100k miles and they still did it.

Can you please tell me where to find the transmission dipstick? I’ve been trying to find it for the last hour. 2011 CX-9

Joe T. Hi Joe, yes use the entire tube. My 2008 had a traditional dipstick. Later years have a screw hole like you describe. I since traded mine for a 2018 that I love but this solved the problem for a year for me.

@@Chance2Go I appreciate man, thank you so much for the quick reply! I'm gonna give this a shot and cross my fingers!

Are you changes?

Yes pour it in. I also recommend changing the transmission fluid but only use the recommended JWS3309 (I think) Mazda fluid. Amazon has the shudder fix product.

@@Chance2Go where do we get in from.malaysia

So did you add the Lube guard? ...or just the Lucas?

Try Lucas Trans Addative. I used it for hard up shifts(2nd and 3rd gear)on my 2004 Pontiac Motana,worked wonders!! Must suck out/drain a guart of trans fluid then add a quart of Lucas!

Did you fins out how? I have the same issue

Can't find the stupid dipstick

I did several of the things you tried and was quite relieved when a $3 tube solved the problem.

I think I did add one later. It's been nearly 5 years since I had that car so I don't remember exactly.

Not sure. Try adding the Shudder Fix fluid. I eventually traded mine for a new CX-9 because both the transmission and transfer case needed to be replaced for $7,000. Sudder Fix prevented the shudder problem though until the new problem.

I traded my 2009 for a 2018 about 6 months after this video when the transfer case failed. The 2018 seems much better engineered than the 2009 with far fewer problems.

@Chance2Go I had to drive 100 miles the other day to airport it was driving great but my AT light popped on the last 10 miles, I shut it off picked up family and drove back the light was off then popped on, did your AT light go on. I'm praying 🙏 to hit lottery 🙏

You can try but if one didn't fix it, it is more likely a bigger issue

mxP443 did you use the Mazda recommended transmission fluid? If not, flush it again. Shudder Fix worked instantly. It took care of 95% of the problem. When I then flushed the old fluid for the correct specified fluid then added one tube again, it solved it 100% and has remained fixed for several months now.

The shudder problem did not return. In January the transfer case went so I lost AWD. When I took it to the dealer they confirmed that but after removing the transfer case found the splines to the transmission were stripped. It would have required replacing both the transmission and transfer case at $7,000. I called Mazda corporate to see if they would help even though it was a 10-year-old car. They wouldn't help cover the repair costs but did offer employee pricing on a new car. That got me an additional 4% off the price of the car plus all the other incentives. So I bought a 2018 CX-9 and love it. The turbo 4 cylinder has more torque than the old 6 cylinder and it gets 25% better gas mileage! I am in the mid 20's MPG now. Hopefully this one has a better transmission and transfer case than the old design. Time will tell...

Walt van de Kust t shaft between the transfer case and transmission wore out due to lack of lubrication. It would have required both to be replaced. In research I found this to be a factory defect. Even though it was over 10 years old I contacted Mazda and they offered employee pricing on a new one. It got me about an additional $1,500 off of the best price I could get. The new CX-9 is far superior to the old one and I’ve had no issues in 39,000 miles so far.

Yes, that's it.

@@Chance2Go I’m having difficulty getting the torx head cap out. Any suggestions?

@@EJR898989 No, I am not a mechanic just a previous 2008 owner and now own a 2018 CX-9 which is a much better design.

Yes, and you should have used Mazda transmission fluid. I tried another brand and learned I should have used Mazda fluid.

@@Chance2Go awesome thank you, I put some in this morning and seems to be subsiding. I will get the mazda fluid my next flush, thank you for responding.

Mazda removed the dip stick around that year. I think there is a bolt that covers the hole to add fluid into the transmission. You may need a mechanic to help locate it.

mrem mrem , I don’t know. You can try the Shudder Fix but I don’t think that will fix it.

Hola te funcionó?

I traded my 2008 5 years ago. As I recall, the gear number displays as the transmission moves through the gears.

@@Chance2Go thanks but you think as money just stays at 6 could that be a serious problem

@@andyessien6685 Yes if it is actually in 6th gear all the time. If the indicator says 6 but you can feel it shifting normally, than the indicator has a problam and I think that is less serious.

@@Chance2Go you're right that's just the problem I have with my gear so what do you think I'll need to do because I feel it shifts from the speedometer it goes from one to two but just the indicator problem, and also I have a slight problem with slow acceleration but that started today car starts well but no pressure when I hit the gas pedal you have any idea.

@@andyessien6685 I am not a professional mechanic so I don't know how to solve that problem. I traded the CX-9 for a new one in 2018.

The shudder did not return but I had another problem with the transfer case that caused me to trade in the car one year ago. I bought a new CX-9 and love the car.

@@Chance2Go please how can I change the transmission oil

@@Chance2Go what was the other problem?

@@AaronAviion The splined shaft that connects the transfer case to the transmission stripped due to inadequate lubrication. Both the transfer case and the transmission had to be replaced at $7,000. I complained to Mazda USA because it seemed like a design flaw and they offered a discount on a new Mazda so I traded it.

The factory does not have a recommended change for the fluid. It seems smoother though since I did at 100,000 miles. Only use the Mazda recommended fluid and flush all of the old fluid out. Draining the pan only gets half of it out. I tried different fluid at first but didn't completely solve the problem until I went back to the Mazda fluid. I am not sure about the other problem that you are having.

Chance Parker thank you chance. there is only 85k km on my car so u think it is still early to change transm. oil? thx again for your responses. rgds

Chris b have you had any results?

Most likely the transfer case failed. If the splines between the transfer case and transmission are stripped the transmission will also need to be replaced. That happened to my 2008 CX-9, this past January. in this video and the dealer wanted $7,000 to replace both. Instead, I contacted Mazda Corporate and traded it in for a new 2018 CX-9. Because the car was so old Mazda wouldn't help fix it but they did give me a discount (employee pricing) on a new one. I am very happy with the new car.

Chance Parker if the transfer case failed will it be able to be replaced? Or need to replace transmission?

curtis reese my 2008 had a dipstick. Later models did not. I think there is a bolt you remove then use a funnel.

My uncle has a 2008 but he said his doesn’t have a dipstick. But I can find where the bolt is. But you just add it to the transmission fluid?

curtis reese , yes, add it to the transmission fluid

Ok thank you so much

It lasted about 8 months but I eventually had other problems that caused me to trade in the car

Chance Parker hey, what were the other problems that forced you trade it in?

The spline between the transfer case and the transmission failed. The splines were stripped due to improper lubrication. From what I read this was a design problem. To fix it would have required replacing both the transfer case and the transmission at $7,000! Mazda Corporate is or was helping fix these if the car is 2009 or later. Mine was a 2008. Instead they offered me employee pricing on a new car. I liked the 2018 CX-9 so I took it and like everything about the car. It's much more refined than the 2008 and I did like that car until I had the transmission problems.

Chance Parker does it happen only it AWD versions then? I got FWD 135k miles on it and no fluid has been changed since it was produced. Curious if I had to change it if I dont find anything wrong with the car yet.

Only the AWD has a transfer case. I would recommend flushing the fluid with the Mazda fluid. It's a lot less expensive than a new transmission.

I have several times. The Automatic Transaxle light and Check Engine like will pop on at the same time and my vehicle gets stuck in 3rd gear. Hooked mine up to a scanner and said it was the Shift Solanoid Circuit High.

No, I did it at first without changing it so try it. If it does not completely eliminate the problem then change the fluid.

AWD

@@Chance2Go ok thank you

Did you fix it with the valve body replacement ?

It doesn't claim to fix a bad transmission. It appears to work for a lot people. But it probably won't work in every situation.
