- 2007 Mazda 3 with rough shifting / No shifting. AT light comes on and drive letter goes blank and Drive number goes blank.
Here is a video I put together following the steps I took to trouble shoot and replace the TCM on my 2007 Mazda 3.
You can buy the TCM from here.

Rod Lewis great video!! I’m currently experiencing the similar problem on my 2014 Mazda 6, with error code P0882 on it. (TCM power input signal low) I cleared it after a week(after parked 3 days) the engine light came on again. I’m confused why after I cleared the error code it drives like almost normal, the only difference is the transmission’s response is slow than before little bit, shifting gears not fast as before, especially when driving on hill. I wonder if i can replace the TCM like you did and can you send me the link that I can buy the TCM, thank you
Hello Rod! I'm so appreciate your time for uploading this video, but one thing I would like to know, after replacing the TCM with a used or new one, did you reprogram it or not?
Best regard,
Hi Rod! My car got the AT light plus check engine. Got no lights for the gears too. You think it's the TCM? Car's got no power to accelerare.

This video is incredibly made. No annoying wait times, clear explanation, visuals on point. Thank you.
Josh Montano Thank you. That is what I was going for..
Thank you for creating a clear-cut instructional video how to replace the TCM. I had to have my car towed to a transmission shop and they gave me a high estimate do this for me. I'm going to work on it myself! I'm a DIY gal at heart and luckily I used to help run my father's transmission shop so I know enough to be dangerous 😅 I'm off to find a reasonably priced TCM that I don't have to program. Thank you!
Piscesgyal26 Thank you for the kind words. When I was making this video I hoped it would help others out. I never thought it would be viewed 200K times. 😎 Good luck! Please note that the TCM doesn’t need to be programmed.
This video saved me from being conned by the stealership. Thank you for sharing. My son's Mazda 3 is back on the road again :)
doublegolden 2018 So glad to hear that. 😎
Phenomenal step by step video!! I used to own an '07 Mazda3 and know how difficult they are to work on and you make it look so elementary. I'm sure you make a headlight bulb replacement look like a stroll on the beach
Just letting you know your video helped me fix my daughter's car by showing me how to DIY replace the TCM. Everything was exactly as you showed. Thank you!
I am glad it helped you! This is the reason why I did it.
did you have to reprogram the TCM when you bought the new one?
No. Just installed it and everything worked. :-)
Rod Lewis did you had to program it? Or provide vin ## ??
jcva1899 what does that fix the problem Mechanically I can understand electronically by replacing the part the tcm or PCM Power train control module AT Transaxle electrically fixing the problem mechanically meaning transaxle intermediate shaft differential how are those mechanical parts? The Computer can't just fix those of the broken internal
I own since new a 2009 Mazda 3 s hatchback 5 speed auto with 184,000 miles. I have been dumping money lately for suspension parts at all four corners and a trans module. I just got back from a 2000 mile Marathon trip in 50 hours. Car ran like a champ. Did not burn a drop of synthetic oil.
Excellent video. Bad TCM is common transmission problem in Mazda vehicles
Mazda 3 2007 2.3L, stuck in 2nd gear. TCM ending in E cost just under $1000 new from Mazda dealerships. Took a couple hours to fix because some bolts were rusty and not experienced. Problem fixed. Engine Light & AT lights are now gone 👍 Thank you for the very helpful guide Rod Lewis!
That is great news! You are the reason I made and posted this video. I can’t believe how many people it’s helped. 🤙🏻
Thanks for the video. I got to the point where you disconnect the harness on my own and then couldn't figure out how to unlatch it. Your video worked perfect and saved me a lot of hassle. I had a P0758 Shift Solenoid B Electrical code. Solenoid checked out fine so this was the next step. Works fine so far. Bought a rebuilt TCM on Amazon for 300.00
I am glad the video helped you out.
Did it fix your AT LIGHT AND DID IT WORK AND LAST?
Thank you so much for this video, I just bought this 2007 Mazda 3 and AT lite and check Engine lite came on, lost 1st gear and won't shift into 4th or 5th gears. I am thinking the TCM may be bad also. I will run the code tomorrow and hope that the TCM is bad. Looks like a easy fix. Thanks again. :)
I have a Mazda 3 2006 with the same problem was it the tcm
Could you fix it?
Did it work??
@@KingMateo575 no I had to by the Second and third gear solenoid’s inside the transmission oil pan. And that did fix the problem and been driving it ever since.
Rod - your video is too great !!
It's too bad the Mazda auto trans fix, or new replacement part ( L34T-18-9E1E) is so expensive !
Mazda should be aware by now that this is a long term reliability problem, and issue a TSB so Mazda dealers can rectify the problem without offering a very expensive transmission rebuild, or replacement unit as a possible solution !
My 2008 3 GT suffered the dreaded AT yellow light, and CEL (PO758) which cost $129 at a Mazda Dealer around 200K Kms -
as a result of this malfunction and reliability issue, combined with the inability of the dealer to properly diagnose the problem,
I will never purchase another Mazda product !
Totally Agree!! Is an incredible expensive part that although is changed there is no guarantee it will work properly in the long run..... Mazda Sucks
SUPER WELL DONE VIDEO!!!..I wish all repair videos were dona 1/2 as well as yours. Painless to watch...THANK YOU!
Glad you liked it! I wanted it to be direct at to the point.
Just removed mine to send away to be refurbished. This was really helpful!
Very well done. Especially for a first timer. I know it's a lot of work, so thank you!
Gear Whine Thanks! I tried to trim out all the wasted time to get the video short and still have all the information a person would need to do this.
Rod Lewis, well you succeeded. I used it to rule out the TCM and replace the VSS. Something tells me the TCM will also become a problem, but replacing it isn't a daunting proposition anymore. Thanks again.
Thank you! Mine just started doing this and this is the best video I’ve found on it so far!
Glad you like. I write technical procedures as a part of my real job. Used those skills to try to make it short, sweet and to the point. No wasting anyones time. 😎
As of Aug 2022, Mazda dealer was $1000 CDN. Thanks for video and will check Ebay link
Thanks for this video. I had exact problem but I paid over $1k for the fix.. the part my shop ordered is new and costed $760.. but the car runs like normal.. I wish I could just try to order the part and attempt to fix my own, but I already brought my car to the shop prior finding a solution online.
Bummer. It was an easy fix. You sure could have done it yourself. I have had moms write me and thank me for this video. It helped them fix their daughters car. Really couldn’t imagine it would help so many people. I feel truly amazed it has been viewed as many times as it has.
God damn mazda dealer! They've told me I needed a new transmission when my AT light came on. It was only the TCM and and a transmission fluid change that my mazda needed. This mazda I have, will be my last one I own.
Hi I have mazda 3 2004 and I have same problem with AT light and my car doesn't go in 3rd gear it goes only in 2nd gear... I went to repair shop and he sad you need to replace new transmission...i am worried about it...could you plz help me
Excellent Video! My sisters 2008 Mazda3 Grand Touring 2.3L has a U0101 code also and I had her order the Rev E module. I'm about to install it w/this videos help in about 2 hours, looks pretty easy!
shaeet let me know how it goes.
Rod Lewis worked great! Took less than 30 mins and no codes at all once battery was hooked up. I drove her car and immediatley noticed loud wheel bearing drone from the right rear so I guess that's my next project
I did this. Bought mine off amazon. Mazda wanted $800 for part. Amazon was $400. Did this 3 years ago when car wouldnt shift above 3rd. Still working now
Hey how’s it working still? I don’t wanna pay 600 bucks for one
Still working. Sorry for late reply. Just went over 200k miles.
My fiance's mazda 5 was having some issues (check engine light, AT light, shifting issues, and a P0753 code) and the mechanic said it was a failing TCM. The code indicates a bad shift solenoid A which could be caused by low trans fluid or dirty trans fluid so Im going to flush and replace trans fluid first and see what happens. will post results.
Thanks for this helpful upload, I imagine the change on a mazda 5 would be very similar.
any updates?
update for code p0753 same problem? im going to buy a tcm instead of the transfluid
do you fix your mazda 5 ?
great video, Rod. Thanks so much. You should do more car repair videos. This was very very good all around.
mike Layhew Thank you so much. I can believe this video has been watched 111K times. It feels good to know it helped a lot of people.
Hey I have the same problem on a 2011 Mazda 3, imbginna try this hopefully it works I'll keep you posted. By the way great video dude, 👍
Did you get the problem fix ?
Hey this video really help out alot i was having problem for weeks now and today i finally did for myself
I’m glad it helped.
Congratulations the best video I've seen of how to change the transmission module that great labor saving
Did you use the video to replace the TCM? If yes, how did it go?
My father has one of these, his is 2006 mazda 2.3L, man, I'll tell you, this makes me appreciate my Saturn SL2 1.9L....lol Mazsa is a good car, don't get me wrong and hate on me but it's just so much easier to work on. Even with the mods I've added. My father's TCM is bad too, slams into third from fourth or fifth and the auto trans light comes on. it's a very expensive part to replace too. Anywhere from $400 to almost $800 bucks at the one mazda dealer in my area, just for the part....lol Oh, BTW, the engine has to be ice cold to truly test if it's fixed.
Nicely done, step by step. Unfortunately this did not fix my problem, but still great video. Keep it up!
Excellent video. Good job. Make more videos on this vehicle
Getting code for p0762- shift stuck on solenoid C, I just replaced solenoid C and drained/filled with new ATF fluid but problem still persists. You think I should just try replacing the TCM now? car is fine 1-3gears, but has trouble in the 4th. it can catch on sometimes, but slips mostly. @rod Lewis
@John sir? Pls reply. Mine gets clunks and all but ive notice that it goes away of i reset the battery but goes back after few minutes. My mazda 3 wont shift to 3rd gear unless my speed goes around 130kph
Been having the same symptoms, rough shifts, won’t go past third, at light comes on then turns off🤷🏻♂️ Just ordered a refurbished replacement Tcm from eBay. Error code kept saying output shaft sensor, but replaced it and still having the same symptoms. Been checking the internet and different forums, everyone’s saying it’s the tcm. So wish me luck boys, I’ll keep y’all updated 😂🫡
Please reply back with your results. Lots of people have done this and that is the best reward I can think of. It’s easy! You got this!
@@rodlewis276 just changed the part and car drives normally again. 🙏 thanks for the video
@@FULLtiltSENDER I told you you got this! 👍
My 07 Mazda 3 has the at light on, but No codes are set? Actron cp9180 scanner. What scanner do I need to read codes?
Great video, especially the part list. it was very helpful, I had the solenoids replaced and it did not rid the p0753 code. I removed the TCM today , and will install the new refurbished eBay one tomorrow. hopefully it works, I miss driving my hermosa.
Danna G did it work??
Ivan Munoz yep!
If I fix that would it let me put it back to the M and can I see the gears 🤔
My 2006 Mazda 3 2.3L just started doing that. I was just going to buy a new transmission.
I'm pulling a P0791, AT light is on, Manual mode is not working.
Car does shift but it lags to shift.
TCM Malfunction?
Speed sensor?
xCalcifer87 No that code is a shift solenoid problem I believe.
@@rodlewis276 I'm pulling an Intermediate Speed Sensor issue with a P0791
Nice video
I have a 2007 Impala SS and no gear shift indicator was coming on and the car drives like your pulling a 10,000 lbs yacht. My speedo ramdomly works with traction control light on. Getting TCM replaced and flashed at the srealership.
So I’m hearing 2 different things does anyone know if the 2.0 2007 madza 3 has a TCM because someone saying it doesn’t but I get the exact issues a TCM would have
Hi, i have a question
I bought a TCM module with exactly the same serial number, it is identical to the damaged TCM, do i just have to replace it ?
Don't have to reprogram or something similar ? Thx
Doesn’t need to be reprogrammed.
Good job on this video
great video ,, my Mazda 3 is doing the same thing , I think you just saved me a lot of money ,many Thanks
Have your issue been sorted out?
Did you use the video to install the new TCM? If yes... how did it go?
Rod Lewis it worked great ,and it wasn't hard to get to the TCM, I bought the new TCM online for around 550.00 at a alternative Mazda dealership, the one by my house was asking 750.00. so it pays to shop around.hope this helps.
What do you call the two sets of wireset next to the battery holder
What if the lights on but the car still runs fine? Electrical problem?
My 2008 mazda 3 2.3l starting having transmition problems where when i turn it on the engine light, tansmition light, and the traction light all come on and it no longer shows me what gear I am in. when I put it in drive I have a majo lack in power and it feels heavy as if I am trying to drive with the e-brake on. Took it into an auto repairs shop and they called out the tcm being bad and want to charge over $1200. I found the part online for $200 however and can easily install it myself but when I told them that they said it would need to be calibrated as well. would I really have to calibrate it and they're just bs-ing me, or could I find a way to calibrate it myself?
GARBEZ5150 There was no calibration needed on the part I bought.
leave the car running for 20 min on idle after replacement. Calibration is necessary so the change of gear goes smootly. leaving the car idle for 20 min will do that all 'automatically'. That's at least what i have been told.
Great VIDEO! ANNOYED THAT THIS PART IS $300 USED OR REFURBISHED WITH A CORE EXCHANGE! or $500-850 NEW! THAT'S CRAZY.

This is less than $500
is there any particular reason to remount the tcm in a spot where it may overheat again? i was thinking of mounting it on my battery box.
Remember the engine moves with respect to the frame. I am not sure if there is enough slack in the harness to accommodate mounting to battery box. Proceed with caution. :-)
People in Latin America are changing the position to move the TCM inside the "cockpit" just adding longer cables. sorry for my english
Apparently some guys are mounting it to the brake lines that run along the fire wall. Ordering the part this week to make this fix, but not sure about that as a mounting point.
Did the AT light turn off automatically??? I had the same exact problem. I replaced the tcm and all the symptoms were fixed! But my AT LIGHT is still on. Which is weird
Yes. It reset for me. Please check error codes. You might have multiple issues.
Ok thanks, but i have 2 questions: does it have to be program or straight swap, how do i get the part number if i got the other one before taking off the old one, i am planning to order it from junk yard, i drive the car to work every day
Does not need to be programmed. Part number L34T-18-9E1E
Mine came on but gear light never came off the AT light never started flashing. But it did turn off after i turned the car off then on again
What error code are you getting? That is what is important. Automatic transmission can have lots of different problems. The error code will point you in the best direction. If you get the error code in this video then it can help you. If you get a different error you’ll need to search for that video.
@@rodlewis276 not sure what code havent checked
Can you drive the car when the ctm is messed up?
Im asking just because im thinking about purchasing one of this cara.
It depends on how messed up it is. It will eventually leave you stranded on the side of the road and calling a tow truck.
Some people say, you have to have it programmed by a computer either before or after you install it. Any suggestions
See comments below in this thread. No it doesn’t need to be programmed.
does mazda 3 2005 2.3 has a tcm because i look under the battery and there is nothing ?
or this tcm is include in the computer please help it has the same issue as the one on this video .
I have a 2007 Mazda 3. AT light is on. Shifts to 2nd gear right off. Shifts hard between 3rd and 4th gear. error code is DTC P0772 [FS5A-EL]. Possible cause: shift solenoid E stuck on, control valve stuck, TCM malfuction. what's the most likely suspect?
I want to buy one but the last letter is "C" no "A" i just want know if is compatible
The higher the letter the newer the revision. As long as all the other numbers are the same it should work. Good luck!
I have a similar problem. I changed the TCM 2 days ago, it did not fix any problem, unfortunately. My car always shows: check engine and AT lights. Very rough shifting from park to reverse and drive. It would not shift over 3rd gear. Manul shifting not working. Does any have any suggestion?
what about the sensors around the Computer module tcm sitting next to the computer and on the transmission can those be the cause of no shift limp mode only drive in 3rd don't show gear change then I pulled out my Tcm tonight cause I have AT yellow light automatic transaxle light on And also my TSC yellow car pictures swerving line icon on the dashboard by the mph and. Odometer Custler
did you figure out what was wrong?
so i had changed mine. it was okay. for 2 days. and now it is back . would the soeed sensor be at fault?
My traction control light is on my AT light is on and the car is running weird it isles high like the RPMs are real high when my car is put in reverse my engine shakes
Just got mine in from Mazda swag before even watching your video. But a little more expensive.
I was told the tcm has to be programmed to your car, is this true and if so, how can that be done
If u get it from the dealer its plug and play. Got mine from mazda online a little over 500
Hi just wanted to know what you did it supposed to fix all the symptoms cause i have the problem of th driver letter indicator goes blank.
What happens if you AT Flashes and No Codes Per Mazda Only a slight Flash?
No error codes while AT is flashing? What are your symptoms?
Doesn’t the OBD reader give you a specific code, so if the code gives you P0720, then is it a tcm?
I think that code is shifter solenoid. You can google the error message.
@@rodlewis276 thank you. However even online information hasn’t been very direct and I’ll check it out
My girl having this problem she just bought that part but do she gotta go to the dealership to get programmed?
DeMario Burrell see 2 messages down. No. It doesn’t need to be programmed.
@@rodlewis276 ok thanks
Can't find tcm under the battery box, and my power steering went off and problem with starting only jump cable, is it tcm ?
Mine just started this yesterday. It will blip, and i guess reset and be fine for the rest of the drive. It has yet to get where the AT light stays on. I just bought a module today at lunch, and should be here Friday evening. I just hope it does not get worse in the next couple of days.
Chris Penuliar sell it! I waited too long and now i might be out all trade in value.
Well how did it go?
Great video. It was fairly simple to swap out besides the bolts that you can't see on the TCM. Everything seems to be running fine. I'm just worried that i may have caused some minor mechanical wear by driving it till the new TCM came in. So i'm not sure i'm hypersensitive to every road surface or if it may be something in the tranny slipping or lugging, but I can't complain too much. Overall everything seems back to normal. Thanks for the video.
Awesome video sir. But how did u test it? or did u just guess and prayed that it worked. Be nice to know for the diyers out there. Thank u
Jason Chavez I just plugged in the new one like the video shows. When I started the car back up. No error code was present. It’s just that simple. 😎
@@rodlewis276 thank u sir. Just wondering because it's a tough module to get to do simple voltage measurements since everything is in the way. I guess if u take the battery out and the tray and hook a jump box to the terminals and do test from there before making a 300$ call or more.
Can the TCM be rebooted?
Where did you get your tcm for madza3
On my mazda 3 2008 model, the TCM is not located down there. I checked all over and still can't find it
Can some one helps
dose 07 tcm module fit 2010 mazda hatchback
where did you get the tcm for 2010 mazda? I have 2010 mazda 3 with this problem.
Is it still working? I just got a Mazda and the Tcm went out I sent it out to some company to get it re programmed worked at first and within a month it’s back to what it was before
landon marler I bought a new one, and yes it’s still working.
Where did u buy ur Tcm I’m having same problem but lil expensive
See my pinned comment.
My AT light is on And my TCS/DSC vehicle with the swerving lines Amber yellow lights are on I just thought of my car coming out to work that night and then the car struggle to go anywhere struggle to's take off this is before I bought the car I noticed I never had the gearshift light up in the center consul but in the cluster it's fine that lights up but with the AT light on automatic trans axle light Malfunction failure lights must be something related too the Cv axle on the passenger side goes into the intermediate shaft that been clicking ever since I bought the car like something is broken I never got the chance to change that one out because it's two pieces maybe that has something to do with the computer thrown the AT light on from the TCM. Please correct me if I'm wrong but won't just replacing the powertrain power control module AT pcm computer won't fix the problem isn't there something mechanically that's broken that causes the light to come on too? I'll be my first guess fix the mechanical then worry about the computer or at least try toO diagnostic the parts before replacing it then going to the electrical part then diagnostic that
How do you know if it is not the starter problem when it doesn't shift properly? First thought of trouble shifting is starter.
- from newbie
I have a Mazda 3 2007 and my car shifts from 5th gear to 3rd gear on the freeway and the at and check engine light comes on. Could this be the same issue? Would I need to replace the tcm??
Sounds like the same issue as with mine. You need to check the error code to be sure.
Rod Lewis the check engine light always resets once I turn the car off
Tanisha Beanez In the video at about 56 secs it shows the OBD2 code reader. This will tell you what error you have. If you get the same code as what is called out in my video..... Then the rest of the video should help you out. If you get a different error then the solution you need will be different. If you don't have a OBD2 reader you can buy one for < $30. Or you can typically borrow one from a auto parts store. The port to plug into is located on the driver side to the left and down from the steering wheel.
Rod Lewis I have codes 735 732 722 what's the possible issue if you don't mind answering?
Is this the fix for a hard shift from 3-4 gear also? 08 Mazda3, replace this part and it’s good to go? I read a lot about the ecu needs to be reflashed for the fix??
Bluegill20 This is a fix for error code indicated in the video. The TCU doesn’t need to be programmed. Just plug and play. I have heard of dealers using the programming to try to scare people from doing it themselves.
Hi, I had the AT light on and the CEL on too . I replaced the front wheel speed sensors and wheel bearings and then had the TCM repaired from G7 computers they fixed a faulty resistor so I plug it back in and thought the problem was over but its still doing the same thing so I plugged in a scan tool and did a live date and notice that the transmission shift solenoid B was not working and never gave me a code that is was bad . so I'm hopeing that if I change the shift solenoid B that if fix the problem and clear the CEL. Anybody have any thoughts?
great job ill do the same on mazda 3 2006. but the question is what will you do with the old part will you return it for core charge or resell it ?? thanx for the video
was wondering if it was the same layout for the 2006 ?
Buenas tardes mi carro marca la AT cuando le doy switch; pero no me marca ningún codigo en el scanner que podría ser??
La única falla que hace es que golpea cuando lo pongo en D, todos los cambios los hacce bien
hi Rod Lewis
i got mazda 6 2008 2.0 liter petrol (UK Model) ..all simpton are same with engine light ..do u think thats the same issue (TCM)..?
Fault Code P2709 (shift solenoid f electrical)
Quick question for you guys .. I have 2008 Mazda 3 hatchback also with a TCM that needs replacement.. let’s say I drove the car for a few days .. tranny still seems fine .. although my sensor goes on then a couple minutes after driving it goes away and drives like normal .. will that eventually mess up my transmission? The TCM is shipping as we speak
You need to look at error code your car is giving. If your error message is same as in my video then your TCM is having communication errors. This is typically from the PCB getting so hot the soldering remelts and components start to become disconnected. Heat cycles can make the problems intermittent but it will eventually get worse with time.
hey can you help me please i have an 06 mazda 3 with the same code U0101 aT light on but it jerks very violently when put into reverse only is this the tcm?
Do you get the AT light on the dash? The code you listed is the transmission losing communication with the TCM. it's most likely the cause.
hi thank you for your reply ! yes it has no gear selection like the green square doesn't show.. it has AT light on the dash along with the check engine light. the only code that shows is U0101 lost communication with the tcm. i want to replace it but want to make sure before i spend on a new tcm... also only kicks when put in reverse.
jose valles I totally under stand. It's a pricey item. I can tell you that it completely fixed my issue. I have been running with the new TCM for a couple of months now and zero issues since I replaced it.
yes it is unfortunately im scared it might be a solenoid or any wiring but i dont get thrown any of those codes therefore my best bet is the module. did u also have the reverse kick?
by the way this video helped me throughout the whole process of taking out my old one nice job!
Can someone tell where the tcm is located on a 2008 Mazda 3 2.0. It's not where it is on in this video. Thank you
I was told by a guy at the Mazda dealership and he was saying something about it being in the dash
Dose this also the cause of the tsc light too come on
Can I get a used tcm or is that not advisable?
nice video, very informative ! Thank You
Thank you. I am glad it helped you.
My mechanic said “If it’s that you gotta program it else it won’t move “ is this true ?
No. It does not need to be programmed.
having this same problem with my 04 any recommendations on where can find good tcm for cheap
TheDatnikajay me tooo please let me know if you find anything

Does it need to be reprogramed or no just plug and play
tabby babie The one I bought was plug and play.
Rod Lewis my husband bought it today and can you be leave the freaking dealer was like oh we have to reprogram it I was like you a Daymn lie! Because it's plug in and play I seen this TH-cam video! Already omg I wish you could have seen there face it was like oh snap she knows her stuff now my Mazda is back running smooth I'm soo happy thanks to this video!! Lol we even have the same part number lol that's how I knew they gave me the right one sadly the part was 720.40 but it's ok at least my car runs now only took me and my husband 30 mintues to put the part in
tabby babie Please make a note of that dealer and do not give them anymore of your business. They charged you $700 for a $450 dollar part. I am so glad this video helped you! I could never imagine when I was working on my daughters car that over 150K people would watch my video. This is what technology should be used for. Helping each other. Your story alone makes my effort worth it. 😎
Rod Lewis yes I really am happy about you posting this I have the same! Down to the T car you guys have I was sooo happy when I saw this video I changed everything with my husband it only took us 1 hour tops and yeah I called and told the company what happen and they are sending me a check of about 300 dollars back because of what the Mazda dealer did
how much tcm mazda 3 2006 model 2.0 l
What error code did you get? I got PO753. It said shift solenoid a but it could also be the tcm.
Anthony Igania look at 1:04 to 1:06 on video.
Do you know of Mazda moved the placement of the TCM on the 2009 Mazda 3 or is it in the same spot?
I have the same problem, but error p0753, should I change the same part?
P0753 is a solenoid error. I think. That would be a different problem.
I just changed mine aperently they go bad because of the heat from the transmission this is my second one replacing olot of people say sip tie it to the brake hoses so it can last longer but I went an put some felt pads on the bottom what u think ? Awesome vid
Rev E uses higher temp soldier, but anything to reduce the heat that the part sees should help life time of the part.
Does
This also clear the Tsc that's stuck on with the AT yellow light
Is the tcm a auto parts part or mazda part
Damien Taggart The part I used is a Mazda part. But I did not buy it through a dealer. I bought mine on line.
thank you. i will take this video to the mechanic that "fixed" my car's problem... smh my question is nothing happens if i keep using it after that lights turns on.. ??
i have the exact same problems !!!! but will this cause the check engine light to turn on ?
Yes. Usually just the "AT" light will initially turn ON by itself and then the "Check Engine" light will turn on soon afterwards (usually within a few miles).
Do you know if this works for error code P0772 solenoid E as well?
Alex Chujo No. That is a different problem with different hardware solution.
@@rodlewis276 what problem and solution would be p0772 solenoid E
