Hi. I went the same route as you and sent mine to g7 and got same response with an untouched TSM sent back to me. I just got it back yesterday and it did not fix any problems. I then have got the mazda 5 diagnosed at a transmission shop and they say it is the TSM that is bad. Question: how did you get yours programmed or did the dealer you bought it off do that? Thank you in advance.
Alot of these places claim they can fix your TCM. All they do is replace some capacitors and resolder pins the board. A lot of times this will not fix the TCM. It got damaged by the heat from the transmission.
I'm having the same problem I called the dealership and the part is 850$ . I then asked if they could give me the part # and they wouldn't. I found some on Amazon for around 250$ . I'm afraid it want be the right one. When I scan the car it says TCM lost connection
Don't know if you'll be seeing this comment six months after posting this video. But I wanted to ask is your Mazda still running fine after installing the new module? I'm getting ready to work on a mazda5 that has the same exact codes you had at the beginning and I was following your whole journey with the videos you made and I'm interested if the module and that up fixing for sure your issue. Thanks again for what you've done you've already been a great help
Hey there John, I watched both of your videos on fixing this issue on your vehicle. I wanted to know if your Mazda was giving jerks while driving or if the light AT would come on and then off. Let me know please. I'm going thru the same exact problem and I'm thinking in just buying a new tcm. Thanks for your videos it really helps out.
No, the TCM does not have to be programmed on 2006 thru 2009 Mazda 5; I can't say for any other years; I don't know. But understand that the TCM is different for 2006/2007 (4 speed) and 2008/2009 (5 speed) models.
@@johnhermann762 thank you! I ordered the part from the Mazda dealership in NH. I am basically following in your footsteps here. Hope it fixes mine. Is yours still functioning properly?
@@andreww8529 I can almost guarantee that it will fix your problems. You may have bought it from the same dealership that I did out of New Hampshire. Good luck and would love to know how it goes for you.
@@johnhermann762 I absolutely did buy it from the Mazda dealership you suggested. Here in Ohio they were on back order from where I checked. Thank you for saving me time looking for best price! The transmission shop wanted $1373 to replace it!
After installing new TCM, how did you managed to program? I have Mazda 5 2009 and my TCM need to be changed. I can buy it online and replace it but what i will be do for TCM programming? Do it require programming?
TCMs for models 2007 thru 2010 do no have to be programmed; I don't know about other models. Note that 2007 and 2008 are 4 speed trannies; 2009 and 2010 are 5 speed; they are different TCMs and are not interchangeable.
Hey John is your mazda still working? I am in the same situation after sending my tcm to allcomputerresources for repair, but still fails intermittently on code p0753.
Hey I have the same car anyway I could contact you I’m not sure if it’s the trans or the tcm which I changed and flashed but I still see check engine light and I’m having a problem with first gear or drive
I sent my TCM off to have it repaired, and they did not find any problems with it and they claimed to have updated it with flashed firmware. The TCM was not fixed by their work, but the TCM was bad. Replacing it fixed my problems. I can almost guarantee that will be your problem as well. Just pay the $500+ to get a new one from a Mazda dealer; not one from China.
Hey could you post a link so I can order mine please

Try ordering from Werner Mazda in New Hampshire. They had the lowest price and shipped quickly. Good luck!

One other question I forgot: did you have to have your new TCM programmed to your vehicle and if so how did you go about that?

Having problem with my Mazda dimeo 2007 no reverse nor fword
No idea. It probably has a tcm but don't know if that's the problem.
Can you link the website where you got Tcm
All I did was googled "Werner Mazda New Hampshire"; www.wernermazda.com/
What's your mpg?
Right now, nothing; car is being repaired. Normally get around 28mpg on highway and 20 city.
