Mazda 3 5 tcm failure and replacement...do not re-post my video

[@car-u-fix-it8070]

My TCM was bad.....but my transmission torque converter "solenoid " was bad as well. TRANSMISSION CODES WERE: PO733 AND P0744 was solenoid.........

[@Yousef.shreem]

How buy this part

[@ibmtpx24]

My 2015 Mazda 5 has 75k miles on it and I will relocate the TCM just to prevent it from overheating. Thank you for the video.

[@talvalon999]

Very well done! enjoyed your video.

[@anilramnauth4531]

This is common problem with Mazda vehicles. TCM goes bad - the AT and check engine light come on . Good video...

[@car-u-fix-it8070]

Thanks

[@1silvervespa]

Should be a Class Action law suit.

[@bobsoft]

Why? Electronics cant fail?

[@kernelsanders9003]

⁠@@bobsoftno because Mazda purposely placed an sensitive electronic part on top of a hot transmission, it should definitely be a class action law suite

[@car-u-fix-it8070]

TCC solenoid was fine.....its the other solenoid body hidden next to fire wall....."the connectors " are very loose and it causes problems....not solenoid. Unplug and spray them.....will make a video about sensors, price and location soon

[@novaboy55555]

I recommend changing out that transmission mount while in there!

[@atharvashinde1368]

when replacing the TCM, will any TCM from a car with the same transmission work? Or do the years need to match, will it need to be programmed?

[@car-u-fix-it8070]

I don’t think so, as far as programming goes, disconnect the battery and it takes up to 100 miles to learn

[@TeamYELLOW17]

My mother purchased a used Mazda from the Roger Beasley Dealership in Central Austin on 10/17/19. They sold her a 2007 Mazada 3 with a faulty or failing TCM(which they just replaced for FREE today 11/19/2019).This is after I drove the car for roughly three weeks with gear shift issues. At this point, the vehicle is driving fine. My question is (I am being proactive) do you know if the hard shifting on the car causes any other issues?

[@car-u-fix-it8070]

We drove our car for about 1 week , I have not noticed any issues yet.....it drives fine and we just took a 200 mile trip ...no issues......but our car had the transmission serviced twice and our mileage is only 80k.....

[@car-u-fix-it8070]

We have driven the car with new TCM for 7000 miles....no trans issues.....depends how many miles your car has and how many weeks prior to the sale it was driven with issues....and the service given to car....transmission wise.....service the transmission if it has not...hope it helps

[@car-u-fix-it8070]

I replaced the vehicle speed sensor and codes have not comeback....will update later

[@jaimelima2420]

Hey Raul, Thanks for the video. It was concise and helpful. Just curious, what other upgrades you had to do in your Mazda 5 2009 ?? ... I also have one with 115K that bought new and this TCM was the first real problem I had. Now some general comments of the TCM problem - from my working experience with similar ones. It seems that a solder is failing or specific discrete component in the board - my guess us the soldering because the problem survived multiple revisions of this part. It is also seems to temperature related for sure. To me the strongest evidence for that is that many people report changing their transmission fluids and the problems 'disappears' for few days probably because their systems run a bit cooler. I also did some quick temperature measurements. On top of the transmission > 85 C seem possible during heavy loads. On the alternate place I got 51 C. This with 29 C outside.

[@car-u-fix-it8070]

Hello Jaime....I did: cross drilled rotors, heavy duty rear shocks....bushings.....and better break pads.....wider tires and the important one: lower control arm silicone fill......

[@badtexasbill5261]

Is your dash noisy? My dash is constantly squeaking and its quite annoying. Its worse in the winter.

[@deemaximillion6019]

My mazda 5 2008 model is driving/shifting but at moments it just starts shifting in and out of different gears on its on jerking. (While in drive) could this be problem

[@car-u-fix-it8070]

Sorry to reply late….I forgot my KZbin password…..locked out….scan the car for codes …your local parts shop might help for free….let me know what codes you have…

[@mywork1862]

When replacing an old TCM with a new/used TCM, does the part numbers have to match?

[@car-u-fix-it8070]

Not necessarily...as new TCM's are updated so new TCM's will have a different letter at end or begining....my new tcm did not match in numbers but I input my year and make and model on website I ordered it from...and was sent the latest tcm.....double check as not all TCM's are made equal.

[@anthonyigania8465]

AT symbol only appears sometimes with symptoms of being only able to drive on 3rd gear and hard shift on reverse. It’s giving me code P0753. Should I start by replacing the TCM first before checking anything else?

[@car-u-fix-it8070]

check the solenoid harness first....its below the air cleaner box....unclip it....carefully....spray crc electrical cleaner...dab some dielectric grease on connector....inside where prongs go..re-connect....SECONDLY ...replace A & B solenoids...as the kit comes with both....ebay purchase....IF PROBLEM PERSISTS.....ITS PROBABLY TCM...$450.....OR MORE.....

[@saravykhuon5401]

Anthony Igania hi did you change tcm regarding that code? Thanks

[@anthonyigania8465]

Saravy Khuon yeah bro, it fixed my problem! I changed it about a month ago and my mazda 3 has been driving fine since.

[@saravykhuon5401]

Anthony Igania thanks I’m ordering tcm now

[@Miles-mn2ld]

What are the symptoms? I dont know if the transmission is bad or the solenoid or tcm or,transmission range sensor

[@car-u-fix-it8070]

symptoms: no reverse or hard shift into reverse.....no gear indicator on manual mode.......revs up before going into 3rd or clunks into 3rd gear....I had multiple issues.......TCM bad and transmission speed sensors (2) were bad.....later developed another problem.......rev up high into 4th gear....replaced vehicle speed sensor and fixed problem

[@Miles-mn2ld]

@@car-u-fix-it8070 - thanks for responding, I'm at the mechanic shop, And they are saying its an internal transmissiom failure. 2016 ford fusion se, but autozone did not pull those codes on their scanner. Only,electrical, mechanic said the failure of the,transmission is causing those,codes. Is that true? Can it do that? They also said they had a code that said,internal transmission failure but autozone did not, does such a code even exist? Also, the last day I had the car I noticed the radiator fan was not spinning. I investaged why this could be and apparently the radiator fan is powered by the tcm which leads me further to suspect that tcm is bad

[@Miles-mn2ld]

Also man I had all the same symptoms as you the day before it finally quit and would no longer go into any gear fully or well, no hard clunks but hard shifts, maybe 3 in the last 7 month's. What do I do here? Seriously, at the shop and they got a transmission ready to,go,in for 2400 dollars

[@Miles-mn2ld]

PO712 - failed transmission fluid temp sensor/ PO707 - defective transmission range sensor/ PO PO 760 - shorted solenoid 3 Are the codes from the parts store

[@Miles-mn2ld]

The PO 760 code said "shift solenoid 3 circuit condition. Explanation, ECM energized solenoid and detected an open or shoshortedcondition probable cause 1) an opem or short solenoid 2)open or shorted circuit condition. Also too i keep having to jump start once it could no longer engage gears. Car does make a whiney high pitched sound when giving gas in its current condition. Transmission related but did your car also make this noise or sound kind of like a wind up toy car on colder days

Hello, I cant find any info about a 2005 Mazda 3 TCM. Do you know if it has one & where its located cuz I seen one video for 2005 Mazda 6 & theres was near the brake pedal not under the hood but I cant find any info at all for mine. Also when searching for the part online they all start at 2006 & up no 2005 TCMs hmmm ???

Hi Holly, well from what Ive gathered, you dont have a separate TCM like our Mazda 5 do....it is integrated with the PCM....so its cheaper to buy and easier to replace.....i think its inside the car or next to battery......but please call your local mazda dealer and ask to speak to parts departmrnt and just ask the where is it and how much....then order online.....
