2010 Mazda 3 TCM Replacement - The ICE Car is Dying

Why the era of the Internal Combustion Engine I.C.E car is coming to an end.

[@bobsoft]

The problem is the heating and cooling of the TCM. That causes circuit board flex and cracking of the solder joints. Move the TCM to the firewall so it does not get as hot as it would sitting on the hot transmission!

What did you do with the old one? Sell it?

[@gavinpowell3107]

This should be a really though why did they place the tcm on too of tranny under battery is why they heat up and go bad

[@angelrios3791]

What size wrench you used in dealing with the same problem I can’t get it off

[@deathoftheautomobile]

see if 10mm wrench is a snug fit?

[@missycolleen]

How is your car doing now? Where did you get your module?

[@deathoftheautomobile]

its doing well, need to replace cv axles very soon and i got the TCM off of ebay

[@missycolleen]

@@deathoftheautomobile I also got one off ebay and it s been in for two weeks, no problems. Your video really helped me out. Haven t really put it to a test on l.a. fwys or the mountains yet but it shifts well around my city

[@deathoftheautomobile]

@@missycolleen yea like i said in the video... i think... i was getting the AT light and i brought it in to the dealership for diagnostic and it cost like 230$ for them to tell me i needed a new tcm and they were going to charge another 1200 to replace it hahaha.... got my tcm for 200-250

[@missycolleen]

[@keishawnmcdonald]

Did u need to reprogram?

[@deathoftheautomobile]

nope

[@kyzor-sosay6087]

Up fix,you can send your TCM to up fix.They will refurbish the TCM, no programming required.

[@michaelkelly3501]

You don't need to replace the TCM, just reset it.

[@justinaparsell5897]

How do you reset it

[@deathoftheautomobile]

i am sure the stealership would have tried that lol

[@gavinpowell3107]

Weirdly enough I have 260 000k on my mazda and my Tcm didn't go bad until I was at 256 000, been driving it since .. if you pull over and turn vehicle on and off my light will sometimes turn off and vehicle run good again.. don't be fooled if you have any problem with electric car you not going to be able to fix a damn thing...

[@javiervelez892]

Right now electric cars can be super expensive to fix. Everything breaks down eventually

[@butWhyDad]

You probably live in a colder climate

[@allenbeal7747]

Electric cars are EVEN worse
