Mazda 3 Transmission Control Module Change, Code U0101

[@aaronartale]

I've repaired 2 of these by resoldering the circuit board. It seems like the common point of failure is the through-hole connector solder joints. I resoldered the whole board anyways, but the through holes had visible fracturing in the solder joints. Get them off the transmission, the heat and vibration is the problem. The connector pins coming out of the circuit board are long and bent 90 degrees, so they'll vibrate like a tuning fork and eventually the solder joint cracks. All you gotta do is peel off the epoxy at the base of the connector to get at the through-hole pins. Touch them with a soldering iron so all the solder completely re-wets. Use LOTS of flux, then clean it off with alcohol when you're done. Replace epoxy and remount off the transmission

[@Karen-ur6mm]

Can you make a video please? I'm working on 3rd replacement in 3.5 years and its getting old

[@HuskerRed11]

That's good to know they can be repaired by yourself. Are your repair jobs still holding up on the TCM's?

[@marstechnicians]

Just did this to my TCM and it worked, no more “Lost Communication With TCM”. There’s 39 pins that you need heat up with soldering iron and add a little more solder. Removing the silicone took a while but it’s not much that needs to be removed.

[@schtoopid]

How did you get the epoxy off the board?

[@marstechnicians]

@@schtoopid I used a razor blade and a small flat head screwdriver. Just be patient, it takes a while. Alcohol seemed to help a little.

Followed this tutorial and completely fixed my TCM problem. It saved me over $3000 (new TCM and tool box included) by doing it myself compared to my mechanic’s quote. I’ve never done more than change a tire but this was super easy to follow along with. Thank you so much!

I really appreciate your clear instructions for removing the battery box, etc. That was the most daunting part for me, as i was afraid I'd end up breaking something that wasn't already broken.

[@Zak003]

This saved me $2500 easy. Got a quote from the dealership who wanted $3000 (if) they didn’t find problems with the transmission or need to program the TCM. They also quoted me $800 for the TCM alone. I found a dealership online who sent one my way for $550 including expedited shipping. No more than 1.5 hours of work (mostly just swearing at the battery box) and the car was as good as new. I can’t thank you enough for this walkthrough.

[@davebullard4772]

@@Zak003 can you send me a link to where you purchased yours. I've heard of people ordering them and not being programmed correctly or not at all. I've been quoted the same at Mazda so looking to save a few bucks and with this video doesn't seem like it's out my scope of ability. Another question did you put the TCM back in the stock area or did you place somewhere else such as the firewall to keep away from heat of the exhaust that is from what I've read is damaging the TCMs Thanks Dave

[@bobsoft]

FYI- The transmission is a hot zone and causes the TCM board to get hot and flex causing problems with solder joints on the TCM PCB. You want to put the replaced/fixed TCM on the firewall. Attach it with zip ties to the brake lines on the firewall. Use a pad of rubber in between to isolate the brake lines. I have a 2007 Mazda 3 mounted that way and its still running with the original TCM.

[@davebullard4772]

Yeah everything I read about TCMs in mazda 3s like you said in a hot zone. Thanks for mentioning this I'm trying to find a place to buy one as I was watching video that's programmed I see price all over the board

[@Alobster1]

It's a good idea to not put the tcm back where it was. This problem is caused due to solder joints cracking from thermal stress. It gets too hot where it sits. Put it up on the back firewall instead.

I don't think the year matters as long as you get the TCM for the same transmission. For example 2011 had a 5sp trans and the 2012+ had skyactiv and 6sp trans.

@@jamiehamel9669 Did replacing the TCM work?

[@davidazatyan7789]

any updates? Did it fix the problem? I got the same problem but $500 dollar is too much for me. How can I find the TCM for cheaper price?

Does the New TCM have to be programmed?

[@FaRKle0079]

The TCM I bought from the dealer was plug and play. No programming required.

[@robersonpetitfrere5479]

I have this problems, somebody can help me? 😢😢😢

[@bobsoft]

Go to an auto wrecker for replacement or send it out for repairs.

[@juansalguero7000]

after you buy the TCM don't you have to have it programed before installing the TCM

[@FaRKle0079]

No programming was required before installing. It was plug and play for me.

7:40 - why Mitsubishi manufactured?

[@FaRKle0079]

Mitsubishi (a conglomerate with many different divisions) OEMs electronic modules for anybody in the auto industry. Same reason why BMW, VW, Porsche, and Mercedes can all be found with Bosch ECUs controlling their engines.

[@javorismorgan1915]

Where did u buy the module

[@FaRKle0079]

We bought it from the Mazda dealership.

I’m getting my Mazda currently fixed for a replacement TSM but I was told “the wiring is hard and they couldn’t do it” and they ordered the part but I was told “the one we ordered wasn’t correct” “we needed to buy the one with your car the one they sell at dealerships that usally only come with a new transmission” and said they’d call me back... does that sound like a thing... or would there be two different model TCM? Apparently my Mazda has to different versions on that year and that would be the issue

[@FaRKle0079]

The wiring being difficult doesn't really make sense to me. The wiring should be in connector housings, so there's no individual wires to deal with. Dealers should be able to get the right TCM for your vehicle with the VIN number. I suppose there could've been a year where they transitioned from the 5sp to 6sp auto, but then it should still just be a matter of getting the right TCM and plugging it in. I haven't heard of dealers only selling the TCM if you buy a new transmission.

@@FaRKle0079 Thank you for this detailed response I will keep you posted if you don't mind as with covid and a recent death in my family I'm very anxious due to this situation and the possibility of it going from a $600 repair to a entire transmission being 2000$ +
