My 2010 Mazda 3 was giving me a hard kick when shifting gears. Would do the same when putting in reverse from the parked position. AT and engine light were coming on upon feeling the car jerk.
TCM Removal
- Remove battery box and battery (3-6 bolts). May need to clip plastic tie holding cords.
- TCM is beneath the battery box toward the back. Remove three bolts holding TCM down.
TCM Replacement
- It is recommended that when you replace with the new TCM to mount it toward the drivers seat where the break lines are (zip-ties, etc.)
- Reinsert battery box and battery and you should be good to go!
You can either send the old TCM to UpFix for repair or have them send you a new one right way - you can receive a $300 refund if you send in the old one. This is what I chose since the repair is time sensitive in my case.

Hint: You don't actually need to remove battery and battery box. I was able to reach and remove the three TCM mounting bolts by lying down on the engine.

I went through the teardown process without too much surprise. It took me about 40 minutes. It could be faster if I was anxious. But after seeing the video and knowing what it takes, I was more relaxed to enjoy the process. I was actually thinking about going under the engine to take out the TCM. But standing on the ground is certainly more enjoyable.
After reading some reviews on both options, mail & repair mine or buy a rebuilt one and return the core, I decided to ship mine in for repair. My main decision point is that I don't want to add more complication in dealing with a different TCM.
A little ahead of myself, I am not sure I will follow the recommended steps by mounting the repaired TCM on the brake lines to avoid heat. For one, the TCM is design/built for the specs including heat protection. Two, I don't want to introduce any unintended consequences by breaking other parts in long term durability. But this is only the thought for the moment, I can make a decision when I receive my repaired part.
Some people complained about slow FEDEX shipping. Me too. But then I realized it is only that I set my expectation wrong. FEDEX only says two-day shipping, not two-day delivery. This trick has been used everywhere from those online orders. But only this time I understood it the first hand. I shipped mine on a Thursday morning and it was delivered in the next Monday morning. Now Tuesday morning, I am waiting for UpFix to contact me for the repair.
Updates: I received my repaired part on the 15th day from the day I dropped off the broken unit to FedEx. I installed it without any issue. I decided to attach the unit to the brake lines using 3 zip-ties. All the warning lights were gone and the car drove well as it should be. I only test drove it 1.4 miles. The total cost had several changes. First the repair price increased $40 without an explanation. I then worked on this posting to be qualified for a 50% discount. I emailed the customer service to cash in the discount. I paid when Upfix notified me about the repair completion. Immediately after I paid, the part was shipped. Overall, I have had a good experience with Upfix. The process was stated clearly. The Customer Service was prompt and helpful. Other than the initial repair price increase, there was no more surprise. I generally will recommend this to a friend or anyone, unless the repair doesn't last.
