Rebuilt TCM, still not working?   23 Relevance 3 years ago ETinLV TCM Transmission Control Module
  Hello!I received a remanufactured tcm from Upfix for an 08 mazda 3. After installing, I am getting a different error code and the transmission is stuck in limp mode. This is not the same problem I had before. I have done everything I can think of, and I believe the remanufactured tcm may be bad. Here is the long version:Originally the car would intermittently throw code p0791 and p0720 and unexpectedly downshift, exclusively on hot days. All three sensors were changed, transmission fluid and filter replaced mutiple times. But the problem persisted. Which le ...
2010 Mazda 3 TCM repair needed   13 Relevance 2 years ago Luis Rivas TCM Transmission Control Module
  A technical query pertaining to tcm on a 2010 mazda 3.Car was taken in for repair. needed a tcm in the first place. Instead of replacing the tcm, the shop replaced the transmission. They've returned and asked for an extra $1600 to replace the tcm.Will extra calibration be required if I use your service and send the old one in if I'm installing it on a new transmission? The tcm is the only component left for the new transmission to function. Attachment : 2010 mazda 3 tcm repair needed.png

Repaired tcm issues   10 Relevance 2 years ago Jdhahn1004 TCM Transmission Control Module
  Hi, You guys repaired a tcm for me last week, for my 2008 mazda 3. I had a CEL light, AT light, and TCS light all come on, with multiple codes and very rough shifting into reverse and drive. After some research I decided sending the tcm to you guys for repair would be the best option. After receiving it back, I installed it and relocated it to the brake lines, as you recommend. With everything back together, I started the car and the CEL light and TCS light are now off, but the AT light remains on and the hard shifting problem remains. Before installing, ...
Mazda 3 2010 TCM   10 Relevance 4 years ago GLENN BOOTH TCM Transmission Control Module
  Hello, I have this issue with my mazda 3 2010 tcm where there’s a hard kick and car goes into safe mode(AT light turns on), check engine light is always on by the way. Another problem is that I’m quite far away from you guys so the postage cost through FedEx reaches up to 150€, the question is, what I should do to fix this problem, buy a new one which I can’t find, try to fix it at local car electrician or send it to you? Sending faulty codes and a picture of tcm itself. Thanks.nother question, can I install a tcm which has different code on it?Or should onl ...

  ... link for Help\Tips. 2, After your suggestion in post #2 "try the hard battery reset first (guide attached) with both negative and positive terminals constantly touching for 30-40min and the battery removed", the problem is still persisted since Dec 7, 2022. 3, I took the car to a mazda dealer & paid $179 + tax for diagnosis fee.

08 Mazda cx9 replacement transmission out of a 09   0 Relevance 5 months ago Violeta TCM Transmission Control Module
  My mechanic installed a replacement transmission in my 08 cx9. Everything works fine but sometimes the car doesn't want to shut off and some of the dash lights don't turn on. Does the tcm need to be reprogrammed for my specific vin? The replacement transmission came out of a 09. I don't have the original tcm

RE: Remove TCM out of 2006 Mazda 3 2.3L (VIN JM1BK1434...)   0 Relevance 2 years ago Serge - UpFix Team TCM Transmission Control Module
  We apologize that you're still experiencing issues with the rebuilt tcm. This unit should essentially be plug and play with no issues. When did the issues re-appear and what codes specifically are you getting now? Have you tried to scan the QR code at the bottom portion of the packing slip? This will bring you to a link for Help\Tips. Please try the hard battery reset first (guide attached) with both negative and positive terminals constantly touching for 30-40min and the battery removed. If you have dark or dirty transmission fluid I recommend replacing it with fresh fluid and a new filter. Check wiring, plugs, and pins. Make sure they are free from debris, dirt, grease/oil, and battery acid. Mount the tcm to the brake lines. The heat from the transmission and the engine is usually the main culprit for the initial failure. Check your speed sensor and your oil pressure switch to the transmission as well. Once you have completed the above steps, re-scan the car and let us know which codes came back. That'll help us know exactly what is causing the issues. Below I have both guides to assist. I highly recommend that you follow the guides step by step for the best results. If you followed the re-installation procedure and already tried the hard battery reset to the letter we can take another look under warranty or issue you a refund. Let us know the results.
