  ... to use an extension on your socket wrench as it's a bit tight to work on there. Once that is removed (or before is fine), you will want to lift the lift for the connectors in your battery compartment. These can be removed easily with a screwdriver being driven between the white latch and the holder, applying a slight twist to the screwdriver while lifting up on the white latch. Detach both connectors and put them to the side. To remove the battery holder, you may want to remove the front plastic plate of the holder. There are a handful of cables that m ...

  Thank you for reaching out. Step 3 should've been to contact us first before going to the dealer to spend money on diagnostics. if the TS didn't help, we can take another look under warranty and see what the issue is.

  ... 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.

RE: Remove TCM out of 2006 Mazda 3 2.3L (VIN JM1BK1434...)   0 Relevance 3 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.
