i bought a refurbed tcm for a 2011 mazda 3 2.0l engine as the existing one was giving the classic symptoms of a bad tcm, at and traction light on,
that was in may 2022 and now the refurbed one is acting up.
i did not give back my old one as they requested because they were only giving back a few dollars, but i resoldered / reflowed specific areas of the tcm circuit board sometime ago and now i can test to see if i did actually fix it.
more to the story as you will see especially with the now bad refurbed tcm
