My old Mazda has served me well with 350,000 KM's but my curiosity has been piqued with this issue. The transmission did a hard downshift and lost reverse. No fluid leaks, no grinding or shudders. Shortly after this it went into limp mode and I managed to get it to a service station. On the way to the station the AT light fired up.
The service station tested it and found no codes the next day, checked the fluids and called me to come get it. I took it for a 20KM test drive and there issues had disappeared! No AT light, no CEL, no codes.
Later in the day I returned to actually take the vehicle home. Now it only had reverse and no forward gears. I left the vehicle were it was (not like I had much of a choice). A couple days later I was called to pick the vehicle up. No codes, no CEL. Drove it home (15KM) and was told nothing further could be done because there were no further codes.
Next day, no forward or reverse but plenty of neutral. Now, no forward or reverse or neutral. I can move the shifter (lights change from RDNM1/M2) but now is in park and cannot be moved. No codes, no leaks, no CEL. Just thought I would share this (bizarre event, at least to me) situation with the forum.
