The PCM updates are seperate from the TCM updates. Latest WDS version is 32_4...but many dealers won't have that. (It seems to be a difficult task for some dealers to maintain their latest software versions)
I also have been having problems with Shift Shock in my 2003 Mazda 6. It shifts erratically intermittently and also does the hard shift between 1st and 2nd gears during warm up especially but sometimes in other gears also. In using the sportronic mode, it always does it between 1st and 2nd. I'm taking my car in again tomorrow. I also wrote Madza USA but got a nebulous response from them.
With engine in the fully warm condition, and during light throttle acceleration, 1-2 shift shock may be felt at certain times. Also, as 4-3 downshift shock maybe experienced during braking conditions. A revised TCM calibration is available to improve this concern.
1. Using WDS B30 or later software, reprogram the TCM to the latest calibration. Filename SW-AJ58TG000
TCM cal. P/N AJ58-G
2. Remember to erase all DTC's after reprogramming procedure.
3. Road test vehicle to relearn KAM and verify no MIL illumination occurs
Call your dealer and verify with a service advisor or manager, that they have AT LEAST WDS version B30. If they don't, your visit will be futile. If your normal dealer is that behind, I'd find another (they should be at B32_4)
ok got another one...what if on manual mode 3-4 shift you get to 4th but someone cuts you off and you let off gas and hit brakes for a slight 6-8 mph loss should the tranny leave 4th and slam into hi revving 3rd?
The TCM update addresses multiple shift points in the ATX. It may solve more issues then the shift shock. If you haven't gotten it yet, I'd recommend you do so.

does the computer update concern the 2.3 liter auto tranny Mazda 3 GT as well, since it's the same engine, I dont know, is the tranny the same as well?
