Tranny issue after reflash update

When my car was new I experienced the throttle lag at low rpms which was due to the Fly by wire control of the throttles not giving you full throttle when you floored you car at certain rpms. So I had the reflash of the ECU to help with this. This did help the lower rpm power (still not enough for me) but then I started to have a problem with the tranny. In auto mode in sixth gear going down the road, when I would hit a slight rise requiring just a tiny increase in the gas pedel to keep my speed up, the tranny would start this stuttering. Where it felt like it was going in and out of gear rapidly until either I gave it more gas, put the tranny in manual mode or crested the hill and eased off the throttle.

When my car went in for its 7,500 mile check today I bitched about this to the service department. The mechanic says that there is another new TCU reflash to deal with tranny issues. He could not replicate my problem as there are no hills like the ones I have the problem on but he wants me to call if it is still doing the shutter thing so he can contact Mazdas Tech Desk for further assistance. Since my wife dropped off the car I will no more when she returns.

But there is a new Transmission Control Unit reflash from Mazda now availble.

Yes, the reflash of the TCU did the trick.

Smoother shifting. Hunting is gone (cabpatch)
