Car “bucks” for now reason, especially when accelerating after a stop. Mechanic called it a transmission problem through a diagnostic, fixed with new parts, and less than a week later, the same problem, but worse this time!

Since it is worse after repair, whatever was repaired likely involved in the cause. For better results here, suggest to post more info about the transmission repair.

As far as my own experience with that symptom, worst case caused by a problematic idle air control gadget on my Corolla. Minor case caused by fuel injector problem.

Suggest to post engine number and type of transmission as well. Engine number usually on underside of hood sticker.
