The car started to stall, hesitate and even stop completely for no apparent reason. The mechanic first recommended a new ECU/TCU which did not help the problem and in the course of duplicating the problem check engine light has come on for the transmission with problems shifting/sticking in a gear and not returning to first gear. My mechanic has stated that there is a known problem with Mazda3 transmission, and I should reach out to Mazda. They indicate there is no recall, but mechanic provided me TSB reference number 0500814 from a service bulletin. The car is a death trap and I have stalled while driving on the streets and freeway so obviously I can't drive the car. The car is still at the mechanics since parts cannot be found. Please help any way possible. Thank you.
