I have an 8 speed transmission that stalls upon acceleration lurches and surges when trying to shift gears. When coming to a stop lunges forward due to a shift in the transmission. I have taken to the dealer multiple times and express my concerns they finally replaced torque converter and flushed transmission now they state that it is operating correctly.
