AUTOMATIC TRANSMISSION DISPLAYS UNACCEPTABLE LATENCY DURING DOWNSHIFTS AND UNPREDICTABLE TRANSMISSION RESPONSE TO THROTTLE INPUTS . THIS RESULTS IN UNPREDICTABLE VEHICLE BEHAVIOR, ESPECIALLY DURING FREEWAY MERGES OR OTHER SITUATIONS WHERE A MODERATE AMOUNT OF ENGINE POWER IS REQUIRED. THIS IS AN ONGOING, CONSTANT PROBLEM THAT I BELIEVE IS RELATED TO POOR PROGRAMMING OF THE ENGINE CONTROL MODULE AND TRANSMISSION CONTROL MODULE. *TR

THE AUTOMATIC TRANSMISSION EXHIBITS DIFFERENT TENDENCIES WHEN TRYING TO ACCELERATE. THIS LEADS TO UNPREDICTABLE VEHICLE RESPONSE. IN ONE PARTICULAR OCCASION I WAS ATTEMPTING TO MERGE INTO TRAFFIC AND ACCELERATED.

THIS IS AN EVERYDAY PROBLEM AND RUINS THE EXPERIENCE OF THE CAR. *TR
