Quizplus · Accepted Answer

Technician A is correct that some transmission/transaxle computers may require a relearn procedure after a battery disconnect. This is because the computer may lose its stored adaptive memory, which may result in poor shift quality. 
Technician B is also correct that some computers memorize operation patterns to optimize driveability and performance. This is because the computer can adjust its parameters based on the specific driving habits of the driver, resulting in better performance and fuel economy.
