My tranny worksok but when going 40 mph and you want to take off faster it wont dowshift.
we plug it to comp and nothing comes out as a problem, Also I replaced oxigen sensor, catalityc convertor ceaned airflow and other engine services the car is still to slow like no power. Now i tooked to a transmission guy and he said tranny is ok so why is it not dowshifting and feels kind a heavy? what do i do?
