During the road test, the transmission should be
operated in all possible modes and its operation noted.
Check for proper gear engagement as the selector lever
is moved to each gear position, including park. There
should be no hesitation or roughness as the gears are
engaging. Check for proper operation in all forward ranges,
especially the upshifts and converter clutch engagement
during light throttle operation. these shifts should be
smooth and positive and occur at the correct speeds,
these same shifts should feel firmer under medium to
heavy throttle pressures. Transmissions equipped with a
torque converter clutch should be brought to the
specified apply speed and their engagement noted. Again,
record the operation of the transmission in these different
modes in your notebook or on the diagnostic chart.
