be checked when the temperature of the
fluid is between 35° and 45°. The reading
obtained will be incorrect if the fluid is
outside this temperature range.
5.Start engine, move selector lever from 'P'
through all gear positions, pausing in each gear
position for 2-3 seconds and return to 'P'
position.
6.Clean area around level plug.
