Accumulators in an automatic transmission are being discussed. Technician A says that an accumulator helps progressively apply a clutch or band, eliminating a harsh shift. Technician B says that an accumulator has a piston installed in a bore with a spring, and a gradual increase of fluid pressure is applied against the spring, preventing driveline stress. Who is correct?

B) Technician B
C) Both technicians A and B
D) Neither technicians A nor B
