Technician B is correct because the Eaton HLA (Hydraulic Launch Assist) system indeed uses a reversible hydraulic piston pump/motor to store energy and assist in vehicle propulsion. Technician A's statement about the HLA accumulator being loaded with pressures up to 5,000 psi is incorrect; typical systems operate at lower pressures.
