low gear

• The overall shift schedule with tc + amt ( automatic mechanical transmission ) is worked out , which meets both the requirements of off - mad performance and maneuverability at low gears as well as fuel economy at high gears on better road
  制定的液力变矩器和机械自动变速器的综合换挡规律，既可满足低挡位越野性能和机动性能的要求，又可在良好路面、高挡位行驶时满足燃油经济性的要求。
