为了让变速箱经久耐用e8d152788e16a9cd0acc174b073d75795635fb3c,工程师在研发时就得考虑到各种极端状况ef823fdbd538a9889ffcb4d7de7a758c0c632fb1,还进行了严格测试396314873ad7d6e1a6517578a255dd8f。假如汽车挂P挡停在斜坡上b7748152b5e68f9fdad8b40bf0bdb14a,齿轮和棘爪会越咬越紧4855e83e57c20cfe02e5b1fe0ed4f2700b473d80,这时再启动车辆MDAwMDAwMDAwMHp9js6D3LiUjnp_q7GggaC9tcui,挂挡就会相对费劲些JjVhMzU0ZDMzMmMyMjg=,不过这点摩擦力也不足以伤害齿轮JTVhMzU0ZDMzMmRlZGQ=JTVhMzU0ZDMzMjhkMTk=
