Transmission Warm-up
使机油逐渐预热的情况下，轴承部件能保持最佳的工作状态。 冷起动时高速可能缩短轴承部件的耐久性。 在预热过程中，变速箱上的电子控制系统在一定的冷油温度范围会限制可用的变速箱档位。 如果温度低于 −23
°C (−10 °F)，使发动机预热大约 20 分钟。
变速箱机油加热器
如果环境温度为 -23° C（-10° F），变速箱用户或操作员可以选择安装变速箱机油加热器。 加热器有助于在低温条件下起动车辆，并降低车辆进入工作状态所需的预热时间。 CX31 在变矩器壳体下方有一个 SAE J1926 #16 直螺纹 "O"形圈集油槽加热器端口。 一般而言，供应商会建议每夸脱集油槽机油使用 8 到 10 瓦加热功率。 市售加热器（带或不带节温器）有与 CX31变速箱兼容的 150、300 和 500 瓦容量可供选择。
