Source note on shared footage
We have a massive and growing video library, but we don't have everything...yet.
Car companies often use the same engines in different cars. They also slightly alter the styling and sell the same car by two different names (amongst other tricks to help offset development costs).
Our system selects the most applicable video for your car based, in part, on these characteristics. The video displayed may not look exactly like your car, but may be relevant enough for you to get a good idea how to do it.

我们有一个庞大且不断增长的视频资料库，但还没有全部内容……
汽车制造商经常在不同车型中使用相同的发动机。 它们还略微调整了外观设计，并以两个不同的名称销售同一款车（以及其他一些技巧，以帮助抵消开发成本）。
我们的系统会根据这些特性，部分地选择最适合您车辆的视频。 视频中显示的内容可能与您的车辆外观不完全相同，但可能足够相关，让您了解如何操作。
Procedure notes
The engine in your 1990 GMC G3500 should be running when you perform a transmission fluid level check, otherwise it will be inaccurate. The video above shows where the transmission fluid dipstick or the transmission fluid check plug is located in your G3500 and how to check the transmission fluid level. Your G3500 will have either a transmission dipstick or a check or fill plug to perform a transmission fluid check. The transmission dipstick will typically be in the engine bay or on top or even the side of your G3500 transmission. The transmission check plug will typically be on the bottom or the side of the transmission and may also be next to the axle. If the transmission fluid level in your G3500 is low, you need to add transmission fluid through the dipstick tube or the check plug hole. When adding transmission fluid to your G3500, be sure to add it slowly as it will fill up quickly and is difficult to remove excess fluid if you overfill.
If you are having problems with the transmission in your G3500, such as clunky shifting or hesitation, check the fluid level first - it is amazing how many drivers pay thousands of dollars for transmission work when a half quart of transmission fluid would have fixed the problem.

在进行变速箱油液位检查时，您的 1990 GMC G3500 发动机应处于运行状态，否则检测结果将不准确。 上述视频展示了您的 G3500 车型中变速箱油尺或变速箱油检查孔的位置，以及如何检查变速箱油液位。 您的 G3500 车型将配备一个变速箱油尺或一个检查/加注螺塞，用于检查变速箱油。 传动轴油尺通常位于发动机舱内，或位于您的 G3500 传动系统顶部或侧面。 变速箱检查孔通常位于变速箱的底部或侧面，也可能位于传动轴附近。 如果您的 G3500 变速箱油液位偏低，需要通过油尺孔或检查孔加注变速箱油。 在为您的 G3500 添加变速箱油时，请务必缓慢添加，因为油会很快充满，且如果加得过多，很难清除多余的油。
如果你在你的 G3500 变速箱上遇到换挡不顺畅或迟滞等问题，请先检查变速箱油位——事实上，很多车主花费数千美元进行变速箱维修，其实只需加注半夸脱变速箱油就能解决。
