If you drive a box truck, you most likely aren’t using it for personal reasons. Therefore, you need to make sure that it’s functioning at all times. With this in mind, here are five signs your box truck transmission is failing.

The Check Engine Light Is On

When your check engine light is on, it could be an indication that there is something wrong with the transmission. Many problems can cause your check engine light to turn on, including transmission troubles, so don’t hesitate to get your truck looked at when the light comes on.

Transmission Fluid Is Leaking

One of the most obvious signs that your transmission might be failing is if your truck is leaking transmission fluid. Since most box trucks have an automatic transmission, having adequate fluid is vital for your truck’s ability shift gears.

When your truck is working properly, the transmission fluid will be clear, red, and have a sweet aroma. However, if your fluid appears darker or smells burnt, it might signify that you should replace your fluid. Your transmission fluid will burn if your transmission overheats, so if your transmission isn’t lubricated after you replace your fluid repeatedly, it could mean that it’s leaking somewhere.

Your Transmission Is Loud

If your truck is excessively loud, it could mean your transmission is in serious trouble. Although replacing the transmission fluid should fix the problem, if fluid is leaking, then it could cause your transmission to receive serious damage. Finding a dedicated Isuzu truck repair service is critical to maintaining your vehicle so that it doesn’t sustain damage.

It Won’t Shift Gears

If your transmission refuses to shift to the proper gear, this is a telltale sign that your transmission is failing. For automatic transmissions, this will usually occur when you’re trying to shift into Park or Drive. Some of the common causes of this phenomenon are lack of transmission fluid, incorrect fluid viscosity, or improper adjustments of the clutch linkage or shift cables.

You Feel Grinding When You Shift Gears

Finally, you should be concerned if your transmission grinds or shakes violently when you shift gears. A functional transmission will have a smooth transition from gear to gear, so if yours operates differently, you should take your truck to a repair mechanic right away.

Overall, maintaining your truck will not only help you be more productive at work, but it will also keep you safe.
