5 Warning Signs for your Hyster Forklift Transmission

Worried about your Hyster forklift transmissions or wondering about the needing service warning signs? Glad you found this article, it’s certainly important to know. You don’t have to be a Hyster forklift service person to know when your machine needs some maintenance. Being familiar with the sounds, normal noises, and irregular behavior of your forklift will save you tons of money, as well as keep your machine running for a long time. 

Let’s look at the four signs your Hyster forklift transmission needs service or replacement.

Difficulty with gear shifts

One big sign your Hyster forklift transmission is begging to be serviced is difficulty changing gears. A transmission in working order will shift fears seamlessly rather than a delayed engagement. If it takes a bit to shift from forward to reverse, the gear is struggling or is having difficulty picking up momentum after a gear shift, then you may want to take a look at your transmission.

Now, difficulty in shifting gears doesn’t always mean a transmission problem. There could be other issues at play here. No matter what is the culprit, if your shifting gears are becoming problematic then the longer you wait to find out what the problem is, the more damage will be done to your Hyster forklift.


Some noise for any machine is normal. There are a lot of bolts and turning gears, after all. What isn’t normal is sputtering every time you shift gears in your Hyster forklift. Other noises that should concern you are rattles, clangs, hisses, anything that sounds like metal on metal grinding. These are all signs to look at your Hyster forklift transmission.

Noises can happen when using a Hyster forklift, or any machine for that matter. How this is a warning sign for your transmission is that they generally happen when you’re changing gears. Another noise to listen out for is when your Hyster forklift is in neutral, a bumping sound usually means it’s time to call a service person for your Hyster forklift transmission.


Changing direction when driving should be as smooth as shifting gears and, if it isn’t, could be for a lot of reasons. You want to watch out for sudden judders when changing direction while driving. It’s often a sign that the Hyster forklift transmission is wearing or close to worn out. The machine shouldn’t be jittering suddenly, especially when changing direction. Take it to a service person to get it checked out quickly.

Transmission Fluid

Probably the clearest sign your Hyster forklift transmission needs help is the transmission fluid. If you’re running into some of the issues mentioned above, take a look at the fluid. It should be a bright pink or less than bright pink if it’s been a bit since the fluid has been changed. If it’s dark, thick, bits of metal in it, or has a burning smell then you need to get it changes as soon as possible.

Bad fluid transmission can damage a lot if left filthy. You want to make an appointment to get your Hyster forklift transmission services right away, especially if you find bits of metal and burning smell.

The Warning Light

The last tip for knowing when to take your Hyster forklift transmission is the engine light. May seem counterintuitive but, the engine service light doesn’t always mean it’s the engine that needs to be serviced. If you see that light on, and you’re experiencing some of the other problems on this list, take your Hyster forklift in to be checked out. 

The only time that light should be ignored is when it’s known to turn on and off at random. Even then, don’t ignore it. That means something is wrong with the wiring and you want your warning system intact.
