Last Updated on January 13, 2023 by Robert Wilson

Kymco Mxu 300 transmission problems are a common issue with this vehicle. The most common problem is that the gears will slip out of place, causing the vehicle to jerk or stall.

If you own a Kymco MXU 300, you may have experienced transmission problems. The good news is that there are some things you can do to fix the problem.

First, check the oil level in the transmission. If it’s low, add more oil until it reaches the full line on the dipstick.

Next, check the condition of the transmission fluid. If it’s dirty or burnt, replace it with fresh fluid.

If those steps don’t fix the problem, then you may need to replace some of the parts in your transmission. This includes the clutch, gears, and bearings.

You can find replacement parts at most auto parts stores or online retailers.

If you’re still having trouble after replacing some of the parts in your transmission, then take it to a mechanic or dealer for further diagnosis and repairs.

Common Kymco Mxu 300 Transmission Problems

The Kymco MXU 300 is a popular ATV that has been on the market for several years. It’s a reliable machine that is known for being tough and durable.

However, like all machines, it isn’t perfect and there are some common problems that owners report.

One of the most common issues is with the engine. Some owners have reported that their engines seize up or fail after just a few hours of use.

This seems to be more common in cold weather, so it’s important to take extra care of your MXU 300 if you live in an area with colder temperatures.

If you do have this problem, it’s important to take it to a qualified mechanic as soon as possible so they can diagnose and fix the issue.

Another common problem with the MXU 300 is electrical issues. Many owners have reported having problems with the headlights flickering or going out entirely while riding.

Other electrical issues include problems with the starter button, kill switch, and turn signals. Again, these are all safety-related items so it’s important to get them fixed promptly if you’re experiencing any issues.

Lastly, some owners have also reported problems with leaking fluids from the ATV. This is usually oil or coolant, and can be quite messy (and dangerous) if not dealt with quickly.

If you notice any leaks on your MXU 300 be sure to clean them up immediately and check for any damage that may have caused them.

These are just some of the most commonly reported problems with the Kymco MXU 300 ATV.
