Kubota RTV 500 transmission problems

In this brief guide, we are going to provide you with the common Kubota RTV 500 transmission problems and what are the solutions to these problems.

Kubota RTV 500 transmissions use primarily hydrostatic transmissions in their ATVs. This transmission works mainly by belt driven on ATVs and by shaft on rotors. However, there are many problems with Kubota RTV 500 transmissions and we’ll tell you how you can solve them.

What are the common problems with Kubota RTV 500 transmissions?

Most of the common problems with Kubota RTV 500 transmission are:

  • Transmission slippage
  • Hydraulic system overheating
  • Hydrostatic Transmission pump failure
  • Transmission overheating
  • Cold hydraulic system malfunction

Why is the Transmission slippage a problem with Kubota RTV 500 transmissions?

Kubota RTV 500 transmission system is not designed to slip and if you are experiencing slippage then it could cause slow response or further damage to the transmission system. So, it is definitely a sign of a problem with the hydrostatic components of the transmission.

What signs are shown by this Kubota RTV 500 transmission problem?

You will be able to hear the transmission slip while driving and this would be a good sign if there is slipping. Also, an error code will be displayed if you use a diagnostic tool.

What is the solution to this Kubota RTV 500 transmission problem?

The solenoids of the two gears might be worn out and need to be replaced. Also, there is a chance that these solenoids might also be broken. Rarely, complete mechanical failure occurs with these transmissions.

Why is the Hydraulic system overheating a problem with Kubota RTV 500 transmissions?

Fluid contamination of Kubota RTV 500 transmissions can cause the system to have temperature issues and overheat. This is another common problem in Kubota RTV 500 transmission and fluids contamination are caused by leaks in the system. 

What signs are shown by this Kubota RTV 500 transmission problem?

Generally when a Kubota RTV 500 transmission overheats an error is shown. This error is not immediately visible on the screen but requires a diagnostic tool to get these actual error codes.

What is the solution to this Kubota RTV 500 transmission problem?

The solenoids of the two gears might be worn out and need to be replaced. Also, there is a chance that these solenoids might also be broken. Rarely, complete mechanical failure occurs with these transmissions.

Why is the Hydrostatic Transmission pump failure a problem with Kubota RTV 500 transmissions?

The Kubota RTV 500 Transmission Oil Pump is generally reliable, but sometimes they lose efficiency very early in life and it’s struggle to produce pressure quickly begins to deteriorate as it ages. This will mainly affect the shifting performance of the vehicle.

What signs are shown by this Kubota RTV 500 transmission problem?

While driving you will surely notice the shifting difficulty and in worst case complete failure for this problem. As this is a shifting failure, only while driving at the set speed and rpm will you notice this problem.

What is the solution to this Kubota RTV 500 transmission problem?

Usually the transmission oil pump is worn out and needs to be replaced to solve this problem. Also in other cases it has been seen that oil pumps can be removed and rebuilt to solve this issue. 

Why is Transmission fluid leakage a problem with Kubota RTV 500 transmissions?

Kubota RTV 500 transmissions are very advanced and leakage proof systems and if anything is leaking out of them then this could cause transmission overheating. It is definitely a sign of a problem which may cause serious trouble for you in the future.

What signs are shown by this Kubota RTV 500 transmission problem?

You would get an error such as P0842 or errors in the similar range which are associated with transmission fluid pressure. If these sensors get a low pressure this will indicate there is not enough fluid and a leakage somewhere in the transmission.

What is the solution to this Kubota RTV 500 transmission problem?

Detecting where the leak is and closing it, is the most obvious solution to fix this sign before it causes mechanical damage to your car. Usually the gaskets or the seals in the transmission are worn out or broken to cause a fluid leak.

Why is the Cold hydraulic system malfunction a problem with Kubota RTV 500 transmissions?

If your Kubota RTV 500 transmission is too cold, it becomes a serious threat to your system. First, the hydraulic fluid becomes thick and unable to reach the pump. In the long run, the hydraulic system will be unable to dissipate heat and damage the transmission.

What signs are shown by this Kubota RTV 500 transmission problem?

You would notice on the sign dashboard if your hydraulic system is too cold to work and needs some preheating to start working. 

What is the solution to this Kubota RTV 500 transmission problem?

You would need to fill some anticoagulant in your transmission fluid to stop it from becoming too thick. Also, if the temperature sensor is detecting a low temperature too frequently then there is a need to visit your mechanic.

How to diagnose these common problems with Kubota RTV 500 transmission precisely?

If you are an experienced driver then you can use common diagnostic tools such as OBD-II immediately and fix those errors. For others, the only way to precisely diagnose these signs is to visit your local mechanic or service station who will have a more accurate diagnostic tool to check these signs. 

How to prevent getting these problems in the first place?

Regular maintenance is an easy way to extend the life of your transmission. Failing to have your transmission serviced on time, will result in catastrophic wear to internal components, which include the hydraulic system which is the heart of the hydrostatic transmission. 

FAQs: Kubota RTV 500 transmission problems

How does a Kubota RTV transmission work?

The Kubota transmission is what they call a “Variable Hydro”. What it essentially means is it operates more like a hydrostatic tractor transmission than a UTV transmission. Pushing the accelerator does increase the engine RPM’s, but it’s not exactly the same experience as the typical CVT transmissions.

How many hours can you get out of a Kubota RTV?

Regularly maintained Kubota tractors should last between 4500-5500 gauged hours. As many tractor owners report using their tractor for only 100-200 hours a year, this can translate into years of use. If you have the time and skill to optimally tend to and care for a Kubota tractor, you have a chance to exceed 10,000 hours.
