Eaton Fuller automatic transmission problems

In this brief guide, we are going to provide you with common problems with Eaton Fuller automatic transmission and what you can do to rectify these problems before they worsen.

Eaton Fuller is an automatic transmission and does not require any manual input to shift gears while driving as most of the cars have automatic transmission. Various sensors and mechatronic systems work in coordination to shift gears automatically. 

Automatic transmissions have a global reputation for quality, reliability and durability. However, there are many problem with automatic transmissions and we’ll tell you why and how you can solve them

What are the common problems with Eaton Fuller automatic transmission?

Some of the most common problems with Eaton Fuller automatic transmission are:

  • Mechatronic malfunction
  • Transmission overheating
  • Shift solenoid failure  
  • Transmission fluid leakage
  • Loud and unusual noises

Why is Mechatronic malfunction a problem with Eaton Fuller  transmissions?

Eaton Fuller transmissions are very advanced but dependent on a lot of mechatronic components. If these mechatronic components fail then Eaton Fuller transmission is unable to function properly and results in poor drive

What are the signs of this problem with the Eaton Fuller transmission?

Error codes appear when the mechatronic sensors fail and in the majority of cases when the cable connecting the sensor to the transmission control unit has come loose.

How to solve this Eaton Fuller transmission problem?

Make sure that the cable is properly connected to the sensor or the sensor itself is working. These are the ways of fixing this malfunction on an Eaton Fuller transmission.

Why is Transmission overheating a problem with Eaton Fuller   transmissions?

Because Eaton Fuller transmission mechanical components tend to get damaged, worn, and malfunction under high heat levels. This results in lower than the acceptable performance from the vehicle and high fuel consumption as well as lowering the life of the gearbox.

What are the signs of this problem with the Eaton Fuller transmission?

Generally when a Eaton Fuller 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.

How to solve this Eaton Fuller transmission problem?

After cooling down the Eaton Fuller transmission check the gearbox oil for its condition. Change it if it is too thick and completely black. Also, check your clutch if it is the problem behind this malfunction.

Why is Shift solenoid failure a problem with Eaton Fuller  transmissions?

Shift solenoid malfunction means there is a problem with the gear shifting. An Eaton Fuller transmission changes gear by directing pressurized transmission fluid to move clutches and bands around. The computer controls all of this with little spring-loaded devices called solenoids.

What are the signs of this problem with the Eaton Fuller transmission?

P0750 is the code that will be shown if there is a shift solenoid malfunction with the Eaton Fuller transmissions. This is a generic code which you will get using OBD-II for your transmission.

How to solve this Eaton Fuller  transmission problem?

Some common solutions are changing the transmission fluid and filter or replacing faulty solenoids. Also you can repair or replace a faulty transmission pump.

Why is Transmission fluid leakage a problem with Eaton Fuller transmissions?

Eaton Fuller 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 are the signs of this problem with the Eaton Fuller transmission?

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.

How to solve this Eaton Fuller 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 Loud and unusual noise a problem with Eaton Fuller transmissions?

These Eaton Fuller transmissions are not manufactured to make such loud and unusual noises and if you are hearing such unpleasant noises while driving then you should check with your mechanic as this might get a serious damping issue.

What are the signs of this problem with the Eaton Fuller transmission?

You will hear these noises while driving and will be very unpleasant to your ears which can be taken as a sign that the transmission is having some problem.

How to solve this Eaton Fuller transmission problem?

Normally this sound means that a component within the assembly needs to be replaced as it might be fractured. The entire assembly from which the sound is coming must be removed and rebuilt to fix this problem.

How to precisely diagnose these common problems in Eaton Fuller transmission?

If you need to precisely diagnose these common problems then you need to use a diagnostic tool which is software based and can be connected to the vehicle electronic system as Eaton Fuller transmission fully electronically controlled automatic transmission.

How to prevent getting these problems in the first place?

To prevent these problems, you need to change the Eaton Fuller transmission oil as per the manual or when it is too dirty. This is the easiest and most effective way to take care of your vehicle transmission and also drive your vehicle in a recommended way.

FAQs: Eaton Fuller automatic transmission problems

Does Eaton Fuller make an automatic transmission?

The Eaton Fuller AutoShift™ is a partially automated Eaton® Fuller® transmission that automatically selects and engages the transmission’s gears. The driver must use the clutch to start and stop the vehicle. A shift begins when the Auto- Shift™ computer detects that conditions are right for a shift.

What are the signs of low transmission fluid?

The common signs of Low Transmission Fluid are:

  • Unusual Noises: If your transmission is working properly, you shouldn’t hear any noise while you’re driving as it should transition smoothly. If not then this is sign of low transmission fluid
  • Burning Smell:  Any bad smell coming from your car should direct you to your nearest service center. As it might cause further damage to the car
  • Transmission Leaks: This is the most common and obvious sign of low transmission fluid which can cause a seizure.
  • Slipping Gears: You might notice this sign of slippage when you shift and this is due to low tranny fluid.
