Eaton Ultrashift Problems Solved

Eaton is a company renowned for manufacturing truck and automotive products. One of their highly regarded products is the ultrashift, which is basically a manual or automatic transmission for trucks.

Because of the wide popularity of this feature, a number of consumers have been keen on purchasing these vehicles equipped with ultrashift features. Unfortunately, there are some issues linked with it, which often arise almost immediately upon purchasing their truck. 

Here are among the common Eaton ultrashift problems and how to diagnose and solve them.

1. Starting issues

The most common problem with the Eaton ultrashift is a starting issue. Because of defects to the ultrashift, there have been instances when some error codes appear on the dashboard of your truck. This is quite a concerning problem among daily users because of the hassle it brings.

One way to address this issue is to check and troubleshoot a few things such as:

  • XY shifters
  • Fuses
  • Computer
  • Error codes
  • Software
  • Sensors
  • Shifter’s wiring

Hence, if you notice that your truck is displaying some error codes on your dashboard, you can use your OBD2 scanner. Then, match these codes with your manual to determine the cause of these errors. 

When you have fixed an error code, yet there is still an error displayed, you need to check your XY shifter. You may need to get your XY shifter replacement to get rid of the error code completely. 

If your shifters are still under warranty, then there should be no problem with getting them replaced. But there is no guarantee that the problem will no longer persist even after replacing the shifter. 

In this case, you need to inspect the wiring and check if there are defects or damages to them. Sometimes, some loose points can also cause error codes to appear. With this in mind, you will need to get your wiring replaced completely. 

But do take note that your fuse can also be triggering these codes. This is why the next thing to do is to inspect the fuse in your fuse box. If there is a faulty or blown fuse, you will need to get it replaced by a specialist. 

And lastly, the software may also be causing these Eaton ultrashift problems. If so, you need to have your computer software updated. You can easily get it done from your authorized dealership.

There are also instances when defects in the computer can contribute to these ultrashift problems. Be sure that your computer is free from any issues and get it replaced if need be. Do take note that this process can be rather expensive. So, if your vehicle is still under warranty, you will be able to get the computer changed free of charge.

It is also worth noting that you may want to inspect your ultrashift sensors. If there are defects to these, then problems can arise. So, it helps to simply purchase brand new sensors and replace defective ones.

2. Gear shifting issues

A number of ultrashift problems with the Eaton is linked with gear shifting concerns. What this means is that your gear fails to shift and can even get stuck. If so, you need to inspect what exactly is contributing to this issue and get it addressed sooner than later.

You may need to replace your XY shifters, as well as the sensors with better ones to resolve the problem once and for all.

But if the XY shifters and sensors are not causing these problems, and yet you still experience issues, then you may want to inspect your transmission controller. Contact a specialized mechanic to get this component checked and have it replaced when necessary.

3. Gear slipping

There are also cases when gear slipping may arise, which can be quite a hassle to many people. What this means is that your vehicle may not accelerate while at the same time the gears tend to slip as you go uphill.

One thing you need to know about this problem is that the clutch system is most often associated with it. Hence, you will have to get your clutch replaced to address this issue.
