People who own recreational vehicles or motorhomes should already know how important it is to maintain them.

You have to ensure that your engine, batteries, and tires are in the best condition possible. Additionally, you have to look out for your vehicle even when It is not in use. The user has to remove their tires when keeping their motorhome stored for a long period.

This is because the pressure from their vehicle can damage the tires after which you will have to replace them. Aside from all this, the transmission of your vehicle is also another important thing to look out for. Allison is among the best companies when it comes to these systems.

However, there are also some issues that you can run into with these. Considering this, we will be using this article to provide you with some common problems that can be found on the Allison 1000 Transmission along with their fixes.

Allison 1000 Transmission Problems

  1. Limp Mode

The Allison 1000 Transmission system is one of the most powerful ones from the company. This is why it is mostly used in larger vehicles like motorhomes or RVs.

However, you should note that there is also a flaw with these systems. While this problem is quite rare and not a lot of people will run into it. You should still note that this can happen with your vehicle as well which is why you need to look out for it.

The issue is known as limp mode, where the transmission system on your vehicle gets locked into the third gear. If you ever find your motorhome in this condition, then there is no way to fix this.

You will have to either get your entire transmission replaced or get it rebuilt by the company. Considering this, you must know what causes this problem.

There are mainly two things that can make your system get into limp mode. This either happens when you are putting on too much pressure on the vehicle.

Alternatively, this can also happen when your transmission system is getting overheated. This is why you should look out for the weight you tow down to your motorhome.

This will help you to prevent issues as well as help the vehicle sustain its life. You should also keep in mind that the limp mode is a feature that prevents your vehicle from getting damaged. The transmission locks itself to protect your engine and chassis from running into further issues.

  1. Installation Problems

Sometimes the user might notice that their transmission system is not working properly. Alternatively, it might be completely dead for you.

While the first thing that comes to mind is that there is an issue with your system. You should note that in some cases, the problem can be with your installation instead.

Setting up the transmission system from Allison can be quite complicated if you are not aware of how it works. This is exactly why the company provides its users with a manual that they can follow.

Other than this, you can even take your vehicle to a workshop where they will install the transmission for you.

Though, if you want to fix the problem on your own then there are some things that you can look out for. Make sure that all the vacuum lines and parts are in the right position and connected. Installing back in any pipes that were disconnected or loose should most likely fix the issue you were getting on your transmission system.

  1. TCM Module Issue

The Allison Transmission 1000 is an amazing system that comes with tons of features. Though, you should keep in mind that this was released back in the 2000s.

Talking about this, the system had an issue with one of its parts. This is why the company asked all of its users to contact them and get the TCM module on their system replaced.

Considering this, if you have not gotten the module in your vehicle replaced by the brand. Then you should contact them as soon as possible and ask for the replacement of this part. It is best that you get this fixed as driving around your vehicle with a faulty TCM module can be quite dangerous.
