How to Fix Range Shift Inhibited Freightliner Trucks


freightliners

Range shift inhibited freightliner is a common problem on the road. It can cause your truck to run out of fuel, and sometimes you’ll have to drive it to a fuel station. But when a range shift inhibits your freightliner, there’s no way for you to know where the fuel is located. This can lead to a lot of troubles, including lost time and money. 

Range shift inhibited freightliners are often caused by bogged transmissions, lack of down time and incorrect oil changes. The HEMI 6L00D engine on these trucks runs on unleaded gasoline, which can cause problems with the fuel economy and emissions.

You will need to fix range shift inhibited freightliners by removing the offending gear, value the engine, and getting an accurate dyno report on it to ensure that it is still in good condition.

The Causes of Range Shift Inhibited Freightliners

Range shift inhibited freightliners can be caused by a number of things. The most common reason is that the transmission is in need of repair or replacement. 

There are a few other reasons that range shift inhibited freightliners are caused such as:

  • The engine needs to be serviced, this is often the cause of an incorrect fuel economy, engine knock, and high fuel consumption
  • The truck has been driven too long between oil changes, this causes excessive wear on the engine causing it to lose power and become sluggish.
  • The truck has been overworked causing the transmission to overheat and become damaged. This damages the fluid in the transmission causing it to lose power and slip out of gear.

Now, let’s take a look at how to fix these issues.

How to Remove the Gear from the Transmission

One fix for your freightliner being inhibited by the range shift is to remove the gear from the transmission.

Follow these steps:

  1. The first step to removing the gear from the transmission is to get out the truck and inspect it. You will need to check for any leaks, damage, or other issues that could cause harm to you. 
  2. If there are any issues, you should report them to your supervisor immediately so that they can be fixed before continuing on with removing the gear from the transmission. 
  3. If everything is good, you will need to remove the engine from the truck. This is a simple process of hooking up a winch and pulling it out of place. 
  4. Once you have removed the engine you will need to drain all of the fluid in the transmission by removing all of its lines and letting it drain into a bucket or other container.
  5. Remove the planetary gear set. This is a simple process of removing the bolts that hold it in place. Once you have removed those bolts, you can remove the planetary gear set and replace it with a new one. 
  6. You will need to install new seals and gaskets to ensure that no oil leaks out of your transmission while it is running again. 
  7. Once everything has been replaced and secured, simply refill your transmission with new fluid and get everything back together.

Your truck should be ready for work again in no time!

Value the Engine and Remove any Harmful Pollutants From It

The first step is to remove the offending gear from the transmission. This will help to prevent the truck from losing power and being stuck in neutral. 

The next step is to value the engine and remove any harmful pollutants from it. This will ensure that the engine is still in good condition and can run on Unleaded gasoline.

Get a Dyno Report on the Engine to Ensure It’s In Good Condition

If you are not sure if the engine is still in good condition, it is best to get an accurate dyno report. A dyno report will allow you to see how the engine is performing and whether it is still running at its original specs. 

This will help you determine if range shift inhibited freightliners are causing the truck to lose power or be stuck in neutral. If your Dyno Report is clear of issues, you are good to go!

Conclusion

In order to fix range shift inhibited freightliners, it is necessary to take a detailed look at the engine and gear. If the engine is in good condition, remove any harmful pollutants, and get an accurate dyno report to ensure that the engine is still in good condition. 

If range shift is preventing the truck from moving, it is necessary to fix the transmission and value the engine.
