If you drive a vehicle with an automatic transmission, chances are you have at least heard of the transfer box. It's an essential component in the transmission system and can cause a variety of problems if it fails. So, what are some of the common issues?
What Is a Transfer Box?
This is a part of your transmission system that is typically located close to the gearbox. It's responsible for regulating how the power is transmitted to each axle or, in other words, transferring torque to the front or rear wheels or all four wheels at once. So, for example, if you only have a part-time four-wheel-drive system and engage the 4WD lever in the cabin, this will activate the transfer box. You will then have traction at both the front and rear, which can be particularly handy if you have to negotiate a slippery road or are driving on a dirt track.
Harsh Shifts
One of the first signs of trouble with your transfer box is harsh or jerky shifts between gears while driving. In most cases, this is due to worn-out components inside the transfer box itself. These parts often deteriorate due to normal use and must be replaced in order to prevent further damage. It's important to note that these parts should only be replaced by trained professionals, as incorrect installation can lead to further issues down the line.
Low Fluid Levels
Low fluid levels can cause major issues such as premature wear on internal components, slipping gears, and difficulty shifting between gears. It's important to check your owner's manual for information about how often you should change your car's transmission fluid and how much of it your vehicle may require. By replacing old fluid on a regular basis, you can help ensure that your car will stay running smoothly for years to come.
Loss of Power and Performance Issues
In some cases, failure may result in a complete loss of power or performance problems when driving your vehicle. If your engine appears to be stalling or backfiring, this could also indicate potential issues with the transfer box and should be addressed immediately by qualified technicians.
What to Do Next
If you've noticed issues that could be traced to a transfer box problem, take the vehicle to a mechanic as soon as possible. They'll be able to carry out certain tests and, if they find anything wrong, rectify it as soon as possible.
