The Basics of Heavy-Duty Transmission Overhauls

Heavy-duty transmissions are the foundation of many commercial and industrial vehicles. 

They are responsible for transmitting power from an engine to the wheels, allowing the vehicle to move forward, backward and stop. 

Over time, these transmissions can suffer from damage or wear, which can reduce their efficiency and lead to costly repairs. 

The best way to avoid these costly repairs is to perform regular overhauls of the transmission

In this article, we will discuss the basics of heavy-duty transmission overhauls and the steps that need to be taken to ensure the job is done properly. 

Inspecting for Wear & Damage

The first step in performing a heavy-duty transmission overhaul is to inspect the transmission for any signs of wear or damage. 

This inspection should include a visual inspection of the transmission housing, seals, and other components. 

If any signs of wear or damage are identified, these should be addressed before proceeding. 

Once the inspection is complete, the transmission should be removed from the vehicle and taken to a specialised repair shop. 

Here, the transmission should be disassembled, and all of the components should be thoroughly cleaned and inspected. 

Any worn or damaged components should be replaced, and all of the internal parts should be lubricated and reassembled. 

Check & Replace Transmission Fluid

Before reinstalling the transmission, the transmission fluid should be checked and replaced if necessary. 

The transmission fluid should be changed according to the manufacturer’s recommended intervals, as this will help ensure the transmission is operating properly. 

Once the transmission is reassembled and reinstalled in the vehicle, it’s important to perform a test drive to ensure the transmission is working correctly. 

Test Driving the Vehicle

During the test drive, the transmission should be shifted through all of its gears to ensure that it is shifting properly and that there are no signs of wear or damage. 

Also, the vehicle should be taken on a long drive to ensure that the transmission is functioning properly at higher speeds.
