Allison Transmission Wiring Harness Problems And Solutions

Today’s semi-trucks are all equipped with Allison Transmission Wiring Harness, and while they provide an invaluable service they can also experience issues. If a truck’s transmission wiring harness fails, it can mean costly downtime and a major headache for the driver.

Trucks powered by an Allison Transmission are highly reliable in principle, and issues with the wiring harness can often be traced back to something other than the transmission itself. Most of these issues are simple enough to identify and can often be remedied quickly.

The most common issue is corrosion, caused by moisture seeping into the insulation on the wiring harness. As any trucker knows, moisture and electricity don’t mix well, so corrosion will eventually cause problems. If the corrosion is not addressed in a timely manner it could create additional damage to the vehicle or even cause a system failure.

The first step in solving any wiring harness issues is to check for moisture damage. If there is evidence of corrosion, it’s important to remove the wiring harness from the transmission and inspect it for signs of damage. If any damaged wires or connectors are found it’s best to replace them with new ones.

In addition to corrosion, another common reason for Allison Transmission wiring harness issues is a poor connection. This can be caused by loose or corroded connections, as well as worn terminal leads. In order to fix this problem, it’s important to make sure all connectors are secure, and that the terminals and leads are in good shape.

Finally, it’s important to keep the wiring harness clean and free of contamination, as dirt and grime can cause corrosion and other problems. A quality cleaning agent should be used to remove any dirt or grime, and the wiring harness should be thoroughly dried before being reinstalled.

In conclusion, the Allison Transmission wiring harness can pose some issues for truckers, but by following the above tips most problems can be easily identified and corrected. If you experience any difficulties with your truck’s wiring harness, take the time to inspect it and make sure everything is in order. Doing so will help ensure your transportation runs smoothly and your profits remain high.
