The Disadvantages of Swapping Your Chrysler Transmission for an Allison Transmission

When upgrading your Dodge or Ram pickup, the allure of swapping your Chrysler transmission for an Allison is understandable. The Allison transmission is often praised for its durability, making it a tempting choice for those seeking enhanced performance. However, before diving into this swap, it’s important to weigh the disadvantages. From the challenges of retrofitting to the complexities of troubleshooting, an Allison transmission may not be the optimal solution.

The Hassle of Retrofitting: Is It Worth It?

One of the biggest drawbacks of swapping a Chrysler transmission for an Allison is the retrofitting process. Unlike the transmission originally designed for your Dodge or Ram, an Allison requires extensive modifications to fit properly. This includes custom mounts, wiring harnesses, and significant adjustments to your vehicle’s computer system. These changes are not only time-consuming but can also be costly, leading to unforeseen expenses. The more you alter the original design, the greater the potential for complications.

Troubleshooting Challenges

Even if the swap is completed successfully, troubleshooting issues with an Allison transmission can be a major headache. Finding a shop that is knowledgeable about both the Allison transmission and the specifics of your truck’s setup can be incredibly difficult. Many repair shops lack the expertise and tools required for diagnosing and fixing problems with a retrofitted Allison transmission, which can leave you facing high repair costs and extended downtime.

The Strength of a Properly Built Chrysler Transmission

It's no secret that Chrysler transmissions, such as the 48RE and 68RFE, aren’t renowned for their strength in stock form. This is often why many consider switching to an Allison. However, while these transmissions may struggle with stock power levels, they can be significantly improved. By investing in a properly built Chrysler transmission, you can achieve the strength needed to handle both the power of your truck and any additional power enhancements you’ve made. These upgrades can transform your stock transmission into a robust system capable of meeting the demands of serious hauling and towing.
