Transmission Control Modules & Units

Transmission control modules are a great option to add transmission-shifting performance for your vehicle. JEGS offers a wide selection of transmission control modules, transmission gaskets, and other transmission products from top manufacturers such as MSD Igntion, TCI, FiTech, B&M, and others. Each transmission control module is made from high quality components and assembly so you can get the transmission performance you want at a price you can afford with the assurance you need.

What Are Transmission Control Modules & Units Common Pros and Cons?

Transmission control modules (for example, a 4L60E transmission control module) manage shift firmness and shift points on electronically controlled transmissions. Aftermarket options allow you to make changes to transmission shifting behavior for improved performance. Because control modules are complex, they can be expensive to purchase.

Which Transmission Control Modules & Units Are Best?

When choosing an aftermarket transmission control module, the first step is to research and confirm which model of transmission you have. Once this has been established, the next step is finding all transmission control module options that match. From here, choose the one that meets your budget and application needs.

How Much Do Transmission Control Modules & Units Cost?

Most transmission control modules range in price between $300 and $2,000, depending on the transmission model, options, and brand.
