allison 1000 2000 series tcm pinout

The Allison 1000 and 2000 Series transmissions are some of the most popular automatic transmissions used in heavy duty trucks. With their powerful and reliable design, they are favored by truck owners who need to move heavy items over long distances. But with all that power comes a complexity in the wiring of the transmission control module (TCM), which is the part that controls the transmission’s operation. To ensure proper performance of the transmission, it is important to understand how to access and read the transmission control module pinout.

The Allison 1000 and 2000 Series TCM pinouts are the same across all models. The pins are numbered 1-7, with each number corresponding to a specific electronic signal. For example, pin 1 is the ground signal, pin 2 is the power input, pin 3 is the shift solenoid A input, and pin 4 is the shift solenoid B input. Each pin has to be correctly wired in order for the transmission to operate correctly.

When dealing with your Allison transmission, it is important to have a good understanding of the TCM pinouts. Knowing how to access and read the pinouts can help you troubleshoot any problems you may encounter with the transmission. Additionally, knowing the pinouts can give you insight into how the transmission works, so if you have to replace a part, you will know exactly how to wire it in. Whether you’re a professional or a DIYer, having a good understanding of the Allison 1000 and 2000 Series TCM pinouts is essential.
