19431596 Genuine Allison T14 A50 Transmission Control Module NEW

If you own a 09-15 GM HD truck, it's important to be aware of the symptoms of a failing Allison A50 T14 TCM. When the TCM is failing, the most notable symptom is hard shifting. This can be harmful to your transmissions internal components and even your driveshaft U-joints. In worst-case scenarios, the transmission may enter "limp home mode," where it gets stuck in third gear due to a loss of communication with the TCM. Ignoring the issue can lead to further damage and increased repair costs. If you notice any of these symptoms, it's essential to get your vehicle checked immediately to avoid any potential towing bills, lost productivity, and expensive repairs. Even if your TCM is not yet showing any signs of failure, it's a good idea to schedule an Allison TCM repair during your next maintenance service.

Here are common DTC diagnostic trouble codes associated with Allison A50 T14 TCM failure:

• U0101, U0100 - Lost communication with TCM
  P0700 - Faulty Transmission Computer Module
