We program the Transmission Control Module to the specific VIN you provide before we ship it. It will arrive ready for installation, with no additional programming required. **How do I provide my Vehicle Identification Number (VIN)?** After you complete your purchase, you will receive instructions on how to send us your VIN. You can also add your 17-digit VIN to the ‘notes’ section during checkout for the fastest service. **Is this the correct part for my vehicle?** This module fits the 2005 Trailblazer EXT and many other 2004-2005 GM models listed. Please check the provided compatibility list and verify that your original part number matches one of the numbers listed in the description to ensure a perfect fit. **Could something else be wrong with my transmission?** Yes. This module will fix faults within the transmission’s electronic control system. It will not fix internal mechanical problems like worn clutches or a bad valve body. It is always recommended to have a qualified mechanic perform a full diagnosis to rule out mechanical issues before replacing electronic components. **What is the Core Relearn or ‘CASE’ Relearn procedure?** In some cases, after installation, your mechanic may need to perform a Crankshaft Variation Relearn (often called a CASE relearn) with a high-end scan tool. This simple procedure synchronizes the new module with the engine’s crankshaft position sensor and is a standard final step for many electronic component replacements. Please enter it in the payment notes and save to ensure we receive it. Orders without a VIN within our 2-business-day handling period may be canceled, as programming cannot proceed without it. ### Shipping - **Processing Time:** Reliably shipped within 2-3 business days. ### Warranty Enjoy peace of mind with a **one-year replacement warranty** on this part, effective from the date you receive it.
