Please check notes in each part listing to ensure the Auto Trans Differential Carrier is correct for your 2009 HUMMER H3T with a 3.7L DOHC engine. Special restrictions like "California only" or "with sport package" may indicate a Auto Trans Differential Carrier fits only certain 2009 HUMMER H3T models.
Clicking a "More Info" link will display a picture and/or other details about that Auto Trans Differential Carrier in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Auto Trans Differential Carrier, click the "Add Part" button. Shipping costs will be shown on the Shopping Cart page. You may use your browser's Back button or click "Find More Parts" to find more Transmission-Automatic parts, other HUMMER H3T parts or parts for a different vehicle. Please try our Interactive Catalog (click link above) for faster searching. Both catalogs use the same shopping cart so any auto parts you've already chosen for your 2009 HUMMER will not be lost if you switch.
