Review on 🔧 GM Genuine Parts 15281541: Black Automatic Transmission Fluid Fill Tube - Reliable and Authentic by Jerry Leon

Excellent quality, perfect fit. No change required. Be sure to order a new rubber seal or bushing for installation and schedule transmission service during installation. My factory seal was very brittle and a few pieces fell into the swamp area. Due to the construction, this cannot be prevented. For the Hummer H3 you will need a transmission filter, gasket kit and 5 liters of Dextron VI. Cross-tighten the flat head screws to 9 ft/lbs or 180 in-lbs.
