    4L60 6AN KIT & Reservoir tank

    First off, the customer service is top-notch, and that is hard to find nowadays. I am still in the process of building my truck, so I have not used these two items yet, but the quality of the parts is excellent. I’m looking forward to ordering more parts in the future. Thanks again, Spencer, for the help!
