This transmission isnt just a basic rebuild, its a carefully engineered solution designed to bring enhanced durability and performance to one of GMs most popular platforms.

If your Allison 1000 is starting to show its age or you're looking for a solid upgrade to handle more towing, tougher terrain, or just everyday use with confidence, the BD RoadMaster transmission package is exactly what you need. Built specifically for the 2004.5–2005 Duramax LLY.

This transmission isn’t just a basic rebuild, it’s a carefully engineered solution designed to bring enhanced durability and performance to one of GM’s most popular platforms. The magic starts with a modified valve body that improves overall clutch performance and lifespan. Inside the transmission, BD keeps the stock clutch counts, but doubles the torque-holding capacity in the failure-prone C2 and C4 clutch packs, giving you far better holding power and way less slip, especially when towing or under heavy load. To help keep transmission temperatures under control, the RoadMaster package includes BD’s signature deep cast aluminum pan, which adds an additional 3.5 quarts of fluid capacity and helps dissipate heat much more effectively than stock. Every RoadMaster transmission also comes with BD’s billet ProForce torque converter. This converter is designed to deliver strong, consistent clutch engagement, even when the heat is on. Whether you're tackling steep grades with a trailer or cruising empty, the ProForce torque converter ensures your truck responds smoothly and confidently.

Before it ships, each unit is dyno tested for quality and performance. When it comes to peace of mind and real durability, the BD RoadMaster doesn’t mess around, it’s built to last and ready to work.

SHIPPING POLICY - Due to the size and weight of transmissions, they cannot be shipped through traditional couriers, such as UPS, FedEx, USPS, etc. and MUST be shipped via truck freight. We do not offer free shipping on transmissions, however, we do offer a very competitive rate charged at checkout. Once your core transmission is ready for pick up, you just need to give us a call or send us an e-mail with your original order number and the core tag on the transmission, and we can supply you with a quote on the return shipping as that is not covered in the original shipping cost. Otherwise, we give you the option to coordinate the return shipping on your own and independently pay your courier of choice. As always, if you have any questions, give us a call or send us an e-mail.

Strong and very convenient
Size: 50 Count
These paper bowls are sturdy and hold up well even with hot or liquid foods. They don’t get soggy easily and are microwave safe, which makes them very convenient. The size is also great for soups, cereal, or leftovers. Good quality for disposable bowls and very practical for everyday use.

Sturdy, great value, very utilitarian
Size: 50 Count
Exactly what I wanted. Exact quality thickness and sturdiness. Only small downside is they're coated in a wax like substance and stick together so you have to pry them apart and if you microwave something, it tends to meld together and also stick into the bowl. But I still love them especially the price.

Awesome Body Lotion For Dry Skin and Some Reduction Of Age Related Wrinkles
Scent: Sweet Vanilla & Soft Wood, Size: 18.5 Fl Oz (Pack of 1)
I have only been using this product for a short period of time, but I very much like the fragrance. The sweet vanilla and soft wood scent is a great combo and not overpowering. I like the texture of the lotion, which is a silky smooth clear gel and easy to apply. My age wrinkles are diminished and very much less pronounced. It makes my skin feel more supple, as I have dry skin and the lotion is perfect for that condition. It will definitely be my go to skin lotion going forward as I am very pleased with the cost and the improved skin condition is a very short period of time.
