Explore our stock replacement transmission, perfectly suited for 2001-2010 GM trucks or SUVs equipped with an Allison transmission, specifically the 8.1 or Duramax models. Our team includes a Master Certified GM Technician, and with over 18 years in business, we've crafted transmissions capable of handling 500-1200 horsepower. This particular advertisement features a pre-built transmission complete with a billet torque converter, ready for installation.

Please note, the price does not include installation, shop supplies, hazmat fees, taxes, or costs associated with hard part failures. The transmission comes with a 12-month, 12,000-mile parts and labor warranty if installed at our facility or by a reputable shop, and a 6-month, 6,000-mile warranty if installed elsewhere. Our warranties are valid only at our facility and apply to stock horsepower; aftermarket accessories will void the stock transmission warranty. The listed price requires the exchange of a good core, with a $1,000 core charge applied for visible external damage and an additional $250 core charge for internal hard part damage.

For those seeking enhanced performance, we offer upgraded transmissions that come with up to a 3-year, 36,000-mile parts and labor warranty, tailored to specific horsepower ratings.
