Quality and Experience are the two most important attributes to look for when shopping for a built trans. Here at Dan's Diesel Performance we have over 13 years experience in building Allisons and only use the best parts available on the market. A built transmission is a big investment so we want to offer the customer the best built transmission in the market. All DDP Built Allisons start out as good cores and are fully disassembled. All components and housings are washed in our Cuda 2840 aqueous parts washer to rid of any dirt and contamination inside and out. Then all components are carefully inspected for flaws and wear. Then they are assembled using the highest quality performance aftermarket and oem parts. We offer many different converter options and billet internals to meet your horsepower goals. The Goerend DK converter is the most popular unit we sell and stock.
