2001-2019 GM 6.6L Duramax SDP Built Allison Transmission w/ Billet Torque Converter SDP-1037

The 2001-2019 GM 6.6L Duramax SDP Built Allison Transmission w/ Billet Torque Converter is Fit for Any Application

This Allison 1000 is built in house to the highest of standards and includes a Goerend triple disc billet torque converter. All of our Allisons are built the same (clutch pack stackup) whether you're looking for a 1000+RWHP truck or you're looking for a reliable transmission for your 500HP daily driver. Our transmissions have been in several dozens of 1000+RWHP trucks with lots of abuse drag racing, dyno runs and sled pulling all on the same build for a full season. No matter your power level or what you do with the truck, we use the most robust clutch pack combinations possible, which is why we feel more than comfortable with being able to offer the lifetime warranty for an additional cost in sub 650rwhp applications. We set them up according to your predicted power level and we can add billet shafts/hub, C3 PTO oiling holes or a pan for the cost of parts. It is preferred to use your current transmission that is in your truck but we do have over 100 cores on the shelf which we can use to build one to order with specs for your truck and how you drive.
