Product Description

SDP 750HP Built Allison 1000 Transmission with Billet Torque Converter

*Freight includes shipping BOTH ways and it must be a commercial address with a forklift or extra shipping charges may be applied.

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. Current lead time is 15-20 business days, please email orders@sdptwins.com to verify.

We can have your transmission shipped to us to build, or build one of our cores to your specs and ship it to you. Contact us regarding shipping costs and times. Our fixed rate of $1075 is for round trip freight (to you and your core back to us is included) if going to a commercial address with a forklift. If you send your transmission to us on an open pallet, we charge $165 extra for the crate that it will be returned to you with, the transmission must be crated to have insurance on the shipment. The transmissions ship without the converter in them, they are drop shipped separately as to not put stress on the pump.

*We recommend that you add an aftermarket transmission cooler (do not use Mishimoto brand as major leaks from the soft hose/worm gear clamps are prone to leaking with trans failure) if you plan to tow heavy in higher temperature climates (factory or AN lines only, we do not approve of crimping soft hose to the factory hard line as it will blow off over time with the added pressure and cause failure).

*The transmission cooler and heat exchanger MUST be cleaned using a HotFlush machine, and the TCM must have the TAPS reset (in some cases, a new TCM may be required).

*The core must come back within 30 days in rebuild-able condition in order to qualify for the full core refund. This includes but not limited to; planetaries, pump housings, shafts, gears, housings etc. Please allow 10-15 business days for inspection before the core refund begins processing. $300 applies to the torque converter, $400 for the shipping crate, and $1,300 for the transmission itself.

*The Powdercoating option will add at least 2 weeks to the current build time. If you select a Goerend Pan and powder coating, the pan will be coated to match, the Mag-Hytec pan will be left in their standard black powder coated color unless otherwise discussed.
