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 2-4 business days, please call or email 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 $675 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 $100 extra for the crate that it will be returned to you with, the transmission must be crated to have insurance on the shipment.

 

*We recommend that you add an aftermarket transmission cooler 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.

*The core must come back 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 4-5 business days for inspection before the core refund begins processing.
