RevMax Allison 1000 Signature Series Transmission | 2017-2019 GM Duramax 6.6L L5P

ALLISON 1000 L5P 6 speed Signature Series performance automatic transmission. These units are built to the most stringent tolerances by one expert technician from beginning to end, and each unit is signed by the technician when finished. This unit is rated at up to 1500HP (shafts will need to be upgraded) and has undergone over a year of rigorous R&D and performance testing. We don’t just say we have pride in our transmission, we literally put our name on it. This transmission features the following:

This transmission contains internal parts with the ability to hold up to 1500HP. However, this will require upgrading the shafts in the transmission. Unlike our competition, we do not leave optional upgraded parts out when we build our units. We do not have stages or levels as our transmissions ALL come fully built with no available upgrades other than billet shafts. We recommend upgrading the input shaft for any customer towing making over 850HP. As for the output, we recommend this for customers who will be doing boosted launches and making over 1000HP. We only recommend upgrading the intermediate shaft for those customers who will be producing over 1500HP and will be racing the majority of the time.

Not only do we have the best internal parts in our units, we have spent over $150k in valve body testing equipment to provide our customers with the best tested and performing valve body that money can buy. Each valve body is custom configured to our customer’s truck and individual tested prior to being installed in the transmission.
