Description
Allison has been supporting the Duramax equipped GM's since their infancy stage with the release of the first 2001 model. Over the years, the Allison has naturally progressed with the added power and features that the Duramax has produced. Beginning with the 2020 model year, the L5P engine was again, upgraded, so it was evident that the transmission would need some finesse to support this newfound power. Presto, the the 10 speed Alison 10L1000 was introduced now power-holding and fuel mileage were combined into one unit. The 10 speed Allison is a work of art. This engineering marvel is
something from the future. Extremely compact and lightweight for its
torque capacity yet packing 10 speeds!
However, as with ALL transmissions, they have their breaking point. We have found that prevention can be one of the key successors for a long lasting transmission, which is why we highly recommend adding a quality deep sump transmission pan and Schaeffer's brand transmission fluid to your Allison, no matter how you use it. And for those that are seeking higher horsepower or have accumulated some miles and are in need of heavier duty internals, we carry upgrades ranging from ATS, BD, and AFE torque converters to full blown billet transmissions that can handle ANYTHING you want to throw at them.
As always, if you need assistance in determining the correct parts for you, give us a call or send an e-mail to cs@dieselpowerproducts.com and we would be happy to help.
