Automatic Transmission | 2011-2016 GM 6.6 Duramax LML

The Allison transmissions used in the Duramax powered GM trucks have proven themselves over the past decade. 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 can throw at them.
And 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.
