The Allison 1000 has no doubt proven itself since its mating in 2001 behind the first Duramax equipped GM trucks. Its longevity, even when pushed with moderately heavy loads and higher horsepower have put it at the forefront of transmissions until recently. However, as miles and horsepower accumulate, these transmissions will find their failure points, and ATS has the cure to ensure your horsepower is getting to the ground efficiently.
By increasing the capability of the torque converter, clutch surface area, and line pressure, the transmission can hold 200% more torque than stock. The result is a setup strong enough to handle aftermarket fueling, turbo(s), and tuning, yet is still smooth enough to tow and daily drive with.
As with all ATS Transmission Packages, this transmission is covered by a 5 year / 500,000 mile warranty.
SHIPPING POLICY - PLEASE READ - Due to the size and weight of transmissions, they cannot be shipped through traditional couriers, such as UPS, FedEx, USPS, etc. and MUST be shipped via truck freight. For this reason, we cannot offer free shipping on transmissions. However, we do offer the option to pay for return shipping up front. If you select this option once your core transmission is ready to be picked up, you just need to give us a call with your original order number and the core tag on the transmission, and we'll take care of the rest. As always, if you have any questions, give us a call or send us an e-mail.

What hp is this trans rated for?
this is rated for 400 HP
In the question above, verified answer is the trans is rated for 400hp. Why is it listed in the ""700 hp"" recipe for the LML duramax??
Currently the stage 1 is the only performance trans option we offer, this coupled with the correct transmission tuning and supporting mods, can get you into 700hp.
How much hp can this stg1 allison handle the purple one?
With the upgraded converter and clutches depending on how your truck is setup it could support up to about 550hp. There are many thing that could effect that rating like improper gear ratio to tire size. If you are running mismatched of that you are putting an enormous amount of stress on the transmission and might only be able to go say 450hp. -Sands
