How much HP can an Allison Transmission hold?
As you’ve probably deduced up to this point, the stock Allison will handle roughly 350 to 400-rwhp in five-speed form and 425 to 450-rwhp in six-speed trim. However, if you push things past that point the clutches will eventually slip and bring on the Allison’s notorious “limp mode” condition (i.e. limp home mode).
How many miles can you get out of an Allison Transmission?
Like toypuller said, on a 100% stock motor, and when properly maintained they seem to pretty much last indefinitely. If you severely overpower it, you can kill it within 100 miles if you want.
Are there any changes to the Allison 1000 transmission?

How does the Allison Transmission work for Duramax?
The Allison’s external filter eliminates the need to frequently service the internal filter and greatly reduces maintenance time/cost. It also relies on adaptive technology which integrates the transmission with the engine control module to continuously monitor driver input and calculate ideal shift strategies for the particular driving conditions.
How much fluid does a Duramax Allison 1000 have?
* 6th gear available in 2006+ model years. Dexron-III (5 spd models) or Dexron-VI ATF (6 spd models), roughly 13 quart total fluid capacity and 7.4 quart refill capacity w/ filter change. The Allison’s obvious strength is its robust size, as the 1000 series transmission is designated for medium duty applications.
Can you tell the difference between A 2500HD and an ally 4×4?
I had a 2500HD 4×4 w/ 8100 & Ally for a few years and have owned a 2500 4×4 Sub w/ 8100 & 4L85e for over a decade. I eventually had the ecm in the truck tuned and had torque management removed, and it was definitely noticeble on the bottom end (couldn’t tell a difference in mpg).
