Is the Allison 1000 transmission good?
While there’s nothing overly exceptional about an Allison 1000 transmission, the gearbox has a longstanding reputation for reliability and continuous improvement. One of the first uses of the five-speed 1000 transmission was its pairing with GM’s Duramax 6.6-liter V-8 Diesel engine.
How much HP can a Allison 1000 handle?
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.

How many miles does an Allison Transmission last?
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.
