Common questions

How much power can an Allison Transmission handle?

How much power can an Allison Transmission handle?

It’s the electronic side of the transmission sensing excessive slipping and placing the unit in fail-safe mode, where only one forward gear is available. 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 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.

Which is the automatic transmission on a Duramax Diesel?

The Allison 1000 has been the standard automatic transmission for the Duramax diesel since its inception in 2001.

When did GM stop using the Allison Transmission?

GM sold Allison Transmission in 2007, although Duramax powered pickups continue to use their transmissions. Moderate changes have occurred to the transmission throughout the years however the platform itself has, for all intents and purposes, remained the same since 2001.

When does the Allison transmission warm up in the summer?

These transmissions will warm up when towing or driving in the summer months. 200-225 is very common when the ambient air temp is 80-100 degrees and your transmission is under an increased load. Temperatures from 230-240 have been reached with no damage to the transmission.
