Is the Duramax Allison 1000 a manual transmission?
Rather than becoming outdated, the Allison has evolved to match the performance characteristics and demands of the Duramax turbodiesel, which has undergone significant changes itself through the years. Manual transmissions are relatively rare for Duramax powered GMC/Chevrolet pickups, the primary reason being the attractiveness of the Allison 1000.
What kind of pulling power does an Allison 8.1L have?
TM has little to do with pulling power, mostly for the transmission shifting and smoothness. In defense of the 8.1L, it is a decent long life engine that gave reasonable pulling power for Suburbans and pickups in the gasser class. Mine had the famous CSK and oil consumption even though it was pampered from the beginning.

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.
Is the Allison 1000 a manual or automatic transmission?
General Motors was the first of the “Big 3” to phase out a manual transmission option for their diesel – the ZF 6 speed was last offered for the 2006 model year. Modern automatic transmissions, such as the Allison 1000, are far superior to manual transmissions in almost every category.
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.
What are the different types of GM transmissions?
Other automatics 1 Aisin AF33 — 5-speed transverse automatic made by Aisin AW Co., Ltd. 2 Allison 1000 Series — 6-speed longitudinal automatic made by Allison Transmission 3 Saturn MP6/MP7 — 4-speed automatic developed by Saturn for use in the S-series from 1991 to 2002 4 VTi transmission — continuously variable transmission
