When did GM stop using the Allison 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.

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.

Rather than becoming outdated, the Allison has evolved to match the performance characteristics and demands of the Duramax turbodiesel, which has undergone significant changes itself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 truck is a Silverado Sierra?
My truck is a 2004, with an 8.1, a 5 speed Allison, and 4.10 gearing. However, mine has 6” of lift, and 35” tires. My trailer is a hybrid, with a toy deck on the front. 29’ long, 3860 dry, 4381 loaded (but without my gear, and toys), and 7100 gross. The performance, and gas mileage you describe (loaded, and unloaded) is typical of mine as well.
What are the weaknesses of the Allison Transmission?
This allows for low engine speeds at cruising rpm and ultimately opportunities for significantly reduced fuel consumption in relative terms. The Allison is not without a few weaknesses, which include insufficient lubrication to the C3 clutch and the off-center engagement of the C1 and C2 clutches.

What should the temp of an Allison Transmission be?
How hot should your Allison transmission run? If you own a 2001-2004.5 LB7 Duramax your normal operating temperatures will run around 160-180 degrees. 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.
