The Chevrolet Avalanche has been in production since 2001. Known as a convertible [meaning it can be converted from a] truck to a 4 door passenger vehicle in a matter of minutes. Only 2 transmissions have been offered, both are automatic transmissions, one is a 4 speed automatic overdrive transmission and the other is a 6 speed automatic transmission. Both transmissions use a lock up torque converter. GotTransmissions.com has both Chevrolet Avalanche Transmissions for sale at very affordable prices.
The 4 speed automatic is called a 4L80E upgraded, which is part T400 [GM’s original heavy duty 3 speed automatic transmission] and has an overdrive section on the front. It uses an aluminum case which is completely different than it’s predecessor. The E stands for electronic.
This is a rear wheel drive transmission, or longitudinal mounted engine transmission setup. Meaning the engine and transmission are in the front, and the differential is in the rear, using a drive-shaft to connect them.
It uses a sophisticated electronic system combining the input signals from sensors that track engine rpms [revolutions per minute] and road speed to decide when to shift. Using a lock up torque converter, it is in essence like having another forward gear, making 5 forward speeds. It is one heck of a heavy duty transmission, well suited to any type of duties.
The 6 speed automatic transmission is made by Allison Transmissions, which is division of General Motors that manufactures truck transmissions. Called the Allison 1000, it has a total of 6 forward speeds and a lock up torque converter, thus having 7 forward gears. Staggering to say the least.
Capable of handling the most difficult and torturous conditions, it is an overkill of sorts. Which in my opinion is great. Capable of handling around 625 pounds of torque, unless something unexpected occurred like a a bad fluid leak causing a failure, this may be the strongest transmission offered in a light duty vehicle in the world.
The original Allison 1000 had 5 forward speeds, with a 6th speed added in 2006. It allows for more control in situations where a big heavy load is being carried and more control is needed and safer. Very much like the way heavy duty truck transmissions operate.
