Our Allison-1000 transmission Upgrades
Late-OEM front pump covers eliminate cracking around torque converter pads.
Upgraded lube regulator valve and torque converter relief spring eliminate delayed engagements and reduce operating temperatures.
F-Trim valve sleeve greatly reduces possibility of overheated torque converter.
E-Shift valve spring enhances shift quality and increases durability.
Additional friction plate added to C3 clutch increases load capacity.
Completely remanufactured late design pump with new line bore bushings eliminates leaks and provides superior flow and durability.
Fully remanufactured torque converter is tested for leaks, lockup, concentricity, and balance. Upgrades exceed OE requirements and eliminate the possibility of front seal leaks, premature bushing wear, and vibration.
Bushings and machined surfaces polished to a mirror-like OE finish of 15 RA or less.
Tru-Flat qualification process applied to transmission case, valve body, pump, and channel plate prevent cross leaks and pressure losses
All-new custom-spec bushings to improve internal fluid flow control and pressures.
Every transmission is cold-and hot-tested using a proprietary dynamometer testing program that includes fully synthetic automatic transmission fluid and a filtration system.

Allison-1000 History & Information
The Allison 1000 transmission has a reputation for being a durable, reliable, and powerful transmission. The transmission was first produced in 1999 by Allison Transmissions. The transmission was used for a couple of years, General Motors (GM) paired the Allison 1000 transmission with its 6.6 L Duramax in 2001. One of the most reliable automatic transmissions, the Allison 1000 transmission, was placed in a wide variety of vehicles during the next few years because of its reliability and advanced technology along with its heavy duty capabilities. It provides smooth shifting, good gas mileage, and durable longevity in harsh conditions. In 2006, the Allison 1000 automatic transmission received a significant upgrade, converting it from a 5-speed automatic transmission to a 6-speed automatic transmission. As a result, the new Allison 1000 transmission became a double overdrive.
With the introduction of the double overdrive option (called the Generation 4 Allison 1000), the Allison 1000 transmission also offered manual gear selection. As a result, the driver gained additional control over the transmission itself. With the addition of operation over engine braking, and situations where less frequent shifting might be desired, the Allison 1000 transmission was introduced in a variety of vehicles. This includes all heavy-duty GMC Sierra 2500 and Sierra 3500 trucks, Chevrolet Silverado 2500 and Silverado 3500 trucks, and even appeared in the Hummer H1.
Eventually, the Allison 1000 transmission was phased out in later model years. The Allison line of transmissions underwent significant changes beginning in the late 2000s. The Allison 2000 transmission was introduced as a successor to the Allison 1000 transmission. Later successors were also introduced including the Allison 3070 transmission, the Allison 4070 transmission, and the Allison 3700SP transmission.
Even though the Allison line of transmissions did undergo significant upgrades with the Allison 2000, 3070, 4070, and 3700SP, the Allison 1000 transmission is still in use to this day because of its durability, flexibility, and reliability. At the same time, even the Allison 1000 transmission can experience issues from time to time. When this happens, you might be looking for a transmission repair or replacement; however, you should consider going with a remanufactured Allison 1000 transmission instead. That is where our team can assist you.
