The military and heavy-duty commercial truck markets require transmissions that are not only capable of heavy loads, rigorous duty cycles, and proven reliability, but must also provide value for the end-user and maintain compatibility with leading-edge technological improvements of engines and other vehicle systems.Duramax \u0026 8.1 Allison Transmission Flush
The HD transmission is one of the latest offerings from Allison Transmission to meet these next-generation needs, according to Senior Project Engineer Timothy Cooney. It is designed to be compatible with the fast-changing electronics capabilities of modern vehicle systems.
These units received electronic controls in the s but can no longer be uprgraded with the control systems necessary for use with future engines and vehicles. The new unit is based on the company's heavier-duty HD World Transmission but has been adapted to the needs of military and commercial markets.
Based on customer needs and company mandates for the new product, requirements included more ratio coverage; additional gear ratios with single transition shifts, without loss of power during shifting; a common transmission sump; accommodation of current rear output retarder and rear cover, the latter to simplify assembly and installations; and provision of mounting pads. These requirements resulted in a decision to modify the HD with an additional gear range and a high mechanical ratio.
The design of the seven-speed HD is substantially similar to Allison's HDexcept for the added gear range. The seventh speed is obtained by adding a fourth planetary gear set and a sixth clutch. This combination provides for a mechanical ratio of 7. In many cases, this allows for the elimination of the low auxiliary range needed in the transfer case. A seventh speed in the HD is obtained by the addition of a fourth planetary gearset and sixth clutch.
The new transmission features second-gear starting because it is anticipated that first-range capability will be needed only for special conditions. The addition of solenoids for the C6 clutch resulted in the need to remove a solenoid used in some configurations for retarder accumulators.
Due to this limitation, HD units equipped with output retarders will not be able to use accumulators.
The HD was released for military and commercial use in earlywith first use in the U. Marine Corp. Production is scheduled to ramp up slowly for the first 18 months, with many other military applications expected to be added by the end of The transmission's first commercial application was in fire crash trucks due to their similarity with the MTVR program. Other commercial applications are expected to include crane carriers, to be added in mid after ramp-up.

Most diesel-powered Type A motorhomes and a fair number of gasoline-powered coaches are equipped with Allison transmissions. Such transmissions have set the industry standard for longevity and reliability, but like any chassis component, they require regular maintenance.
The nine most common Allison motorhome transmissions on the road today range from model MH to model MH. This article serves as a guide for do-it-yourselfers. The first step in determining service requirements is to find the model and serial number of your Allison transmission.
This information typically is available from the manufacturer of the motorhome or the chassis. You also can crawl under the transmission and look for the serial number, which usually is stamped into a steel plate on the right side. Then, go to the Allison website and visit the My Transmission page at www. The bulletin covers a range of transmissions and includes tables based on the series, fluid type, and age of a transmission. Service intervals are separated by vocation type.
If you have a or series transmission, you must know the sump size in order to determine the fluid capacity and filter part numbers. Such transmissions come with either a 2-inch or a 4-inch sump. Determine the size by measuring the cast-aluminum pan that is bolted to the bottom of the transmission housing. Unlike diagnostics, which help with troubleshooting, prognostics proactively prevent problems. Prognostics first appeared in model-year coaches. Prognostics electronically monitor the transmission and interface with the Allison shift pad in the cockpit.
Although previous shift pads displayed error codes and transmission fluid levels, prognostics-enabled electronic controls offer much more, including an oil-life monitor, filter-life monitor, and transmission-health monitor.
With prognostics, the transmission fluid and filters no longer must be serviced solely on a time or mileage basis. Their life is displayed as a percentage that more accurately reflects the condition of the transmission and its serviceable items. To view the filter life, press the buttons a third time. Various other operations are available in prognostics; check the owners manual for the procedure to retrieve additional data from the Allison shift pad.
In older transmissions that still have nonsynthetic fluid, your best bet is to replace it with TranSynd; otherwise, the fluid and filters must be changed more frequently. Two complete fluid changes are needed to purge enough of the nonsynthetic fluid before you can begin the extended service schedules.
Since the introduction of TranSynd, other manufacturers have developed synthetic transmission fluids. For the most current list, visit www.Having trouble finding your part? Let TPI find the part for you. We want to hear from you!

Allison products are specified by over vehicle manufacturers and are used in many market sectors including bus, refuse, fire, construction, distribution, military, and specialty applications. Allison began in when James A.
Allisonalong with three business partners, helped fund and build the Indianapolis Motor Speedway. InAllison's new track held the first Indianapolis mile race. In addition to funding several race teams, James Allison established his own racing team in and quickly gained a reputation for his work on race cars and automotive technology in general.
When World War I began, Allison suspended racing, and the Allison Experimental Company began machining parts, tools, and masters for the Liberty airplane engine — the main power plant used in the US war effort. After the war, Allison entered a car in the Indy and won. It was the last race Allison's team ever entered as he turned his company's attention to aviation engineering.
The company's expertise in aviation was the major factor in General Motors decision to buy the company following James Allison's death in Shortly after the sale to General Motors inAllison engineers began work on a cylinder engine to replace the aging Liberty engines. The result was the V cylinder aircraft engine and it made the company, now known as the Allison Engine Companya major force in aviation. The new division developed a transmission combining range change, steering and braking. Allison designed, developed and manufactured the first-ever automatic transmissions for heavy-duty vehicles including delivery trucks, city buses, and locomotives.
GM-Allison introduced hybrid technology for transit buses in Throughit intends to introduce 16 hybrid models. As ofthere are more than 2, GM-Allison hybrid buses operating in 81 cities in the U. From Wikipedia, the free encyclopedia. Allison Transmission Inc. IndianapolisIndiana.
