Over 1 million of these highly-reliable and durable transmissions have been 
manufactured at Allison's Indianapolis, Indiana campus since 1999.  
Co-production capabilities of the 1000 and 2000 Series transmissions at the 
Chennai plant and in Indianapolis help Allison expand its global footprint as 
well as its presence in India. 

"Our growth outside North America will be facilitated by our established 
relationships with OEMs worldwide, and operations such as our Chennai 
multi-purpose facility," said Lawrence E. Dewey, Chairman, President and CEO of 
Allison Transmission.  "Markets outside North America represent a growth 
opportunity for Allison where we are strengthening our presence and we believe 
opportunities for increased market share exist."  

Allison Transmission's multi-purpose Chennai operation has been manufacturing 
high-quality precision vehicular drive train components for nearly two years 
and has served as a transmission Customization Center for almost a year.  
Allison Customization Centers around the world configure transmissions to a 
specific OEM's requirements prior to delivery which reduces their assembly 
costs and shortens vehicle build times.  

Over a two-year period, the Chennai facility earned the right to produce the 
Allison 1000 and 2000 Series transmissions by demonstrating the ability to meet 
Allison's global best-in-class manufacturing practices.  During this timeframe, 
the Chennai plant was also awarded two of India's most prestigious Golden 
Peacock National Awards (GPNA); the first one in 2011 for Occupational Health 
and Safety and the second GPNA in 2012 for Total Quality in the Automotive 
Sector. 

Allison Transmission is one of the most recognized brands in the industry as a 
result of performance, reliability, quality and fuel efficiency.  It is 
estimated that globally, in 2011, Allison Transmission sold 62 percent of all 
fully-automatic transmissions in the end markets it serves.
