US-based Allison Transmission, the largest manufacturer of fully automatic transmissions for medium and heavy duty commercial vehicles and hybrid propulsion system for city buses, has begun production of the Allison 1000 and 2000 transmissions at its Chennai plant. For the last two years the Chennai plant has been manufacturing high-precision vehicular drive train components, while it also has served as a customisation centre for about a year, configuring transmissions to OEM’s specific requirements which help reduce the OEM’s assembly costs as also the vehicle build times. Allison’s Chennai plant has also been awarded two 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.
