Allison Transmission, previously a division of General Motors, is one of the world leader in automatic transmissions. This US company produces a complete range of automatic electronically controlled transmissions for all on-highway and off-highway applications. Most of the current production is governed by WTEC (World Transmission Electronic Controls) which provides the smoothest shift pattern in the industry. Since its introduction in 1991, WTEC and the WT series (now called the 3000 and 4000 Series) have undergone successive improvements ensuring that Allison remains the world leader in its product. The newly introduced 1000 and 2000 series are dedicated for relatively smaller vehicles and have already proven to be a benchmark in performance and reliability.
