Abstract
Detroit Diesel Allison introduced it's first electronic controlled transmission, the DP 8000 series transmission, in 1971 with the discrete lope shift pattern generator (SPG). In 1983, a new state-of-the-art digital electronic control option called ATEC (Allison Transmission Electronic Control) was offered on the V 730 series transit coach transmission. ATEC was introduced to the HT 700 series transmission including the CLBT 755 series off-highway transmissions in 1984.
In January 1986, the ATEC system replaced the current SPG electronics across the board on 5, 6, 8, and 9000 series off-highway transmissions. ATEC provides greater capability and increased reliability at a reduced cost over the SPG electronics. The ATEC system is currently in a field test program that will continue through the first year of production to monitor its reliability improvement over the SPG system. Controlled testing to SAE standards have quantified fuel economy and productivity gains with ATEC.
