Digital Electronic Controls For Detroit Diesel Allison Off-Highway Transmissions 850782
Detroit Diesel Allison introduced it's first electronic controlled transmission, the DP 8000 series transmission, in 1971 with the discrete logic 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 700 series transit coach transmission. Today, the ATEC control is available on all HT 700 series transmissions including the CLBT 700 series off-highway transmissions.
In January 1986, the ATEC system will replace the current SPG electronics across the board on 5, 6, 8, and 9000 series off-highway transmissions. It will offer greater capability and increased reliability at a reduced cost over the current electronics. The ATEC system is currently in a field test program that will demonstrate its reliability improvement over the SPG system.
