Volvo AW70 Series Transmissions
The AW70 was a 4 speed fully automatic transmission used in the Volvo 240, 740 and 940 series cars starting from 1982 up to 1997 with the end of production of the 940. From the 1989 model year a lock-up torque converter was offered which changed the designation to AW70L. Was originally used in the US specification 1982 Volvo 240 with the B21F engine, as well as in 1983 with the B23F engine. Did not see worldwide usage until 1984 in certain 240 series cars. Some of the 1985-87 B230F-equipped 740's came with a ZF-made gearbox (designated by a gearshift labeled "P R N D 3 2 1"). The AW70 (gearshift labeled "P R N D 2 1" with a side-mounted overdrive lockout) is widely considered significantly more reliable than the ZF transmission.

Famous quotes containing the word series:
“The professional celebrity, male and female, is the crowning result of the star system of a society that makes a fetish of competition. In America, this system is carried to the point where a man who can knock a small white ball into a series of holes in the ground with more efficiency than anyone else thereby gains social access to the President of the United States.”
—C. Wright Mills (1916–1962)
