TorqueFlite - Front-wheel Drive Transaxles

Front-wheel Drive Transaxles

The A404, A413, A470, and A670 are front wheel drive transaxle derivatives of the A904 Torqueflite.

In the late 1970s, Chrysler designed the A404 TorqueFlite three-speed automatic transaxle for its front wheel drive Dodge Omni and Plymouth Horizon subcompact cars. This transaxle would be upgraded in the 1980s into the A413 and A670 units, which were progressively heavier-duty, for Chrysler's K-cars and their derivatives, including the minivans. The four-speed Ultradrive electronic four-speed automatic transaxle would eventually replace it, but the three-speed lasted for more than a decade after the 1989 debut of the four-speed unit.
