The inaugural 1986 model year Comanches could be equipped with one of three engines: AMC's 2.5 L four-cylinder as standard, with General Motors' 2.8 L V6 or Renault's 2.1 L I4 turbo diesel available as options. In base trim the four-cylinder engine was backed by a four-speed manual transmission, with either a five-speed manual or three-speed TorqueFlite A904 automatic built by Chrysler as an option. The V6 engine was available with either the five-speed manual or the automatic, while the turbodiesel was only available with the five-speed.
