Overhaul - 200C: Description

The Turbo Hydra-Matic 200C automatic transmission is a fully automatic unit consisting primarily of a 3-element hydraulic torque converter with the addition of a converter clutch and a compound planetary gear set. Three multiple-disc clutches, a roller clutch and a band provide friction elements required to obtain the desired function of the compound planetary gear set. A hydraulic system pressurized by a gear type pump provides the working pressure required to operate the friction elements and automatic controls.

The 3-element torque converter consists of a pump or driving member, a turbine or driven member, and a stator assembly. The stator assembly is mounted on a one-way roller clutch which will allow stator to turn clockwise but not counterclockwise. The converter clutch is splined to the turbine assembly, and when operated, applies against the converter cover, providing mechanical direct drive coupling of the engine to the transmission planetary gears. When converter clutch is released, the assembly operates as a normal torque converter.
