Pump Assembly and Transmission Fluid Filter
This transmission has a gear type pump that supplies transmission fluid pressure to the hydraulic system.
The inner (drive) gear is turned by the torque converter hub.
The transmission fluid pump has the following parts:
The transmission fluid pump draws transmission fluid from the sump area, formed by the transmission fluid pan, through the transmission fluid filter, which is installed into the intermediate plate portion of the pump assembly and sealed by a rubber seal. A magnet attached to the transmission fluid pan collects any metallic material in the transmission fluid.

Transmission Fluid Level Indicator
A removable dipstick-type fluid level indicator is located on the right front area of the transmission case. It is held in by an external fluid fill plug. The transmission fluid level indicator is removed with the transmission fluid fill plug. The transmission fluid level indicator is removed from the fill plug to check the transmission fluid level.
The transmission fluid level is correctly checked when the transmission is at normal operating temperature, 80ºC-85ºC (175ºF-185ºF), and the vehicle is on a level surface.
The transmission fluid level indicator has 2 areas for the fluid level, a crosshatched (labeled A) area and a dotted (labeled B) area. Use the crosshatched area when checking the transmission fluid level. The correct transmission fluid level is at the upper level of the crosshatch marks on the transmission fluid level indicator.

Main Control Assembly
The hydraulic system of this transmission includes the fluid pump, a main control assembly and fluid passages in the transmission case and center support to apply the clutches.
The main control assembly has an upper valve body assembly, a separator plate and a lower valve body assembly. The lower valve body assembly has 7 solenoids to control the valves in the main control.
TheTurbine Shaft Speed (TSS), Output Shaft Speed (OSS), Transmission Range (TR) and Transmission Fluid Temperature (TFT) sensors are all part of the main control assembly leadframe.
