This six speed automatic transmission displays durability characteristics required in the truck and bus industries, while serving fundamental roles in improving vehicle performance through a new gear train and a multi disc lock up clutch. Other features include better braking performance, higher torque capacity with less weight, smoother shift quality while attaining high reliability.
The hydraulic control mechanism utilizes direct control of main pressure by use of a linear solenoid.
The primary mechanical components of the transmission consist of the following:
- Three sets of clutch packs
- Two sets of brake packs
- Three planetary gear sets
- Single stage, three element, two phase type torque converter.
- Valve body
- Linear solenoids
- On/Off Solenoids
- Oil Pump
The Transmission Control Module (TCM) is the "heart" or "brain" of the electronic control system and relies on information from various direct and indirect inputs (sensors, switches, etc.) to determine driver demand and vehicle operating conditions. Depending on the vehicle configuration, the TCM may be a standalone module or it may be housed along with the Powertrain Control Module (PCM) in a single module. With this information, the TCM can calculate and perform timely and quality shifts through various output or control devices.
