The mechanical components of this unit are as follows:
• | A torque converter with an electronically controlled capacity clutch (ECCC) |
This transmission is equipped with an electronically controlled capacity clutch (ECCC). The pressure plate does not fully lock to the torque converter cover. Instead, the pressure plate maintains a small amount of slippage, about 20 RPM, in SECOND, THIRD and FOURTH gears, depending on the vehicle application. ECCC was developed to reduce the possibility of noise, vibration or chuggle caused by TCC apply. Typical apply speeds are 49-52 km/h (30-32 mph) in THIRD gear and 65-73 km/h (40-45 mph) in FOURTH gear. Full lockup is available at highway speeds on some applications. |
• | A drive link assembly |
• | 5 multiple disk clutch assemblies: Second, Reverse, Direct, Coast, and Forward |
• | 2 friction bands: Intermediate/Fourth band and Low/Reverse band |
• | 2 planetary gear sets: Input and Reaction |
• | 3 one-way clutches: 2 roller clutches (Second and Low) and a sprag clutch |
• | A final drive and differential assembly |
• | A control valve assembly |
• | A vane type oil pump |
The electrical components of this unit are as follows:
• | 2 shift solenoid valves |
• | A Torque Converter Clutch Pulse Width Modulation Solenoid (TCC PWM Solenoid) valve |
• | A Pressure Control Solenoid valve (PC Solenoid Valve) |
• | An Automatic Transmission Fluid Temperature (TFT) sensor |
• | 2 speed sensors: Input and Vehicle Speed Sensor |
• | An Automatic Transmission Fluid Pressure Manual Valve Position switch (TFP Valve Position Switch) |
• | An Automatic Transmission (A/T) Wiring Harness |
