The primary 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 variable drive pulley assembly |
| • | A variable driven pulley assembly |
| • | A variable drive belt assembly |
| • | Forward clutch piston and clutch assemblies |
| • | Reverse clutch piston and clutch assemblies |
| • | A front differential carrier assembly |
| • | A front differential drive pinion gear assembly |
| • | A control valve body assembly |
The electrical components of this unit are as follows:
| • | A module leadframe, including a transmission fluid temperature (TFT)
sensor |
| • | A TCC pressure control solenoid valve |
| • | A TCC enable solenoid valve |
| • | A line pressure control solenoid valve |
| • | A transmission fluid pressure sensor |
| • | An input and output speed sensor assembly |
| • | A park/neutral position switch |
