TORQUE SPECIFICATIONS CHART
Torque Demand
The torque demand downshift occurs (automatically) during part throttle acceleration when the demand for torque is greater than the engine can provide at that gear ratio. If applied, the transmission will disengage the torque converter clutch (TCC) to provide added acceleration.
Torque Converter Control
Based on output rpm signals, signals from the engine control unit (engine rpm and throttle opening) and vehicle speed, a smooth engagement is carried out through linear control of the torque converter clutch (TCC) solenoid. Also, the slip rate is detected by adding input rpm signals and slip control is carried out.
- Engagement Control - control is carried out using a TCC solenoid. The TCC solenoid is linearly turned ON and OFF. The clutch inside the torque converter is operated and the pump impeller and turbine runner are connected. Through this the engine and the transaxle are coupled and engine output is connected directly to the transaxle, eliminating transaxle loss and enhancing fuel economy
- Slip Control - control is carried out using a TCC solenoid. The TCC solenoid is linearly turned ON and OFF and the clutch within the torque converter is operated outside of the engagement range. The clutch slides without being in a completely coupled condition, increasing transaxle efficiency and enhancing fuel economy.
Torque Converter
The torque converter transmits and multiplies torque by means of automatic transmission fluid inside the torque converter. The torque converter is composed of the following
- Converter case
- Pump impeller assembly
- Turbine assembly
- Stator assembly/one-way clutch
- Lock-up clutch
In addition, the use of the lock-up clutch is intended to improve fuel economy as a direct coupling between the engine and the transmission.
The standard torque converter components operate as follows
Scheme 1
- Rotation of the converter housing and impeller sets the fluid in motion.
- The turbine reacts to the fluid motion from the impeller, transferring rotation to the geartrain through the input shaft.
- The reactor redirects fluid going back into the impeller, providing for torque multiplication.
- The clutch and damper assembly dampens powertrain torsional vibration and provides a direct mechanical connection for improved efficiency.
- Power is transmitted from the torque converter to the planetary gearsets and other components through the input shaft.
Fluid Leakage in Torque Converter Area
Leakage at the front of the transmission, as evidenced by fluid around the torque converter housing part of the case, may have several sources. By careful observation it is possible, in many instances, to pinpoint the source of the leak before removing the transmission from the vehicle. The paths which the fluid takes to reach the bottom of the torque converter housing are shown in the illustration. The 5 numbers in the illustration correspond with the 5 flow path steps.
