As described above, impelling losses within the torque converter reduce efficiency and generate waste heat. In modern automotive applications, this problem is commonly avoided by use of a lock-up clutch that physically links the impeller and turbine, effectively changing the converter into a purely mechanical coupling. The result is no slippage ...
Saab's Sensonic system was electro-hydraulic, using an electric motor or solenoid connected to a hydraulic clutch actuator, whereas Ferrari's Valeo system was electro-mechanical, using an electric motor or solenoid, connected to the mechanical clutch system. [8] [9] [10] Similar TCU or GCU systems are used in racecars with paddle-shift ...
The SM465 features dual provisions for power take-offs. The 1988-91 versions have an aluminum top with improved shift feel. The 1985 and newer versions utilize a hydraulic clutch release, replacing a mechanical linkage in older versions. A common wear factor in the form of abuse leads to having to manually hold the gear selector in third.
Automatic clutch plus a torque converter. Used in the Citroën GS and Citroën CX. Originally called Convertisseur in GS models. 1991–1993: Ferrari Valeo: Automatic electro-mechanical clutch. Used in the Ferrari Mondial t. [77] [78] 1992–1998: RUF EKS: Automatic electro-hydraulic clutch. Used in the Ruf BTR [79] and Ruf BTR2. 1993–1998 ...

Automated manual transmissions can be semi-automatic or fully-automatic in operation. Several different systems to automate the clutch and/or shifting have been used over the years, but they will generally use one of the following methods of actuation for the clutch and/or shifting: hydraulic or electro-hydraulic actuation, [12] electro-mechanical, [13] pneumatic, [6] [14] [15] electromagnetic ...
Roto's disadvantage was the 2-3 range or 1-2 gear change because it is not only a huge ratio jump from 2-3 range or 1-2 shift from 2.93 to 1.56, but also there is no fluid slippage in the coupling because the coupling drains (four-tenths of a second) to engage or apply the front clutch and so the trans goes to full mechanical connection.
The main components of a parking pawl mechanism are the parking gear, parking pawl, actuator rod, cam collar, cam plate, pivot pin, and parking pawl return spring. The mechanism assembly is designed so that the parking pawl tooth collides and overrides the parking gear teeth (ratchets) until a safe engagement speed for the vehicle is reached.
