An automated manual transmission (AMT) is essentially a conventional manual transmission that uses automatic actuation to operate the clutch and/or shift between gears. Many early versions of these transmissions were semi-automatic in operation, such as Autostick , which automatically control only the clutch , but still require the driver's ...
Made from petroleum with various refinements and additives, ATF is one of the few parts of the automatic transmission that needs routine service as the vehicle ages. The main pump which pressurises the ATF is typically a gear pump mounted between the torque converter and the planetary gear set. The input for the main pump is connected to the ...
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 ...
The speed of the gear change depends on the engine revs. If the engine has more than 5000 rpm and the throttle is pressed more than 60%, the change is faster. The system also has a rev limiter to avoid over-revving (in GTA models this behavior is removed). Downshift is accompanied by automatic rev-matching.
Automatic – once placed in drive (or any other 'automatic' selector position), it automatically selects the gear ratio dependent on engine speed and load; Basically there are two types of engine installation: In the longitudinal direction, the gearbox is usually designed separately from the final drive (including the differential). The ...
In a vehicle with an automatic transmission, the torque converter connects the prime mover to the automatic gear train, which then drives the load. It is thus usually located between the engine's flexplate and the transmission. The equivalent device in a manual transmission is the mechanical clutch.
A direct-shift gearbox (DSG, German: Direktschaltgetriebe [1]) [2] [3] is an electronically controlled, dual-clutch, [2] multiple-shaft, automatic gearbox, in either a transaxle or traditional transmission layout (depending on engine/drive configuration), with automated clutch operation, and with fully-automatic [2] or semi-manual gear selection.
The transmission is also produced in Yantai, China. 6T30 is a recent more compact and lightweight variant used on 1.8 L engine equipped variants of the North American Chevrolet Cruze and Chevrolet Sonic. The 6T40 was still used in those models equipped with the 1.4 L turbocharged engine. GM lists the weight of the 6T30 with fluids at 71.5 kg ...
