The 1941 Chrysler M4 Vacamatic transmission was a two-speed manual transmission with an integral underdrive unit, a traditional manual clutch, and a fluid coupling between the engine and the clutch. [51] [52] [53] The two-speed transmission had "high" and "low" ranges, and the clutch was used when the driver wanted to switch between ranges. For ...
The new (as of 2010) Shopsmith Mark 7 uses a computer-controlled motor that offers more power, greater speed range, reversibility and easy conversion to 220 V. An injury suffered by the user of a Shopsmith gave the Supreme Court of California the opportunity to create the modern rule of strict liability for defective products in 1963. [4]
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 ...
General Motors provided a fix for "Noise #1" but stated that "Noise #2" was a characteristic of any car equipped with a manual transmission and that a similar noise could be repeated by lugging the engine. The remedy for "Noise #1" was to overfill the transmission with Saturn Manual Transmission Lubricant from the stock 1.8 quarts to 2.6 quarts.
The driver often does not have full control of the gear selection, as most manumatic modes will deny a gear change request that would result in the engine stalling (from too few RPM) or over-revving. Some transmissions will hold the requested gear indefinitely, while others will return to automatic gear selection after a period of time.
The PTO was a competitive advantage for IHC in the 1920s, and other companies eventually caught up with PTO implementation. Inside the transmission, the exact point along the gear train where the power is taken off determines whether the PTO can be run independently of vehicle travel (ground speed). Early PTOs were often taken off the main ...
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.
