Gear oil is a lubricant made specifically for transmissions, transfer cases, and differentials in automobiles, trucks, and other machinery. It has high viscosity and usually contains organosulfur compounds .
Via the onboard computer and electronic clutch, the car automatically selects the appropriate gear based on speed and gradient information. An MMT car limits the highest gear selectable, if the gradient is steep. L and 2 gear in a full automatic: The L and 2 gear in automatic can be simulated in an MMT car by either using E1/E2 or M1/M2.
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 ...
Automatic transmission fluid. Automatic transmission fluid (ATF) is a hydraulic fluid that is essential for the proper functioning of vehicles equipped with automatic transmissions. Usually, it is coloured red or green to differentiate it from motor oil and other fluids in the vehicle. This fluid is designed to meet the unique demands of an ...
It is the equivalent to D in a fully-automatic transmission. The gearbox in an AMT car is a manual gearbox, instead of one with a torque converter as in a traditional automatic transmission. M-downshifts a gear in a sequential fashion, from M5 (M6 in 6-speed AMT cars) to M1. M+ up-shifts a gear in a sequential fashion, from M1 to M5 (M6 in 6 ...
This unit was an early semi-automatic transmission, based on the design of a conventional manual transmission, which used a servo-controlled vacuum-operated clutch system, with three different gear shifting modes, at the touch of a button; manual shifting and manual clutch operation (fully manual), manual shifting with automated clutch ...

The other disadvantage of Roto HydraMatic was the extreme oil pressures in the small 8" fluid coupling, which caused transmission leaks. All HydraMatic transmissions suffer some shift quality with today's ATF fluid. The original "Type A" fluid that these transmissions take is available only at O'Reilly Auto Parts.
