For the 2007 model year the TRX420 was only available in four configurations being either 2WD or 4WD and shifting with a manual foot shift or using Honda's Electronic Shift Program (ESP). However, in 2008 Honda introduced the TRX420FA (4WD Automatic) also known as the Rancher AT, as well as electronic power steering. Although the previous ...
An AMT functions in the same way as older semi-automatic and clutchless manual transmissions, but with two exceptions; it is able to both operate the clutch and shift automatically, and does not use a torque converter. Shifting is done either automatically from a transmission control unit (TCU), or manually from either the shift knob or shift ...
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 ...
A power shuttle is an additional unit used in transmissions and is generally used in agricultural tractors.While the vehicle is moving forwards, the driver can pull a lever that makes it stop and go backwards at the same speed.
After the shift is completed, the engine torque i.e., load needs to return to the level prior to the shift to continue accelerating. To avoid a hard shock reaction on the chain drive, stand-alone modules can activate the cut cylinders in a staggered, controlled manner. To achieve this at least two separate control channels are required.
Synchronized downshift rev-matching system (SynchroRev Match) is a technology invented by Nissan for use on the Nissan 370Z.In combination with the Electronic Control Unit (ECU) and various sensors, the engine electronically blips the throttle for the driver during both downshifts and upshifts to allow for better and smoother shifting, and improved handling.
Powershifting, also known as full-throttle shifting or flat-shifting, is a method of gear shifting used with manual transmissions to reduce the time where the driving wheels are not powered. Unlike during a normal gear change, in a powershift the driver does not let off the accelerator.
A transmission control unit (TCU), also known as a transmission control module (TCM), or a gearbox control unit (GCU), is a type of automotive ECU that is used to control electronic automatic transmissions. Similar systems are used in conjunction with various semi-automatic transmissions, purely for clutch automation and actuation.
