The use of such a component as a gearbox in the transmission line allows you to regulate the relationship between engine speed and the speed of rotation of the vehicle's drive wheels, ensuring a sufficiently high output of the power unit in almost any vehicle operating conditions.
Smooth transmission of torque from the crankshaft to the primary shaft of the manual gearbox (MT) is ensured by the clutch assembly, the design and operating principle of which are discussed in Chapter Suspension and steering of this Manual. Sequential gear shifting during changes in vehicle speed is ensured by using a multi-stage gearbox in the gearbox. The gear ratios of each of the five stages of the manual gearbox ensure maximum efficiency in transmitting the engine power to the drive wheels of the vehicle. In front-wheel drive models, the gears of the input shaft of the gearbox transmit the engine torque to the gears of the secondary shaft, which is usually located slightly below and to the side of the input shaft. The gears of both shafts of all stages of the forward gears of the manual gearbox are in constant mesh, but continue to rotate freely on bearings until the clutch and corresponding synchronizers are engaged. When shifting from one gear to another during movement, some gears are sequentially released and others are locked on the shaft. The gears are locked and released by the clutches rotating between them and the shaft and equipped with stoppers. In modern gearboxes, the shift stages of all forward gears are synchronized. Friction elements of synchronizers ensure smooth engagement of the corresponding gears with the shaft with preliminary alignment of the revolutions of the toothed locking clutches.
Due to the complexity of the design of the manual transmission, the lack of commercially available replacement internal components and the need to use special equipment, the authors of this Guide do not recommend that car owners perform major repairs to the gearbox themselves. Repairing the gearbox in a car service workshop is a fairly expensive operation, so you should consider alternative options for replacing the failed unit with a new or refurbished one. Any useful information on repairing and replacing the transmission can be obtained at Mitsubishi service stations. Regardless of the chosen method of troubleshooting (repair or replacement), independently dismantling the gearbox from the car will significantly reduce material costs.
In view of what has been said in this Part of the Chapter, the reader is offered only a description of the process of performing such procedures, which are within the qualifications of the average amateur mechanic, as general adjustment of the gear shift drive and removal/installation of the manual transmission assembly.
