The transmission may be the most complicated piece of machinery in your car, van, pickup or 4×4 truck. It is also the most fascinating and intricate. The transmission handles a myriad of fluids, stresses, strains and is a demonstration of a branch of physics called thermodynamics.
MANUAL TRANSMISSION REPAIR IN OCEANSIDE, CA
Your manual transmission contains three basic shafts: the input shaft is connected to the clutch where the clutch is drawing power from the engine; the output shaft is connected to the axle or drive shaft depending on your automobile’s set-up; and a counter or layshaft where the weights and ratios change that acts as a mediator between the input and output shaft. The shifter is located in the layshaft.
When your car is in neutral the gear shift moves side to side loosely. As soon as you put your car into first gear, the input shaft moves a small gear to the countershaft to the smallest gear on the output which provides the most torque. After selecting the gear, power goes to differential and differential is the final drive.
Torque decreases as you upshift. As it moves to the highest gear, it sets the input shaft to the splines of the clutch disc which is being turned by the motor’s power.
AUTOMATIC TRANSMISSION REPAIR IN OCEANSIDE, CA
Similar to the manual transmission, the torque is derived from the head end of crankshaft. In contrast, the crankshaft is connected to a donut shaped part called a torque converter containing fan like blades that spin, one set pushing hydrofluid against another. The hydraulic clutch converters take these hydraulic signals and control the shifting of gear unit and locking torque converter in accordance with corresponding hydraulic pressures. Behind the torque converter are transmission gears, to save space little gears are mounted behind larger ones. There are usually three such planetary gears including overdrive and one to reverse. Each shift of the gears is controlled by a shift valve; the gears shift change depending on speed, the road, and load conditions.
DRIVETRAIN REPAIR IN OCEANSIDE, CA
The drivetrain controls both the power and torque derived from the engine to turn the wheels. A ratio gearbox allows the engine to function at a range of RPMs at any road speed, by adjusting the ratio between power and torque.
The drivetrain contains both the vehicle’s transmission and the differential. Whereas the transmission allows adjustment to the gear ratio, the differential allows the drive wheels to rotate at different speeds. Sometimes these are combined in a front wheel drivetrain layout in what’s called a transaxle. According to ZontMOZ, “These are usually found on front wheel drive cars, but are also used on mid- and rear-engine cars. Some exotic cars have their engine in the front, and a transaxle in the rear of the car for better weight balance.”
