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 demonstrates a branch of physics called thermodynamics.
Manual Transmission Repair In Oceanport, NJ.
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, 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 loosely moves side to side. 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. 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.

Similar to the manual transmission, the torque is derived from the head end of the crankshaft. In contrast, the crankshaft is connected to a donut shaped part called a torque converter containing fan like blades that spin, one set pushes hydrofluid against another. The hydraulic clutch converters use these hydraulic signals to control the shifting of the gear unit and locking torque converter in accordance with corresponding hydraulic pressure. 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 depending on speed change and road conditions.
Drivetrain Repair In Oceanport, NJ.
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.”
