The transmission control solenoid communicates to a car when it is time to shift gears, if the car has an automatic transmission. If the shifting in the car's engine is balky or has other problems, the issue is likely an error with the control solenoid. Because a fairly sophisticated measurement of hydraulic pressure is necessary to operate the transmission, a solenoid that loses sensitivity to this factor is headed for repair or replacement.Know More
Even with modern electronics governing transmissions, the operating principles that they follow are still mainly hydraulic, requiring a more precise control on the pressure. Older designs for automatic transmissions just use one line with a pressure control solenoid, adjusting pressure throughout the whole transmission. Newer designs require multiple pressure control solenoids, sometimes permitting the solenoids to apply exact pressure controls. It is the shift pressure that affects shift quality; if there is too much pressure, the shifting gets rough, but if there is not enough pressure, the clutches overheat.
If the shifting shows signs of problems, take the car to a certified mechanic to have the troubleshooting codes of the engine checked. Often that is the only clear sign of a problem until the power steering simply gives out, so be proactive. Regular maintenance and inspection can aid in the early detection of mechanical issues and save money on potential repairs.Learn more about Transmission
A CVT, or a continuously variable transmission, is an automatic transmission that replaces conventional gears with variable-diameter pulleys, thus avoiding the need to shift between gears, since the transmission is able to continuously vary its ratio.Full Answer >
A multitronic transmission in a car combines certain aspects of a manual transmission with the convenience of an automatic transmission. It is a type of continuously variable transmission (CVT), which provides more power with an increased fuel economy. Car manufacturer Audi developed the multitronic transmission with a link-type chain, and it was manufactured by Luk.Full Answer >
The only way to convert an automatic transmission to a manual transmission is to completely replace the automatic transmission assembly of the car with a manual transmission. This procedure may be difficult or impossible on some vehicles depending on the model and design.Full Answer >
When transmission fluid is low, the transmission tends to jerk or slip when changing gears. The vehicle may also speed to high revolutions per minute while in neutral or without the vehicle speeding up or spontaneously slip out of gear. A burning smell is another sign that transmission fluid may be low.Full Answer >
