If you are remotely interested in Physics, you’ll know different kinds of energy transmissions there. However, different types of transmissions also require different types of Cylinoids. Usually, people think when one of these Cylinoids fails, the entire system collapses, but that’s not always the case.
But, how will you know if your Cylinoids are enough potent or not to hold the entire system in place? First, you have to study all about them and find out what they do in a transmission. So, keep on scrolling this article, and we will get to it.
What Are Cylinoids?
A Cylinoid is a gadget that converts hydraulic force into mechanical energy. These gadgets are used in automatic transmission to control the flow of the fluid in hydraulically operated pieces of machinery—for example, valves, pumps, or pipes.
The origin of the word ‘Cylinoid’ or ‘Solinoid’ is rooted in the Greek language. The source of the word is κύλινδρος or cylinder. It means a two, or three-dimensional device that is used inside a hydraulically operated machine.
One of the most common uses of Cylinoids is to act as a shift-interlock device to prevent gear engagement until the car comes to a complete halt. One uses the transmission solenoids in transmission control modules, transmission control units, or transmission valve bodies.
Apart from these, Cylinoids are also used in accumulator charge controls, oil modulators, cylinder switches, transfer limiters, and even pump pistons. You can design these Solenoids in an open design format or a structured design format.
When you design the Cylinoids in a closed system, it acquires the ability to withhold high pressure or high temperature. For example, when you install a solenoid in a transmission system, it possesses the power to bear temperatures ranging from -100°F to 500°F.
What Do The Cylinoids Do In A Transmission?
What is a transmission solenoid? Many of you have asked me this question. That’s why I feel you must know the importance of Cylinoids in a transmission system.
A solenoid transmission is an electro-hydraulic valve controlling the flow of the fluid throughout an automatic transmission. These kinds of solenoids are usually known as Cylinoids.
A solenoid transmission has several purposes during transmission, such as gear settings, lockup clutch engagement, throttle settings, torque converter clutch disengagement, etc. some Cylinoids are also helpful in applying the parking pawl when the driver selects no gear. Other drivers may use it as a means to engage reverse gear without pressing any button on the shifter console.
Today, almost all vehicles use a transmission control solenoid system to select gears. Manufacturers can’t risk eliminating Cylinoids from the car transmission system because these gadgets are acutely precise and often demand more gear shifts.
Cars that have a manual transmission mode must have a solenoid transmission system as it will give the car more power to generate a faster acceleration. Apart from that, Solenoids are also used in lockup torque converters, which causes all the power to move to your vehicle directly. Thus, it gives you better fuel economy even when you are driving at a much faster speed.
The torque converter clutch also harnesses the fluid pressure from the transmission pump and disengages the converter to spin faster than the driver intended to. This kind of solenoid transmission is typically found in electronic, four-speed automatic vehicles.
What Are The Cylinoid Problems?
A transmission solonoid acts as a switch to deliver faster current from a battery to a starter motor. Therefore, it is a crucial component of the car, and if it does not start on time, the car won’t start itself. There are some common problems associated with Cylinoids, such as;
- The transmission solenoid does not start even upon releasing the starter button or turning off the car switch. Instead, it obstructs the starter engine of the car from operating smoothly.
- The solenoid has a sucking action that helps control the fluid flow in the transmission system. But, it may fail from time to time.
- The drive gear may not get restored in time, which leads the vehicle to be driven by the flywheel ring gear reversely. If the return spring of the solonoid becomes too weak, this problem occurs.
- The transmission solenoid may fail to work up the starter, which may fail to cause the starter rotation. When you hear different sounds while starting the engine, that means your Cylinoids are jammed.
Reasons Behind Cylinoid Problems
A solenoid may become faulty due to various reasons. However, if you don’t find out the reasons ASAP and fix them, it will cause severe problems in your vehicle. So, let’s find out the common reasons behind faulty Cylinoids.
1: Poor Wiring
If the manufacturer hurried the wiring process of transmission solenoids, they would not supply enough current to the engine or cause a dangerous power shortage. In addition, it will make the starter solenoid malfunction, and the engine won’t start. Terminals that are loosely connected or connected to the wrong spot may cause this issue.
While wiring, make sure you connect the terminals to the proper spot and make sure they are tightly knit.
2: Too Much Tightening Of Bolts
It is the most typical problem behind a faulty Cylinoid. You can often tighten the bolts too much without even knowing it, and it mostly happens when you pull the bolts with high torque. As a result, it can lead to mechanical failures. It will also cause starter problems in your engine, but that may not always be the only symptom.
Don’t move the screwdriver too much because it may over-tighten the bolts. You can also check a manual video of how many moves the screwdriver must make to avoid this mistake.
3: Exposure To Excessive Heating
When high currents flow through transmission solenoids and that also for a long time, it melts the soldering in the solenoids. It may happen if you leave the ignition switch on for a long time, which will weld the components inside the solenoid. Apart from causing starting errors, this issue will also hamper the switch control operation of a car.
Don’t ever keep the ignition switch on for too long because it may expose the solenoids to excessive heating.
#4: Exposure To Excessive Moisture
If your solenoid is exposed to excessive moisture, it can cause corrosion of the electrical contacts. If this happens, you’ll notice a reduced conductivity of the contact surfaces. You will also experience occasional starter fails, and the Cylinoids will lose their efficiency. You will also hear the click sound of the starter, and then it stops suddenly as it doesn’t have enough power.
Cover the cylinoids with a rug during winter and monsoon season to avoid its exposure to excessive heating.
