While your engine is what propels your car, your transmission is what allows that motion to be converted into more useful actions that make modern driving the convenience that it is today. Without a transmission, vehicles would either be quite slow or nearly impossible to operate at low speeds.

This importance means that transmission problems are a major deal and should never be ignored. Since the transmission is one of the most complex components of a car, you will want to have any issues checked immediately before they cause serious consequences throughout your transmission system. South Brunswick Township, Plainsboro Township and New Brunswick Toyota owners should look for signs of the following problems to ensure that their Toyota will be running as it should be for years to come: 

Low or Old Transmission Fluid

Transmission fluid lubricates all the moving parts inside the transmission case while also absorbing heat energy. Both of these functions reduce the impact heat and friction have on parts. In automatic transmissions, the fluid even acts as a hydraulic actuator to assist in the gear-changing process.

When transmission fluid gets low, things inside the case start to heat up and eventually break down. Drivers will experience sluggish vehicle responses, odds noises or smells and, eventually, dysfunction within the system. Similarly, old transmission fluid that needs to be replaced will not be able to perform its needed functions nearly as well.

Since transmissions are almost completely closed systems, low fluid is often the result of leaks or problems with the case's integrity. Small holes, worn gaskets, punctured seals and ruptured O-rings can all cause transmission fluid to leak and hurt your vehicle's performance. 

Faulty Solenoid

Symptoms of low transmission fluid can also be the result of a damaged or faulty solenoid. This device pumps transmission fluid throughout the system. When it is malfunctioning, drivers may notice nothing at first but gradually experience transmission issues as their ride continues. Broken solenoids are serious problems and can cause transmissions to overheat if ignored. 

Torque Converter Problems

Your torque converter connects your engine's crankshaft to the rest of the transmission. It also lets the vehicle idle safely without engaging the main drive shaft or any of the gears. When the torque converter is damaged, it will often engage gears when it is not supposed to. Drivers may notice the engine pushing even when they are stopped. They may also hear grinding sounds as the vehicle shifts between gears. 

Grinding Gears or Lurching

Manual transmissions often see worn-out clutch pads, springs and discs. Incomplete shifting either through driver error or system malfunction leads to damaged gears and clutch mechanisms.

Automatic transmissions have it far worse in this category. Rather than problems cau sing damage to one isolated part, they will see a total range of symptoms that can affect every part in the system. Most commonly, gear shifting will be sluggish and performance could be decreased since not every part is engaging as it should. Over time, drivers may notice a sudden jerk or lurching while the vehicle switches from one gear set to the next. This type of problem should be dealt with quickly before something permanently breaks or the entire transmission gives out.
