![]() Here are some solutions for your reference on how to fix car not changing gears, specifically the third one. What To Do When Automatic Transmission Won’t Shift into 3rd Gear? The vehicle may even go into Limping Mode until the problem is resolved. You often see the Check Engine Light and experience erratic shifting patterns. When the PCM begins to fail, you may also notice other symptoms. In this way, it acts as the brain of the system. These parts are responsible for the gearbox performance. When PCM or TCM fails, transmission performance is degraded. It can also lead to problems when switching to a specific number. It consists of important components, such as the stator and turbine.Īny part in the torque converter can fail, resulting in transmission slippage. The torque converter is responsible for engaging and disconnecting the transmission from the engine. Shift solenoid tubes are most commonly achieved by removing the valve body, which is done by removing the car’s transmission oil pan, but in some cases you have to completely remove the transmission and remove the box. ![]() If either of these fails, it can cause shifting problems with any gear, including the 3rd gear, so it’s most likely a bad shift electromagnet. Inside the transmission, there are several gear shift solenoid coils that are responsible for automatically shifting gears for you when TCM decides to do so. (Photo: AxleAddict) Solenoid gear shift problem Degraded transmission fluid makes normal gearshifts much more difficult. Following these instructions can ensure the transmission remains in optimal condition. It can also permanently damage the transmission if not drained and replaced promptly.Ĭheck your vehicle’s owner’s manual for how often to change the transmission oil. As transmission fluid ages, dirt and debris begin to accumulate in it.ĭegraded gear oil makes normal gearshifts much more difficult. It works just like engine oil, except it’s designed specifically for transmissions. Transmission oil is needed to lubricate gears and internal moving parts. The cooler within the radiator can occasionally leak and contaminate the radiator coolant. > See more: Can Too Much Transmission Fluid be a Problem?Īlso, don’t forget to check the coolant fluid in the radiator. If no leak exists, rinse out the old oil and refill the container. ![]() As a result, your first step in dealing with a stuck gear should be to check the transmission oil.Ĭheck for leaks in the input and output shaft seals, fluid lines, pan gasket, and cooler if the level is low. In fact, low fluid levels are the cause of a number of transmission-related difficulties. ![]() Overheated engine might be the cause of the gear sticking, and a low transmission fluid level is to blame for the transmission becoming overheated. Let’s see what could be the reasons for the car won’t shift gears from second to third. If you ignore the signs for too long, it could lead to a possible failure of the transmission. But, when it fails to do so, there must be an internal hitch affecting the performance. (Photo: DriveSpark) Automatic Transmission Won’t Shift into 3rd Gear: What Are The Reasons?įunctional auto gearbox will shift up, down, and rest upon appropriate commands. Take immediate action when facing problems with shifting gears. In that case, the catalytic converter can touch the side of the valve body area, overheating the transmission and creating metal shavings in the pan. It smoothly glides between the first and second and vice versa, but it just stays in second when you try to push it to the third. It seems that the gear slips into neutral when you push it to the third.Īnother instance could be the automatic transmission won’t shift into 3rd gear at all. The problem could occur in a couple of forms that can be easy to recognize and follow.įirst, you can notice that the transmission shifts into the first and then to second gear but does not move into the third gear. The Signs of Automatic Transmission Won’t Shift into 3rd Gear Such a problem is that the automatic transmission won’t shift into 3rd gear. Upkeep and maintenance of these machines are tricky since the glitch with a tiny component can mess up with the gearbox. A transmission is a complex piece of machinery that runs on lots of complicated mechanisms. ![]()
