Consequently, the transmission’s operation will be affected, as it uses pressurized transmission fluid to move its mechanical components. If there isn’t enough of it, the transmission fluid will overheat, which affects its hydraulic properties. Yes, the automatic transmission will likely have shifting issues or even start slipping if the fluid level is low. Hopefully, the problem is related to a simple issue that can be resolved quickly. The longer you let the issue continue, the more damage might occur to the transmission. In many cases, prompt attention can alleviate larger transmission problems down the road.
SHIFT SOLENOID HOW TO
If you see a code that you don’t know how to resolve or you are unsure why the transmission is acting up, it’s best to get professional guidance. Contact A ProfessionalĮven if you are a skilled mechanic, you might encounter a problem that is over your head. Whatever code you see, it’s possible to do some research online and hunt down the trouble for a quick fix. For example, you might see a P0606 or P0113 code if there is an issue with the PCM. You can read these codes and learn more about the problem with an OBDII scanner.Įach vehicle uses different codes, although there are some that are universal. When there is a fault in the car’s computers, an error code is set. RELATED: Transmission Fluid Color Chart (5 Different Colors) 2. However, if the fluid is black or dark brown and has a burnt smell or metal shavings included, you could be looking at larger problems. As it gets older, it starts to turn brown, indicating it’s time for a transmission fluid flush. If the fluid is good, it will be a red-pink color. The color of the fluid offers a lot of information about the health of the transmission. While you are checking how much fluid there is, be sure to also check the condition. If the levels are low or below the fill line, it’s time to add some fluid. Make sure you wipe it off and put it back in for a more accurate reading. Unless your vehicle has a sealed transmission, you will be able to pull out the dipstick and read the levels. The first step when you are having any trouble with your automatic transmission is to check the fluid. What to Do When Auto Transmission Won’t Shift 1. The vehicle might even go into the Limp Mode until the problem is resolved. It’s common to see the Check Engine Light and experience erratic shifting patterns. In this way, it acts as the system’s brain.Īs the PCM starts to fail, you may notice other symptoms as well. The PCM or TCM is responsible for controlling the gearbox. When the PCM or TCM fails, the transmission performance is degraded. It can also lead to trouble shifting into a particular gear. It includes vital components, such as a stator and a turbine.Īny of the parts in the torque converter can fail, leading to a slipping transmission. The torque converter is responsible for engaging and disengaging the transmission from the engine. RELATED: 7 Symptoms of a Bad Shift Solenoid 2. The shift solenoids are most often reached by removing the valve body, which is done by removing the transmission oil pan of your car, but in some cases, you have to remove the transmission completely and take that transmission apart. If one of these fails, it can cause shifting issues with any gear, including 3rd gear, so it is therefore very possible that a bad shift solenoid is to blame. Inside the transmission, there are several shift solenoids that are responsible for changing the gears automatically for you when the TCM decides to do so. Following these guidelines can ensure the transmission remains in optimal health.
SHIFT SOLENOID MANUAL
Check your vehicle owner’s manual to find out how often the transmission fluid should be replaced. It can also damage the transmission permanently if it isn’t flushed and replaced promptly. When the transmission fluid gets old, dirt and debris begin to build up in it.ĭegraded transmission fluid makes it much more difficult for shifting to occur normally. It operates much like motor oil, except it’s designed specifically for the transmission. Transmission fluid is needed to lubricate the gears and moving parts located inside. Here is a more detailed list of why your transmission won’t shift into 3rd gear: 1. However, the transmission could also be struggling because of a bad torque converter, a faulty PCM or a damaged shift solenoid that needs to be repaired. Issues with shifting the automatic transmission to 3rd gear often relate to degraded transmission fluid. Conclusion Causes of Transmission that Won’t Shift into 3rd Gear
