Light indicates transmission problem

A warning light on my dash is indicating that I have a problem with my transmission.
Experienced mechanics share their insights in answering this question :
A code scan with an advanced scan tool is required to read the codes from the transmission. The codes will then help diagnosis of the actual problem. A test drive by a technician will also aid in diagnosis. An inspection from a qualified technician, such as one from YourMechanic, can help you determine the cause of your transmission warning light, and recommend the best solution.

It indicates a problem with the transmission. It`s similar to the “check engine” light. Get the codes read to determine the cause. It could be something simple like a speed sensor or something more important.
Lastly, there have been reports of transmission issues with the 2021 Ford Explorer, particularly when shifting between gears or accelerating quickly from a stop. This can cause jerking motions or even stalling out completely while driving if left unaddressed for too long.
OD light flashing indicates a problem with the transmission. The problem could be a transmission mechanical, hydraulic or electrical in nature. Overfilling can cause the fluid to foam and foam in the fluid can cause all kinds of symptoms. Explorers have had transmission issues over the years.
2004 Ford Explorers commonly have transmission problems such as the vehicle hesitates when shifting, lunges forward when engaging and even clunking in reverse. Additional Ford Explorer transmission problems include shifting gears, gears are slipping, or the vehicle will not move.
A transmission light can turn on for several reasons ranging from an overheating transmission and bad transmission fluid to gear change issues. Checking the transmission fluid level and getting regular transmission service can help prevent car issues.
The automatic transmission warning light means there`s an issue with the transmission, possibly the fluid temperature, fluid level, or pressure.
However, in general, it`s probably not a good idea to tow in overdrive because the transmission could overheat and cause damage.
Possible causes of no overdrive include a faulty transmission range switch, valve body, faulty overdrive brake, or faulty ECM. Faults codes should be read out with a scanner, and statuses read.
Because the transmission warning light can come on for a variety of reasons, some of which are significant problems, you should not continue to drive your vehicle with the light illuminated. You (or your mechanic) should diagnose and repair the problem right away to prevent further damage to the vehicle.
Depending on the issue (low fluid is an easy DIY job), most transmission problems can only be properly diagnosed and repaired by a reputable mechanic. Most transmission repairs require specific tools and replacement parts to get them back up to speed.
Normally when automatic transmissions have damaged gears they progressively get worse. Summary: This is a more serious problem and time is very important. Be sure to get your car to a qualified automatic transmission specialist soon.
Bad habits such as parking without the handbrake, changing gears incorrectly, and shifting an automatic transmission before the car comes to a complete stop can cause your transmission to wear out prematurely.
All Explorers come with a five-speed automatic transmission.
The short answer to this question is no, you should not drive with a bad transmission. Sometimes, life happens, and you have to keep driving your vehicle even though you know that it needs to be serviced.
Often (though not always) a faulty transmission will trigger an engine diagnostic code and trip the Check Engine Light to let you know. Same goes if your engine overheats because of a bad transmission. Problems with a solenoid, speed sensor, slippage, and more can cause the Check Engine Light to come on.
RepairSmith offers upfront and competitive pricing. The average cost for Ford Explorer Transmission Rebuild is $3215.
The fuel pump shut-off switch is located behind an access panel in the right rear quarter trim panel, near the liftgate. The fuel pump shut-off switch has a red reset button on top of it.
Third gear either locks the transmission in third gear or limits it to the first, second, and third gear ratios.
For most driving situations, you should leave it on. This allows your vehicle to use all of its available gears including the highest ones. Overdrive maximizes fuel economy and keeps NVH (noise, vibration, harshness) at a more tolerable level. There are no downsides to having it on.
The Vehicle Speed Sensor measures vehicle speed. When it fails the transmission can stop shifting or shift late and harsh. A bad VSS may also inhibit overdrive and the converter clutch.
A car has two speed sensors: the ISS and the OSS, working together to show the transmission data to the car`s powertrain module. The ISS sensor monitors the input shaft`s speed. If these sensors get misaligned, the operation of the transmission system will be affected.
Problems Battery Corrosion Cause on Transmission

Many times, the problems will happen intermittently because of how the electrical system works. So the transmission will show signs of problems and then will work fine, making it hard to know that your transmission could be failing if the battery isn`t taken care of.

Don`t buy Ford Explorers that were made between 2002 and 2006 because their transmissions are prone to problems. Other year models are safe.
Ford`s PowerShift dual clutch transmission was used in 2010. Vehicles impacted are the Ford Fiesta (model years 2011-2016) and the Ford Focus (model years 2012-2016) equipped with a PowerShift transmission.

Abs light, emergency brake light, steering wheel assist light, engine light, EPC light, traction control light
ANSWER : Hello, thank you for writing in. The vehicle does utilize a lot of the same sensors for these systems. Are there any other codes that are coming up when this code appears? If so you will want to take these into consideration when processing the repair and making a diagnosis. The module may be bad, and replacing it should fix the problem. The lights should turn off once the main computer recognizes the new module and the sensors sync up. If you believe the sensors need to be cleaned you may do so. Do as minimal as possible to make sure you are not damaging the sensor or disrupting the wiring inside. A bad connection would make the lights stay on. With so many lights that are effected by the module being illuminated, the module is likely bad or does not have a connection. Check the connection first and then resort to replacing the unit.

Electrical problems after upgrades
ANSWER : Hi there. From the description you have provided, all of your vehicle’s electrical problems began with the "upgrades". Unfortunately this could be a can of worms to repair. Assuming, you had a qualified technician install the vehicle’s radio and lighting upgrades and all was fine after the installations. This would lead me to believe your vehicle has several problems. The first place to look would be fuse(s) for the inoperative components. Next, to look for shorts to power the components staying on. If you can find the problem yourself, I recommend having your vehicle’s electrical problems diagnosed and repaired by a certified technician, like one from YourMechanic.

No dash lights, back right tail light is out, no parking lights. Brake lights work though as does head lights.
ANSWER : Hi there. In many cases, when you have electrical problems like you’re describing, it’s caused by multiple electrical component failure. It’s likely that a few electrical relays are not working; especially if you have systems that utilize the same components (such as your brake light and tail lights). I would recommend having a professional mobile mechanic come to your location to complete an electrical problems inspection first, so they can pinpoint what is damaged and recommend the right repairs.

The Battery Light is on and the lights and power mirrors are not working – 2002 Mercedes-Benz C320
ANSWER : Hi. If the Battery Light is on, this an indication that either the battery is bad, the alternator is not charging properly, or both of them are bad. Low battery voltage will cause the car to do abnormal things like have no headlights. There are other things that can cause headlights to not work as well, for example, a blown fuse, broken headlight relay, or, the most common cause, blown headlight bulbs.

I suggest you have a certified technician, such as one from YourMechanic, come to your location to determine why the Battery Light is on and suggest the necessary repairs.

ABS light on, ESP light on,Traction OFF light on, engine light on, rides perfectly OBDI reads only Front Right Wheel Speed Sensor
ANSWER : If a faulty component is still in place, the fault codes will return almost immediately after clearing them. ABS, ESP, and traction control systems all rely on input from wheel speed sensors to determine as the name implies, the speed of each wheel. When a wheel, or wheels are spinning faster than others due to wheel slip or the vehicle is sliding, the ABS and ESP systems can reduce throttle input as well as apply braking to an individual wheel or all of them if needed. With a wheel speed sensor fault code stored, these systems cannot determine the rate that all 4 wheels are spinning and sets a fault. That is why the abs/esp light is on. The system should be scanned by a certified technician and the wheel speed sensor replaced if found to be the cause. The warning lights will stay on and these systems will not function as designed until the fault is corrected. These lights do not come on to indicate a need for routine service. Rather they only come on when a component in the system is at fault.

Brake lights are not working. replaced brake light swtch still no brake lights. the third brake light the connection was melted at
ANSWER : The first thing to do is to repair third brake light and replace the brake light fuse and then see if the third brake lights work and the lower lights start working? If only the 3rd brake light starts working then you may need a further checks on the turn signal flasher or switch could be bad.

2012 equinox reduced power light engine light and traction light came on. Lost a lot of power got home and all light except engine
ANSWER : Your car has what is called a "safe mode" that will be engaged by the computer when it detects that something critical has gone wrong related to any of the major components in your engine chassis or power train. This may be related to a number of things, most of which should have been registered in the computer when the check engine light came on. I recommend having an expert from YourMechanic come to your location to inspect your check engine light and diagnose any codes registered by your vehicle’s computer.

Engine Light and AT light. Car goes into limp mode
ANSWER : Hello. Most of the time this is the result of a transmission failure. It is common for this transmission to have internal pressure problem which will cause these codes. It can also be a voltage problem so I always check that first. I check the voltage going to the transmission and if it is too low I repair that issue which is commonly the ignition switch. If the voltage is fine, then the transmission pressures need to be checked and it will more than likely need to be replaced. I would have a transmission specialist look into this.
