Hi there. Check the shifter lock solenoid in the shifter housing. The lock solenoid may have an issue as the ignition key is on. I recommend replacing the shifter lock solenoid. Also, I recommend seeking out a professional, such as one from Your Mechanic, to help you diagnose your lock solenoid in your shifter if your vehicle still continues to not going in into park after replacing the shifter lock solenoid.

Why the Transmission Won`t Shift Gears. One reason why an automatic transmission isn`t shifting into gear has to do with the fluid. If it`s not at the right level or the incorrect type has been used, then it`ll affect the gears. Another big reason has to do with the ECM possibly going bad.
Delay in shifting gears
This can be caused by things such as low transmission fluid, a damaged shifting cable, or a worn clutch. If you notice a delay in shifting gears, it is important to bring your car in for repairs quickly, as it can be a dangerous symptom to drive with.
In most cases, this issue is caused by a damaged shift solenoid or perhaps an obstruction of debris inside the transmission hydraulic lines. It could also be caused by damaged inside the transmission…
Check to see if the brakes are applied and see if the master cylinder is full of brake fluid. If you need further assistance with your vehicle not moving when putting the transmission in drive or reverse, then seek out a professional, such as one from Your Mechanic, to help you.
Turn off your vehicle`s ignition and wait patiently for 5 to 10 seconds. Start the engine and allow it to idle for several seconds. Switch off the ignition and wait patiently for another 30 to 40 seconds. Repeat these steps 2 to 3 times in order to reset your vehicle`s transmission control module.
The brake light switch is the main culprit for your gearshift being stuck in the mode. It`s a small sensor located on the brake pedal that prevents the car from starting if the brake pedal isn`t depressed.
Grinding, Jerking, or Shaking Shaking and jerking are good indicators of transmission trouble. Gear grinding is a common symptom in manual transmission vehicles. Automatic transmission failure often begins with some hesitation during gears shifting. Some might describe this a “slipping,” as well.
How Long Does it Take? If you take your vehicle to a repair shop that has the right tools and the information from the manufacturer, the process takes about 30 minutes to complete. Reprogramming a transmission shouldn`t take very long.
Transmission Range Sensor (TR)/ Transmission Position Sensor The PCM uses this information to control which gears of the transmission to enable or disable. When the TR sensor fails it can cause wrong gear starts, no upshifts, or what feels like a falling-out-of-gear condition.
According to the experts at our Mercedes-Benz service center, a typical automatic transmission should last around 150,000 to 200,000 miles–that comes out to roughly seven years of use.
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.
Maintain Proper Transmission Fluid Levels
The #1 cause of transmission failure is low fluid, which causes overheating. In automatic transmissions, it causes delayed engagement, harsh shifts, and slippage.
For your safety, the automatic transmission has a shift lock system which prevents shifting the transmission from P (Park) into R (Reverse) unless the brake pedal is depressed. To shift the transmission from P (Park) into R (Reverse): Depress and hold the brake pedal.
When it comes to Powershift faults, the sensors inside the transmission are often to blame. If the magnets that relay information to the sensors become dirty, the readings they pick up can confuse the control module. This can often be fixed by dismantling and cleaning the sensors and changing the oil.
Disconnecting a battery will not typically reset the transmission. However, it may reset the vehicle`s computer systems, which could affect how the transmission operates.
Find the reset button on the left side of your instrument cluster. Press the reset button and hold it until your display shows “To reset: Press reset button for 3 seconds.” Push the reset button again and hold it in until the display shows the system has been reset.
Typically, two sensors communicate the transmission data to the vehicle`s powertrain control module. The first sensor, referred to as the input sensor, monitors the speed of the transmission`s input shaft. The second sensor is the output sensor, which monitors the output shaft speed.
Trouble Shifting Gears
A clogged catalytic converter makes the engine work harder, which in turn makes it difficult to shift the transmission. In regards to air, a bad O2 sensor or dirty mass air flow sensor will also cause the gears to stick.
This requires specialized experience and education, which is why you`ll want a mechanic to address the issues. Vehicle transmissions are one of the more complicated components of a vehicle and, consequently more difficult to repair or replace.
The TCM fuse is in the main fuse block and is probably 10 amps. If the fuse is blown, that is confirmation but the faulty fuse means there is a short circuit in the TCM and/or wiring that would have to be traced and repaired.
Most repairs are fairly quick. Flushing the fluid, sealing, and recalibration can be done within a day. Replacing the shift solenoids takes a day or two. A full rebuild, however, is very time and labor-intensive and will typically take three to four days.
Drive. Some cars have D+ and D- instead of D1 and D2 to indicate lower and higher gear. D in an automatic gear shift lever means Drive. It engages the forward gears in the transmission. The transmission will automatically shift between the gears as the vehicle accelerates and decelerates.
The governor is inside the transmission housing, attached to the output shaft, which means it turns along with the drive train. So as the wheels turn, so does the governor, and its input signals the shift valve to shift or delay a shift at a certain RPM.
