Transmission won’t engage or stay in gear
If when you put your vehicle into gear and it won’t move, this may be a problem with low transmission fluid due to a leak, the shifter, shifter cable, or it could even be a problem in the valve body of your automatic transmission.
Over time, dirt, debris and other tiny particles can accumulate in the transmission fluid, affecting its fluid properties. This can cause the vehicle to die when you shift into drive or reverse, allow a loss of power, transmission slip, rough shifts or even prevent the vehicle from shifting into gear at all.
What does it mean when your car starts but wont go into gear?
The first culprit to suspect when your vehicle refuses to go into gear is low transmission fluid. Perhaps your fluid is leaking or low, and that may cause your car problems having a smooth gear transmission.

How do you fix a transmission not shifting?
The first thing to do is check the transmission fluid. Hydraulic transmission fluid is the lifeblood of an automatic transmission. If the level is low or if the fluid is too old, there’s a good chance that it’s responsible for issues when shifting gears.

Either the brake light fuse is blown or the brake light switch is faulty. These are the most common reasons for a shifter being stuck in Park.
What does it mean when your gear doesn’t move?
The number one cause is the clutch components have worn out and no longer have enough friction material to overcome the weight of the vehicle. A second possibility is the transmission can be stuck in two gears at the same time and it won’t move. The shift mechanism can malfunction and keep you from selecting a gear.
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.
What sensors can affect transmission shifting?
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.
What happens when the shift solenoid goes out?
Ignoring a warning light or code being thrown by a faulty transmission shift solenoid can lead to serious problems, such as running your vehicle in the wrong gear for your speed and conditions. This can then lead to your transmission overheating and breaking down.
Can low transmission fluid cause no shifting?

You can add more by inserting a funnel into the tube the dipstick was withdrawn from and pouring a small amount of automatic transmission fluid into the pipe. Check the level each time you add a little until the level is right between the two lines.
What happens if you drive with low transmission fluid?
Driving your car through a low transmission fluid level is dangerous to you and the vehicle. Failure to top up the fluid is a hazard that might cause extreme damage to the transmission, the engine, and essential components that keep the car running.
Do you leave truck running when adding transmission fluid?
Your car’s engine should be running when you add fluid to the transmission, but you should have the transmission in park and the handbrake activated for safety. Check the owner’s manual for instructions on selecting the correct transmission fluid for your vehicle.
What happens if you put too much transmission fluid in your car?
Transmission fluid will become foamy if there is too much fluid. Excessive fluid prohibits proper lubrication and cooling and slows the rotating crankshaft, similar to the effect of running through water.
Why does car go into limp mode?
When one of the signals is abnormal, the car will revert to limp mode to prevent further damage. Problems which cause signals like this are usually faulty engine sensors/components/wiring, transmission issues, dysfunctional brakes and clutch, or even low fluid levels.
How many miles can you go over transmission fluid?
If you drive manual, most manufacturers will recommend changing your transmission fluid every 30,000 to 60,000 miles. If you have automatic, you can typically boost that range up to 60,000 to 100,000 miles. There’s no harm in changing your fluid early.
