Car only drives in first gear
The gears will not shift. The car will only drive in first and the key is stuck in the ignition.
Experienced mechanics share their insights in answering this question :
Sounds like you might be having an issue with your shifter mechanism. If the shifter is not fully in park, they key usually wont come out of the lock cylinder. Depending on the location of the shifter you many have debris stuck in there or possibly a broken shift lever cable. I advise seeking help from a mechanic, such as one from YourMechanic. The technician should be able to check out why your car is hard to shift and clean out any debris that may have fallen into the mechanism.

What you are describing may be a result of a faulty speed sensor, potentially low transmission fluid or a even a faulty transmission control solenoid. As your vehicle travels down the road, the computer analyzes data being sent by vehicle speed sensors and engine speed sensors.
A transmission may stay in first gear due to low transmission fluid, a faulty shift solenoid, a worn clutch (for manual transmissions), a malfunctioning transmission control module, or broken transmission bands. These issues can prevent proper gear shifting and result in the vehicle being stuck in first gear.
This may be a sign of low transmission fluid or a faulty transmission control solenoid. As you know, automatic transmissions use pressurized hydraulic fluid to change gears.
The pawl is what locks the transmission and keeps it from transferring mechanical power to the wheels of your vehicle. Shifting gears while still in motion can damage this locking mechanism. And if this part fails, your vehicle could easily roll away.
Automatic transmission problems can be caused by a lack of transmission fluid. If you are experiencing slipping, the first thing you should do is check your transmission fluid levels. If they are low, you should top it up and check for leaks. Slipping can also be caused by burned or worn out fluid.
This is often times a sign of low transmission fluid or a faulty transmission control solenoid. As you know, automatic transmissions use pressurized hydraulic fluid to change gears.
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.
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.
That could be a slipping clutch. If the engine just will not rev in 2nd gear, it could be many things, including bearings, vacuum advance issues, electrical / spark issues. The list goes on. Get the vehicle to a qualified mechanic and have the source of your problem identified.
The throttle cables need checking. As we have mentioned earlier that changing the transmission fluid alone solves many transmission-related issues. But, if you change this transmission fluid and your auto transmission still won`t shift into the third gear, the throttle cables are the next suspect.
Is it safe to shift the gear lever to “N” from “D” while the car is moving? If your car has an automatic transmission, you should not shift the gear selector from D to N (Neutral) while the car is moving. The automatic transmission has a built-in hydraulic pump that is driven when transmission is engaged.
It is widely believed that switching the car to the neutral mode while driving will save fuel. However, it is dangerous to do so. Switching to neutral will reduce the control you have over the car. This can prove to be life-threatening in a risky situation.
Low gear, also known as first gear, is a mode on both manual transmissions and automatic vehicles, which restricts the amount of fuel injected into the engine. This mode helps to boost torque while decreasing engine speeds.
Transmission Fluid Low or Poor Condition – Vehicles low on transmission fluid or that are operating with worn out or contaminated fluid are likely to experience hard shift conditions. Lack of adequate lubrication within the transmission can cause several problems, including hard shifting.

Car only drives in first and reverse
ANSWER : What you are describing may be a result of a faulty speed sensor, potentially low transmission fluid or a even a faulty transmission control solenoid. As your vehicle travels down the road, the computer analyzes data being sent by vehicle speed sensors and engine speed sensors. Based on this information, the Engine Control Unit (ECU), or the Transmission Control Unit (TCM), executes the appropriate upshifts and downshifts by sending a signal to one of several shift solenoids. These transmission solenoids have spring-loaded plungers inside them, which are wrapped with wire. When this coil of wire receives an electrical charge from the TCM / ECU, it causes these plungers to open, allowing transmission fluid to flow into the valve body and pressurize the desired clutches and bands. When this happens, the transmission changes gears and you continue down the road. The computer controls the transmission solenoid in several ways. If the vehicle is equipped with a dedicated Transmission Control Unit, it can open or close the hydraulic circuit using a direct 12v signal. In some cases, the Engine Control Unit (ECU) can control the solenoid’s plunger by turning the ground circuit on and off. When this is not working properly, this can cause a jerking reaction, a delay in shifting or in some cases may cause the transmission to hesitate in shifting gears. I would recommend having a professional from YourMechanic come to your location to diagnose and inspect your transmission.

My manual car won’t go into gear, it turns on and the clutch goes down perfectly fine. It happened after my gears grinded, the car
ANSWER : If the clutch mechanism is releasing properly, and the shift linkage is not malfunctioning, your transmission will have to be removed from the vehicle and inspected. Once a transmission has been removed from a vehicle, if the problem is a broken or worn part or parts, and the transmission has 100,000 miles or more, the most cost effective approach is to just simply rebuild the whole transmission. There are transmission rebuild kits that are sold just for this purpose. Rebuilding a transmission is no big deal and is indeed easier in many respects than rebuilding an engine. You can rebuild your transmission right in your own garage. You can NOT rebuild an engine in your own garage due to the highly specialized, and extremely costly, machine shop equipment required. Occasionally, mobile mechanics will take on a transmission rebuild job especially as once the mechanic removes the transmission from the vehicle, it is just simply a modular unit that can be easily transported to a mechanic’s shop and rebuilt right there and then returned to your vehicle. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

The car doesn’t shift into first gear while it works fine in reverse
ANSWER : The problem could be that the internal transmission pump is weak, or the transmission clutch seals are leaking. It sounds like the transmission will need an overhaul.
I recommend having a transmission mechanic test the pressures and diagnose the problems to verify whether you need an overhaul with a new torque convertor.

I was driving had my car on gear and lost acceleration. I pushed the clutch in and put on gear but only grind but won’t move?
ANSWER : If the clutch lever, on the transmission, is functioning something has mechanically failed in the clutch and/or the transmission. If the clutch failed, and you heard gears grinding, as you tried to shift the transmission, some damage may have been done to the transmission. Even if just the clutch has failed, the engine and transmission will have to be separated to find the cause of the failure and worn out or broken parts will likely have to be replaced . To request an inspection, the recommended service is clutch system diagnostic. If you request that diagnostic, the responding certified mechanic will evaluate what you have and let you know of your repair options and costs. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Thumping when going into first gear. If I bypass first and start off in second and then change up to drive it’s ok.
ANSWER : Hello, the harsh 1st gear engagement you describe is likely the electronic pressure control solenoid failing. Although you have a work-around by starting in 2nd gear, the problems with internal control pressures will start damaging other parts. I would have a reputable transmission shop perform a diagnosis on the transmission; which will include checking the transmission line pressure to confirm this diagnosis, with a fluid/filter change. If you’d like a second opinion on this, have one of our mobile technicians come out to your location and diagnose the issue with your gears firsthand.

Car won’t go into gear. 2002 Audi A4 Quattro
ANSWER : Hi there – Your symptoms describe the behavior to expect when your clutch hydraulics go out (clutch master and clutch slave cylinders). Check your clutch fluid level – it may be low. If the fluid level is low, this usually means your clutch slave cylinder has worn out, not unusual with your mileage, and should be replaced. I recommend a malfunctioning clutch inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
