My car has 134000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
This sounds like a faulty speed sensor problem. Most cars have two speed sensors (one monitors input shaft and one monitors output shaft) which tell the computer what the gear ratio is of the transmission while in use. If either of these are not working properly, they will cause the computer to shut the car off for safety reasons. I would suggest having an expert from YourMechanic come to your home to diagnose your stalling issuee and help you repair it.

How to Identify and Fix Common car Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced mechanics :

Dead car battery. Dirty air filter. Faulty charging system (alternator, fuel pump, EGR valve) Ignition problems.
Common culprits include a faulty fuel pump or fuel pump relay. A clogged fuel filter or bad fuel pressure regulator is also common on return-type fuel systems. Another often overlooked problem is the vehicle simply being out of fuel. Sometimes the fuel gauge breaks or is inaccurate.
Fuses – If the car dies while idling but restarts, there`s a possibility that there might be an issue with the fuses of the car. It`s conceivable that one of the fuses has blown. Take each fuse from the box and hold it up to the light.
This causes the engine to lose power, RPMs will often increase, and the engine might smell bad. When the transmission has actually gone out, basically your vehicle will not move. This is because the gears can no longer get power from the engine. As a result, the engine will idle, stall, or surge when shifting gears.
Malfunctioning spark plugs can make an engine stop for a while and resume its normal functioning. It can happen when you are driving. The engine can also sound rough when idle. The misfires affect the proper functioning of your car`s engine due to failing spark plugs that have no power to ignite the fuel-air mixture.
The most common culprits include clogged fuel injectors, clogged transmission fluid lines, bad fuel pump, bad fuel filter, failing idle control valve, failing sensors, and poor earthling connections.

Stays idling when I put it in gear, and the car doesn’t move. When forced into any gear without the clutch, the car does not shut off.
ANSWER : Hi there. The clutch may be worn and slipping causing the engine to stay running as the shifter is put into a gear selection. If the clutch was working, when put into gear and let off the clutch pedal, the vehicle will either move or stall out the engine. Check the slave cylinder and see if the return spring has broken off causing the clutch fork to stay engaged. Also the clutch adjuster cable could be out of adjustment or damaged. If the pedal and hydraulic assembly has no issues, then I recommend seeking out a professional, such as one from Your Mechanic, to help you diagnose your clutch.

I put the wrong key in my car and a few weeks later my car just shut down and it will not start I believe it’s the computer but…
ANSWER : Hi there. What had happened is the wrong key set the security to the vehicle. This is to prevent the vehicle from starting with the wrong keys. Try removing the battery cables (+) and (-) for 13 minutes. During that time, put the original key in the ignition and turn it on. Activate everything in the car even though there is no power. Then remove the key and hook up the battery cables. The computer should have reset and reset the security. If the security is still being tripped, then I recommend seeking out a professional, such as one from Your Mechanic, to help you

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.

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.

Suddenly cannot shift car into gear.
ANSWER : Hi there:

There could be multiple problems on your Saturn that are causing this problem you’re experiencing. If your clutch is worn it won’t allow you to put your car in gear. When you step on the clutch, the transmission disengages from the engine. This slows the insides of the transmission just enough to allow you to shift gears. When the clutch is worn, the slave cylinder doesn’t have enough travel to disengage the clutch from the engine, so it wont allow you to put it in gear. It’s also possible that you have broken a shift fork in the transmission. The shift forks are what actually move the slides inside the gear box to engage the gears when you move the shifter. The best way to determine exactly why you’re car won’t shift into gear is have a professional mobile mechanic complete a car is hard to shift inspection.

Car won’t move. I can start the car but when I put the shifter in 1st, 2nd, 3rd, ect. The car will not move.
ANSWER : The transaxle is not engaging internally to the axle shafts inside the transaxle or you have one or both axle shafts disengaged from the transaxle. The fact that the speedometer moves when gear is engaged and clutch is released shows the speed sensor in the transaxle is getting turned.

You will need to have the vehicle raised and the axles inspected for broke or stripped shafts. If the axles do not have anything visually wrong with them then hold one wheel and try to turn the other wheel while transaxle is in gear, with engine off, to see if the wheels are locked together. When you spin one wheel the other wheel should turn in the opposite direction. If it does not then the problem is in the transaxle differential gears and the transaxle would need to be removed and disassembled to find the broken internal components.

If you need some assistance with this, consider YourMechanic, as one of our mobile technicians can come to your home or office to diagnose your acceleration issue and help make the necessary repairs to get you going again.

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.
