Experienced mechanics share their insights in answering this question :
Hello. It sounds as though the synchronizers in the transmission, which are used to adjust transmission internal gear speed when upshifting or downshifting are possibly worn out or you are shifting a bit too fast. It is also possible that the clutch is not releasing fully when you press the clutch pedal. In some conditions, utilizing synthetic gear oil in the transmission can help the quality of gear shifting. If the clutch is not fully releasing an inspection of the clutch hydraulics is a good idea. I would recommend having an inspection of the hard shift completed 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 for repairs.

This kind of reaction is often a sign of low transmission fluid or a faulty transmission control solenoid. As you know, automatic transmissions use pressurized hydraulic fluid to change gears.

This noise is caused by the excess air in your transmission line. Commonly, drivers will notice this gurgling noise when their transmission slips while shifting gears. If you hear a gurgling noise, particularly while shifting gears, it may mean that your fluid levels are low enough to cause damage to your transmission.
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.
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.
Typically, there are a few common causes for hard shifting in vehicles. Oftentimes, hard shifting can occur when you fail to change transmission fluid at the recommended interval. In the event that your transmission fluid gets low or dirty, your vehicle`s ability to shift could become compromised.
Rumbling and growling

The growling of a bad transmission bearing, like the whine of a bad gear, will become increasingly more noisy while it wears, until the bearing seizes or falls apart, with catastrophic results.

Shaking, jerking or grinding

With a vehicle with a gearbox bearing failure symptoms, you may experience shaking, jerking or grinding while behind the wheel. Automatic gearbox issues often involve hesitation, slipping, or trembling during gear changes. Manuals are more likely to “grind” when suffering a gearbox fault.

The “check engine” notification on the dashboard isn`t reserved solely for engine issues. You will see this indicator light up when you are low on gearbox fluid as well. Friction due to the lack of gearbox oil may produce some burnt smells and even smoke.
When the temperature drops, transmission fluids with poor cold-flow properties can thicken and cause elongated and hard shifts until the fluid has warmed up enough to flow properly. Switching to a high-quality synthetic transmission fluid will help.
Disconnect the sensor from the housing on the transmission, as indicated in the repair manual for your car. Disconnect the sensor`s wire coupling. Using the multimeter`s voltmeter connect the probes to the ground and reference wires in the connector. If no voltage is received, the sensor is faulty.
For example, in some situations an oxygen sensor can cause poor shifting in your transmission – if the engine isn`t running correctly, the transmission control module may misinterpret when and where it`s supposed to be shifting, causing erratic behavior at the transmission.
There are 6 ways to improve automatic transmission performance and reliability. These are servicing the transmission, changing driving habits, driving with lower gears when loaded, maintaining engine performance, having proper alignment of tires, and having the correct tire size.
Automatic transmissions that shift hard, jerk or shake during a shift change may mean your transmission fluid needs changed or fluid level is low. In manual transmission vehicles, abnormal gear shifts could indicate damaged gear synchros, worn clutches or other, more severe issues.

I got sound when I shift to 3rd gear and it’s get hard to put shift to second gear when car is in 3rd gear.
ANSWER : Hello.

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.

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 car jerks when i put it on R/D and also there is a 2 seconds delay when i put it on reverse ( gear takes 2 seconds to engage )
ANSWER : The transmission has electronic controls as does the engine. It’s possible there is an electronic issue. A faulty transmission control module can give symptoms like you are experiencing. The brake light switch can also cause issues. On modern cars, the brake light switch also performs as a sensor for various systems like the ignition and anti-lock brake / stability control systems. Even if the check engine light is not on, there may be fault codes stored in the system. A certified technician can inspect the vehicle for shifting issues by scanning the system for faults. Fault codes will give the technician a direction to take in finding and repairing the exact cause.

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 filled my car up with gas, drove about a block to get a newspaper, put it in park and it died before i ever got out of the car .
ANSWER : With a car that cranks but won’t start, there are a few things that need to be checked. But before I explain them, there is a common thing that happens with Nissan’s. Every once in awhile they will flood the cylinders with fuel and wash the oil film off the cylinder walls and rings. This will reduce compression enough that the car will not start. Fortunately, there is an easy fix for this problem. It is what is known as clear flooding.

Hold the gas pedal all the way to the floor while cranking the motor. It won’t start immediately and when it does it will not run very well at first. Feather the throttle to keep it running until the motor clears out the excess fuel and the motor begins to run smoothly. If after cranking the motor with the gas pedal held to the floor for at least

Gears get stuck and hearing some noise in the exhaust. Some running noise that doesnt sound normal when parking. 1996 Mazda Miata
ANSWER : Hi there – either your clutch hydraulics (master/slave cylinder) are weak, or something wasn’t done right with your clutch repair. It shouldn’t fail so quickly. Either the clutch is dragging because the clutch hydraulics are weak, or the pilot bearing wasn’t replaced when the clutch was repaired, and that bearing is now seizing. This has the same effect as a dragging clutch – hard to get in gear when you’re stopped. I recommend a clutch inspection 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.

Second gear misshifts when I drive, all other gears are fine.
ANSWER : Hello.

A transmission coming out of gear is most often caused by worn transmission components. It may be possible that the synchronizer rings, which are meant to smoothly mesh the gears inside of the transmission, have worn out and are no longer able to stay in gear.

It may also be possible that the gears themselves have worn out, and can no longer hold the torque of the engine. This is usually preceded or accompanied by a grinding noise when attempting to shift into that gear. If this is the case, it may be possible that the transmission may need to be rebuilt.

As transmission rebuilds can be expensive, I would recommend having the vehicle diagnosed by a professional technician who specializes in transmission, to determine if a rebuild is required.
