My car won’t engage 1st gear 2006 Audi A4

My car shakes and will not move when in first gear, it only moves when in 2nd gear. My mechanic replaced the mountings and confirmed the clutch and gearbox are fine, but told me the flywheel should be replaced.

My car has 1665274 miles.
My car has a manual transmission.

Experienced mechanics share their insights in answering this question :
Hi there – I believe the problem is more likely with the 1st gear set in the transmission. If the clutch works in one gear, it will work in all gears. While a bad flywheel would cause the vibration and shaking you describe, it would also do so in all gears. There may, in fact be multiple problems at work here. Checking the flywheel, or 1st gear, will require removal of the transmission to access the flywheel, clutch, or to disassemble the transmission to check gear sets for proper operation. I would recommend a engine/clutch/transmission 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.

How to Identify and Fix Common car Problems ?

Hard, and sometimes impossible shifting into first and reverse is caused by the clutch disc not moving away from the spinning flywheel. This is commonly referred to as the “clutch is not releasing”. The number one cause is the hydraulic system that operates the clutch is leaking and has low fluid.
The gearbox is overheating and could be damaged. Stop the vehicle and let the gearbox cool down with the engine idling and the selector lever in position P. If the warning lamp and the message disappear, drive to a qualified workshop soon and have the fault rectified.
Loss of reverse gear (a common problem on Audi A4 CVT) Loss of gearshifts (stuck in one gear) Delay in engagement of forward and reverse gears.
When something`s wrong with the synchronizer, the first sign is usually a whirring or humming noise. This is the case if you`re hearing the sound at just one specific gear, rather than through the full range of gears. Similarly, problems with the synchronizer can cause a grinding sound.
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.
Depending on the issue (low fluid is an easy DIY job), most transmission problems can only be properly diagnosed and repaired by a reputable mechanic. Most transmission repairs require specific tools and replacement parts to get them back up to speed.
Short answer: no! The only thing you should do if you think you have a faulty transmission is go for a quick jaunt to your local mechanic. If you have a bad transmission it`s only a matter of time before your vehicle literally won`t be able to drive anywhere.

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.

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.

When shifting into 1st gear and attempting to take off, car shakes and then stalls. Car also won’t let me shift into reverse.
ANSWER : Hi there. Either the shifter rail is damaged inside the transmission keeping the gears from going into reverse and the first gear from connecting all the way, or the transmission first and reverse gears are damaged causing the transmission to have a hesitation on the forward 1st gear and no reverse. I recommend seeking out a professional, such as one from Your Mechanic, to help you diagnose your transmission shifting issue.

car hesitation in 1st and 2nd gears , its totally fine in higher gears . hesitation means light jerks , what’s the issue?
ANSWER : Hi there. You may be having an engine misfire since it is only when you are accelerating. The misfire may be due to worn spark plugs or the ignition system coil failing. The ignition system includes the spark plugs, wires, and coils which need to be checked for signs of failure. I recommend having the engine completely diagnosed and scanned for codes to see what is causing the misfire in the engine. You may only need a tuneup or may need more ignition components. I recommend having a technician, such as one from YourMechanic, inspect for trouble codes and replace any failing components.

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.

My car gear does not engage to drive position.
ANSWER : Hi there:

Sometimes this issue is caused by a faulty shift solenoid attached to the transmission; while in other instances, it can be caused by low transmission fluid or other damage inside the transmission. The best thing to do is have a professional mechanic complete a car is hard to shift inspection, so they can determine what is causing this problem and recommend the right repairs.
