My pedal makes a grinding noise and gears get stuck

ANSWER : It could be that you haven’t gotten all of the air out of the system. Bleeding the clutch carefully may solve the problem. Or it may be that the Clutch Master Cylinder is also worn out. Often I just recommend replacing both to keep from having the hassle of one wearing out shortly after the other. The third possibility is that there is a problem with the clutch itself. An experienced technician can tell you pretty quickly where this problem lies. If you contact Your Mechanic, you can have a technician come out to your home or office to check out your Acura and recommend a fix

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.

ANSWER : Hey there, thanks for writing in. I would have a professional mechanic check out the constant velocity joints on your vehicle. One or more of them may be worn enough to cause the noises you describe. S/he can diagnose and replace any failed CV joints.

ANSWER : Other consumers report the type of issue you have with various years and models of BMW but the reports are model specific. If you do a Google search ("difficulty getting reverse BMW "model, year") for your car, you can try the various strategies that I see published. I would suggest one, but I do not know which model you have. If none of those work out for you, that would point to there being a mechanical fault with the reverse synchronizer and related assembly in the transmission. That latter possibility being strongest of course if this difficulty in shifting is a "new" issue that you are experiencing. If you need help diagnosing the shifting issue, a certified professional from YourMechanic can come to your car’s location to inspect the vehicle and advise on the repair.

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.

ANSWER : Your vehicle uses a hydraulically operated clutch system. The first thing to do is check the fluid level in the master cylinder and check for leaks although leaks at the slave cylinder might not be apparent. Internal seal failures can cause the same problem that one might experience (i.e., no clutch operation) with visible leaks and a low fluid level. The noise may be due to a failed clutch release bearing. Due to the noise and the misoperation, if the slave cylinder turns out to be faulty, you will probably need a new clutch as well as hydraulic components. The cause of the fault that you are reporting can be pinpointed if you request a hydraulic clutch system diagnostic. If you request that diagnostic, the responding certified mechanic will get this diagnosed and let you know exactly what must be done. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

ANSWER : Hello. If the noise is still there when the engine is off and if you are not turning the wheel, then it is typically either a failing bearing in the rear differential or it can be a failure in the transfer case if it is four wheel drive.

The transfer case is a very common failure on this vehicle. If it is two wheel drive then I typically start by draining the oil from the rear differential and inspecting the fluid for metal.

Any metal in the fluid indicates a bearing failure. If that is also fine, then it may be an issue within the transmission. It may be a failure in one of the thrust bearings. If you need to get this looked at, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose your car’s grinding noise.

ANSWER : Hi there. The noise that you are hearing is something broken in your transmission. It sounds like the gears have damaged teeth on them and there are multiple clutches that are not applying. The transmission will need to be rebuilt or replaced. I recommend seeking out a professional, such as one from Your Mechanic, to help you diagnose your transmission grinding issue.
