There is something wrong with the clutch. Make sure that there is enough clutch fluid in it. For some reason the clutch isn't disengaging like it should, so you are grinding the gears in your transmission, making that awful noise. You want to get it looked at before you ruin your transmission by stripping the gears.
First of all I think I should say that clutches do not make grinding noises - but transmission gears do. However, a clutch that is not disengaging properly can make the gears grind when trying to shift from one gear to the next. Also a common source of noise is the clutch throwout bearing. This will make a "grinding" or "growling" noise any time the clutch pedal is depressed. In either of these cases, the only solution is to replace the clutch, throwout bearing, pressure plate and pilot bushing. These all usually come in a clutch kit. If you have an hydraulic clutch with an internal slave cylinder it is recommended to replace the slave cylinder as well and also the flywheel on on vehicles. I'm sorry I cannot be more specific because you did not mention what type of vehicle we are talking about here.
If the clutch has never been changed most likely it is that. The way you can check it is by removing the transmission and looking at the clutch disc. It could be transmission syncros but I am willing to bet you just need a new clutch.
Here is what is going on. When you push in the clutch pedal you remove the connection between the engine and the transmission. At this time all the parts in the transmission stop rotating.Since the only parts in the transmission that can rotate without moving the car are the input parts we can safely assume that the noise can only be from there.This can be a transmission input bearing. Worn Synchro mechanism (allows the transmission to shift without grinding the gears)Low fluid in the tranny. Or a bad clutch component. Top off or change the fluid. If it still makes the noise you need to take it to a tranny shop.
Have them flush the fluid out under warranty and put in new fluid, and have them bleed the clutch lines in case air is getting in there. Audi and VW claim lifetime transmission fluid but it's BS - I've changed relatively low mile fluid from these cars and it was horrendous. It's possible that the fluid itself is causing trouble, but it's more likely that it is a synchro problem. If it was a clutch issue, you should have problems with more than just reverse gear - a clutch simply engages and disengages the engine and transmission, regardless of which gear it is. The problem (if not fixed by fluid) is in the transmission, and being under warranty, don't accept another "suggestion" like they're giving you. Changing your clutch isn't gonna do it.
