RKX Billet Transmission Mount Insert Compatible With B8 B8.5 A4 S4 A5 S5 SQ5 Q5 8K0399151BD

First of all, let me start by saying that if you have an Audi that this will fit, it is a must have.This mount insert nicely fills the void around the transmission mount. It prevents the extra, sloppy transmission movement when shifting or accelerating or decelerating. I have a B8.5 S4 with the DSG, and I would notice some slop when on and off the gas at slower speeds (in traffic, for example). I associated it with slop within the transmission, but I was incorrect. The slop was coming from the mount. Shifts are now slightly crisper, but more than anything else, the jerkiness when on and off the gas is gone. My worry that there was a potential issue with my seriously expensive DSG transmission is gone. I should have gotten one of these the day I bought the car.As for the insert itself, it is of very high quality, and it fits perfectly. It is made from billet aluminum, so it is strong and light. It is an obvious clone of the same insert made by a bigger company. However, this unit costs less than half as much, and is the same design and quality. No need to overpay for a brand name for a piece of aluminum you'll never see after installation. Speaking of which....Installation is about a simple as anything under the car could ever be. It took me much longer to get the car in the air than it did to add this. Simply remove two bolts, slide this into the void around the mount, and replace the bolts. One caveat, you need the correct triple square bit (M10). If you don't have a set, get one. You can't do any real work on your Audi without it anyway. Do NOT use an allen wrench or Torx bit. Just don't. One more note; while the directions don't specifically call for it, blue Loctite is a good idea on the bolts. They don't get torqued very tight, so some blue Loctite ensures they stay in place.

Super easy to install. Surprisingly, you can feel the difference. Smooth shifting from slowing down and stepping on the peddle. If you can unscrew two 10m triple square. Then you can make this happen. Fits my 2011 Q5 2.0L no problem. Took less the 20 minutes. Not sure why the vehicle didn’t come from the manufacturer this way. I saved the piece I took of if anything should happen. Feels solid. I didn’t see the point of buy name brand as it’s material is the same. It’s better than the piece that gets replaced (original equipment). I think it’s value for the money for sure because it fits and do a better job than the OE.

Had this installed on my '13 Q5 3.0t last week to remove some of the slop and it made a noticeable difference! Smooth, crisp shifts with no change/increase in NVH (vibration). I could've installed it myself but it was cheaper to have my mechanic do it vs. buying the Audi tool, torque wrench, loc-tite, etc.

If you’re debating on this product and looking through the reviews, let me help with your decision. I got this product a few weeks ago. It came as advertised, it is a good looking product for half the cost of competitors. It’s a bracket so there’s really nothing that could be screwed up. I lifted the car up, took out the two bolts, applied blue thread locker, and tried to thread the bolts back in. They did not want to thread back in because once I took out the bolts, the mount moved just the slightest bit so when I tried to apply the new bracket, the holes were not lining up. So if you’re wondering, this job can still give you a surprise even as simple as it should be. I only jacked up the front on both sides so maybe having the car level at all 4 corners would’ve prevented this problem I had. Needless to say, it took me about 10 minutes of struggling to get these bolts to thread back in. I ended up using a flat head and gently wedging it to line the holes up to get them to go back in. Even that became a pain. I was installing in an Audi S4 so I expected nothing less than something becoming more complicated than it needed to be. Anyways, just reuse the original bolts, I don’t see a reason to waste your money on new ones. I torqued them to 25 Nm. As for driving, I will say there is definitely a difference you can feel. I always thought up shifting was quite a bit sloppy in this car especially at medium acceleration. This definitely made it quite a bit smoother through all the gears. I wouldn’t say it necessarily eliminated all slop but 80% improvement in my opinion. Downshifting was also an improvement. Coming to a stop would produce quite a bit of slop but with this bracket, it definitely improved it. I notice the downshifts improvement more than the upshifts. I didn’t necessarily get this bracket for track or racing purposes. I was just so tired of feeling the transmission slop and having mini heart attacks thinking I was having issues with my seriously expensive transmission. With respect to noise in the cabin, there was added noise for me. It is almost like a whirling noise that I can hear when I take my foot off the accelerator. This happens 35-45 mph. I can only hear it when I don’t have music on. Roll the windows down or turn the radio up, it wouldn’t be noticeable. To be more descriptive, if you had a passenger in the car with it silent, they probably wouldn’t even think anything of it. It’s a noise where only a daily driver would know about. I should mention, I am OCD about any rattle or noise that I hear so I’m always listening. So in the end, there was an improvement but it did add the slightest bit of noise at the speed interval I mentioned. Since this company advertised there was no added noise, it’s the reason they don’t get a full 5 star review. Again though, for the price and other improvements, I do think this product was worth it, so if you’re debating on it, just buy it and if you end up not liking it, it’s not the end of the world to put the stock bracket back.

Easy install and fits as expected on our 2012 Audi S5 4.2 with manual transmission. Shifting feels great so far. Solidly built, all aluminum and half the price of the market leading product too.

If you have a DSG transmission, buy it. Got rid of the hard start from stops and way better shifting! Much better price than the name brand (034) transmission inserts for the same exact product. Couldn't recommend a better product for the price.

Good alternative to the more expensive 034 Motorsports version. It fits well and seems to have helped with drivetrain slop. Make sure you tighten the two bolts evenly during installation to avoid problems.

Skeptical at first because of the price compared to an 034. Rest assured, this RKX does the trick! Eliminated that sloppy clunking shifting. Just throw some marine grease around it before inserting, and viola. Super happy with this product!

Fit perfect and installed in 15min
