Disclaimer: NVH (noise, vibration and harshness) This product will cause an increase in NVH, including a transmission sound/whine, may be more apparent.

Since I changed my passenger Motor Mount I decided to change the other two left. Excellent quality and easy to install. With all three mounts changed on my car you feel the rumble but that really doesn't annoy me.

Deff worth the money. I have the Trilogy package and despite what anyone has to say the vibration really isnt that bad. The BSD makes the engine really rowdy with these mounts and so does the ACT flywheel. but other than that its really not as bad. launching with these has no torque steer at all. and the motor has no movement at all making shifting very smooth

As usual another great product . It feels great and a noticeable difference in grip. Quality part and pretty easy to instal. The down side: not for people who do not like noise. It is hard to tell since this completes all 3 mounts from Corksport for my car. (Wish I did all 3 at the same time). But you hear everything under the hood. If you don't mind noise and like to put power down this is for you. Thanks. PS. Rooney does not mind the noise.

Definition of what you would want in a business model for customer service and the way the Corksport team is set up. Quick emails with really help full staff quick deliveries even to Canada although watch out if you order a large package COD can be expensive.

Product is amazing! knowing that i have this part in my car rather than the stock piece of junk is a great relief for reliability, and im planning to put a lot of power into it so it should ease wear on my transmission since ill be using it as a daily.

As far as noise i bought my MS3 with a RMM so i already felt like there was a loud humming which i honestly didnt mind. This Transmission mount makes a few distinct noises and i honestly love every one of them. the whirring while gearing down, the feeling of the part actually doing its job, and the feel of the cars power transmitted to the pave gives the car a feeling ive never drove before! didnt think handling would be improved but it feels more sturdy.

I cant even believe mazda puts those junk stock donuts in there in the first place they should come with this part.. maybe just my opinion. great job Corksport!

Another awesome product from Corksport. I went from the CS TMM insert to the full TMM and yes, there is much more transaxle noise, but it's a satisfying noice for me because the CS PMM was transmitting more NVH than the RMM or TMM insert, the full TMM kind of evens this out. The insert is great, it works wonderfully, and adds almost no NVH, but the full TMM compliments the full PMM/RMM combo better and just locks down the whole motor/trans assembly down better. I have also noticed 3rd is a little better to quick shift into, but I did adjust my CS SSP to full 40% from aprox 30% when I installed the TMM.

The insert is much easier to install but the full TMM is still fairly easy, removing the BBox is the worst part, especially if you have the CS BBox. Having some ratcheting 17mm (for the 2 hidden mount to trans nut/bolt) and a ratcheting 19mm (for the TMM bushing center bolt) wrench will save you a lot of time, and are worth buying for this job.

It's very difficult to properly torque the 2 hidden 17mm bolt/nuts, use a full length 17mm and tighten it as much as you can by hand, then recheck in 500miles or less if you hear/feel any movement. Also, tighten all your nuts and bolts a bit at a time, like you would a valve cover or oil pan, this will pull the parts together more evenly.

I just went on a 1500km drive with it and I love it, it definitely helps with shifting, launching, and handling. With all 3 CS mounts i have reduced torque steer by at LEAST 75-80% or more.

Awesome mount!! It is a pretty easy install process. There is a little bit more vibrations at certain RPM's but it makes the driving experience a lot better. Gives the transmission a solid feel and transfers the power to the pavement. ADD TO CART!

Being the first time I have ever swapped out a mount of any kind, the included instructions were perfect and explained step by step in an easy way of what to do.

The mount itself is awesome. The stock one is basically a giant piece of rubber with a floating bolt in the middle, the corksport one is so much stronger it is ridiculous how flimsy the stock one seems. Be warned though, it greatly increases vibrations and noise as it is a lot stiffer, but I have absolutely no wheel hop now. My speed just stays planted on hard launches. I would recommend this is to someone looking to upgrade for a more racey feel, because you can actually hear and feel the transmission now.

I decided to order this mount after snapping off the main trans bolt trying to install the transmission mount insert.

Install was straight forward and went as expected.

Pros:

- Seams to have a very strong hold of the motor and performs as expected

Cons:

- VERY large amount of vibration and noise

- The transmission noise and vibration is louder than my cbe from you guys

At this point I feel like I would have been happier with just the insert.

Hopefully it will break in and tone itself down a bit. Otherwise I may keep the insert and go back to OEM with insert :/

This whole transmission mount almost works TOO well

Does this work in conjunction with the insert?

If you were to replace both the Mazda 3 OEM Motor mount and #4 transmission bracket (Mazda 3 2.0 2013) would the CorkSport mount bolt up?

Does this mount fit 2006 Mazda S 3 MT? the MS 3 OE mount looks identical to mine. Is there a difference how this mount is installed in the car compared to stock?
