Product Description

The Damond Motorsports Transmission Mount is a must have for any Mazdaspeed3 enthusiast looking to keep their powertrain solidly planted while adding less NVH than the competition.  Damond Mounts are ran on the quickest 1/4 mile record setting Mazdaspeed3s, as well as many enthusiast's daily driver Mazdaspeeds.

 

The Damond Motorsports TMM design:

  • The bushings are orientated properly to support the motor and absorb vibrations across the whole bushing.
  • This allows us to use stiff bushings without increasing NVH to unbearable levels. Orientating the bushing carrier in a transverse manner further reduces NVH, as less stress is put on bushing flanges.
  • Full length welded steel. 
  • CAD designed, and FEA, and street/track tested. You can't make enough power to break this thing.


The Damond Motorsports TMM specs:

  • Made in the U.S.A.
  • Machined aluminum bushing carrier, anodized gold or black
  • Lower mount base and top base are high strength steel welded, and powder coated black
  • All high grade fasteners, and lock nuts
  • OTS Energy poly bushings
  • Minimal added vibes, along with lots of tire spinning instead of wheel hop.

NEW! Bushing stiffness options! 

  • Street 70a or Race 88a bushing stiffness now available
  • Street bushings are for those looking to keep added NVH to a minimum
  • Race bushings are for those wanting the best performance and least engine movement
  • Bushing selection currently only applies to the side mounts. In full mount sets, the rear mount uses the "race" bushings

Note: This does not fit the regular Mazda3, this will only fit the Mazdaspeed3.

Necessary Upgrade

My OEM TMM was beyond done, and upon install of the Damond TMM, my whole engine had shifted several inches and was completely off. Made me feel better knowing that the OEM TMM done, and it will be better from here. Quick, simple install. Had to wake up the ol’ lady so she could hear and feel first start up. I will say she was as impressed as I was. She thought something was broken at first like when i installed the Damon’s RMM. Makes you feel your car more, better shifts and overall just smooth. Whole different car & feel. Cannot wait to get my PMM now.

Also I purchased TMM with race bushings, and I’m glad I did!
Thank you Damond Motorsports!

Transmission mount

Amazing mount. Makes a huge difference to driver feel. Night and day difference. Solid smooth shifts, crisp and direct. 10/10 would recommend. Mount is very stiff/solid and keeps the trans from moving under hard shifts and aggressive driving. Car feels way more connected to the road.

Must Have

Always had trouble with 1st-2nd and 2nd-3rd, missing gears and feeling slop. Once tuned on e85 the problem became worse and even experienced some grinding with the clutch fully engaged due to increased torque. Can't say I was surprised when I took out the oem mount and it crumbled into pieces. Oem mount is honestly a joke and I highly recommend Damond's mount. You feel so much more through the clutch and trans that you wouldn't experience otherwise, making you more connected to the car. There is added NVH, kinda has racecar vibes but it's to be expected. Got used to it in a week (might not be best if you're looking for a smooth quiet daily).

Great product

Easy to install and looks great. This mount is stiff as hell and it seems to be keeping the engine and tranny in place very well

TMM is superb!

Finally completed the trilogy and installed the Transmission Motor Mount, should have done it sooner because the OEM cracked and looked bad! Vast improvement overall. No torque steer, no wheel-hop what-so-ever, handles great, feels great, happy with all 3 mounts!

Another great product

I recently replaced the PMM with a Damond product with a tremendous difference made. Purchased this and the RMM to go with the PMM. With all pieces in place, wow! There is very little flex in everything now. Vibration and noise is actually better now than without these pieces, not sure if my mind is wanting it that way or if it really is, more miles and autocrossess to confirm this.
Another of many great products! Thanks Damond

Absolutely love this mount

This mount is amazing! I purchased the street bushings. I have this installed in a 2011 speed 3. There are next to zero vibrations inside the vehicle other than on decel. The tires feel well planted. There is a little clutch noise now inside the vehicle. Highly recommend this mount. My shifts feel more crisp too.

TMM = great feel and performance

I didn’t install myself this time so I can’t touch on install. I can feel the results, my car feels great. I daily my Gen 2 speed3 and the NVH is not worse and but the car feels way better than stock. I love my car feeling more solid because the engagement is significantly better. The street bushings are the way to go. I have all 3 mounts now. RMM, PMM, and TMM. All street bushings. They are my favorite mod thus far.

Better than Corksport

I had a Corksport TMM and I had a used Damond PMM that came with my Speed3, the USED Damond PMM had at least 40k miles (under my ownership) before it tore. The CS TMM I bought brand new failed in 25k miles of my ownership as the design of the CS TMM is perpendicular to the inertia of the vehicle movement which expanded the spacing between the bushing and the bracket that holds the mount. In addition, while it’s somewhat tedious to have the proper tools to assemble a motor mount in general, having the mount in pieces makes the installation so much easier and less geometrically challenging; the CS TMM removal was challenging as their design isn’t disassembly/removal friendly which means you gotta improvise just to install/disassemble the CS TMM. Bottom line from my PERSONAL experience with the TMM selection, DAMOND MS > CORKSPORT.

Solid, rock soild and zero vibration!

In just 9 months after new Fidanza flywheel the stock had completely blown apart and wasn't conected to anything but the bolt, pieces of rubber everywhere! Had clunks, knocks, slop and the car darted all over cause the tranny was moving so much!!! DON'T WAIT LIKE ME and just get it and see how much more power to the ground, zero wheel hop and so solid as I said!!! AWESOME BABY!!!!!!!!

TMM = solid performance

Installation was a bit of a hassle, mainly aligning the bolt that travels between the center bushing and top mount. Apart from that engine feels solid and very responsive, I have it paired with Damond’s PMM and CorkSports RMM. It does feel a little rough on the lower rpm range but once it gets going car feels smooth. Definitely recommend getting

AMAZING

My TMM was well overdue for changing. I really don't feel any increased vibrations eventhough I am FBO w/o balance shaft. My shifts are so much more crisp now.

TMM....mmmm

Should have changed this when I changed the PMM, but didn't have the scratch. Upon install the factory TM had let the motor shift so much and it was off by a few inches. After install motor doesn't move one bit. The NVH has lessened as it has broken in. Before you felt like a passenger in your car and weren't sure if it had some power or not. Let me tell you that this isn't the case anymore. The connectivity to the car actually makes you feel like a driver now. TMM makes you accountable to not only shift better, but makes sure you are in the right gear, and don't lug the engine and the turbo. I've tried to break the wheels loose and have still not been able to do so. Great upgrade.

Perfection

*kisses fingers like an Italian after boilng pasta to the perfect consistency*
Coming from a TRZ tranny mount after 9 years, this makes daily driving much more bearable. My bones don’t rattle while I’m driving around my 3 year old daughter, however, my shifts are smoother than they were beforehand.
Not only is the fit and finish beautiful, but the functionality is top notch. Bravo!

Excellent!

Strong but not too firm. A great upgrade from my old 88 duro TMM!

Trans secondary rear MM

I have all three now and the car(MS3) can be introduced to more power. It’s amazing how the car feels with the vibration and feeling of security and power when shifting! Thank you Damond Motorsports.

Great product!

I definitely love the new TMM. I have the PMM as well. The motor mounts definitely bring out a lot more out of your car and it also resolved the lazy shifts in between gears. Definitely worth it!

Edson Navarro
Easy.

Easiest installed transmission mount for the ms3, took me longer to removed the old aftermarket one, took out a lot of Interior nvh that it had before, great design guys.

Victor Kirby
Utterly fantastic

This mount belongs in a museum, not my car. These look and function absolutely amazingly. The clutch pedal feel is so much more responsive and the car feels just that much more planted. 10/10!!!

Anthony Belperio
Awesome

I installed this mount about 6 months ago now, and it's an awesome upgrade! Before I got this mount, I found that I was missing the 2nd-3rd gearshift more than I liked. Since having this mount, I've never missed a shift! Vibes didn't really change, however you get some transmission whine which sounds dope!
