how to install a transmission mount insert

I already have the 70d RMM in my 2013 speed, and just decided on throwing in the TMM insert based on the positive feedback i was hearing. I am happy to say it does not disapoint. Install was very straightforward, about 30 minutes or so (make sure you have a nice breaker bar for the one bolt). Torque steer has been reduced slightly, as well as wheel hop. During hard driving, i now notice i can easily shift between 2-3 very smoothly, whereas I used to have many issues with 3rd locking me out for a second.

For the money, I would highly recommend this simple modification, especially when you see what the current TMM bushing looks like!

Installed today. And like another post says, "goes great with the rear motor mount". Install....kinda sucked. But worth it. Actually had that feeling of accomplishment when done. Does what it says. With the other mount and this...a lot of even traction....May make you want more power..haha. Cool deal for not a lot of cash. Thanks Corksport!

This product goes great with the Corksport rear motor mount, and for this price you would have to be crazy not to get it. Huge difference and this helps put your car's power to the ground.

Installed the insert. Butt dyno says there is an improvement, the center bolt was a PITA but to make it easier we supported the engine and raised it untill the oem tmm mount lifted off the bolts a good bit than the bolt came out easy with a breaker bar

What are the differences between the Mazda 3 2.5 TMM and the MS3 TMM?

CorkSport Reply:The shape.

For those having problems,

Go to Harbor Freight and get a two foot breaker bar for $10. Bolts come loose easy without any lube. Best tool in my toolbox.

Ok fyi if you're interested in this part save your self the time and go buy some liquid wrench or a type of bolt loosening oil that you can let sit for at least an hour! I had this part sitting idle for nearly a month, 3 wrenches, 1 extension, and striped 2 cheap socket 17mm. Some people probably won't go through what I went through but it's worth it with all I iv gotten done to my mounts and shifter and bushings, power, ect... this pulled it together, I no longer miss gear, take off is stable, shifting is accurate in all gear and speed ranges, torque steer considerably decreased. Overall (with current supporting mods) this insert has pulled my whole speed3s power to the ground like a champ

Still cant get that bolt out ! Driving me mad

Looks great - does it fit a 2010 3 GT (2.5L), or are these for speed 3s only?

CorkSport Reply:These are specifically for the 2010-2013 Mazdaspeed 3.
