    Hey, Stephanie with americanmuscle.com, and this is my quick breakdown of the Whiteline transmission mount bushing insert available for the MT-82 6-speed transmission that is found on all 2011 to '14 Mustang GTs. Whiteline is a performance suspension company whose number one goal is to activate more grip in your ride, thanks to products like sway bars, Watts link kits, and other suspension components. They also specialize in designing and producing cutting edge bushing technology, thanks to synthetic elastomer material. We've used a few of Whiteline's products in the past. In fact, if you'd like to see more detailed product breakdowns along with project cars, well, then you guys should know what to do by now. Click the link below and subscribe to our YouTube channel, if you haven't done so already. Now, if you have a manual Coyote, then chances are you've already run into some of the common issues, such as high RPM lockout or lockout during aggressive cornering. This is due to the stock transmission mount and soft rubber bushing, allowing for excess transmission movement when the car is being pushed hard or when you're really trying to bang gears. This bushing insert from Whiteline eliminates the excessive play by filling small voids, strengthening the mounting location, and eliminating the high RPM issues altogether. The bushing insert itself is made from Whiteline's signature synthetic elastomer which usually does a great job of reducing noise, vibration, and harshness. I say usually, because in the case of this bushing insert, you may notice a little bit more noise inside the cabin. In fact, now is a great time to head back to the product page if you aren't there already to see what some of the customers have to say about running this bushing insert in their own ride. As far as installation goes, the site calls for two hours on this one, but a number of our customers have stated that it only takes an hour or less. This is an installation that takes place under the car, so make sure you have your jack and jack stands ready, or a lift if you're lucky enough to have access to one. Of course, detailed install instructions are available on the product page, and you can always feel free to reach out to a Mustang expert should you have any questions. If you're looking to improve the shifting situation in your MT-82 equipped GT then be sure to check out the Whiteline bushing insert available here at americanmuscle.com.

    Reduce Vibration. Whiteline's Positive Shift Kit also known as a Transmission Mount Bushing Insert fits neatly into the stock rubber mount to reduce driveline vibration and deflection when your banging through the gears.

    Quality Construction. This Whiteline Transmission Mount Insert is crafted from low compliance synthetic rubber which is much more durable than natural rubber to give you years of trouble free driving.

    Application. The Whiteline Positive Shift Kit (Transmission Mount Bushing Insert) is specifically designed for use on the 2011 to 2019 GT or BOSS Mustangs equipped with MT-82 manual 6 speed transmission and the 5.0L Coyote motor.

    Is there any part i can order to prevent the issue with the 2018 mustang gt MT82 shift forks from braking?

    • At this time we do not offer any products to reinforce the shift forks, however many performance trans shops are now offering a service to reinforce the shift forks, or replace them with stronger units of their own design.

    Since i already have the blowfish bracket, should i see a difference in shifting even if my shifter is bolted right on the transmission?

    • Yes, this bushing would reduce driveline vibration and deflection, which would also help to give a better shifting feel.

      More NVH equals less missed shifts

      Whiteline’s trans mount bushing is meant to stiffen the connection between your transmission and the body of the car to make your gears stay lined up at higher RPM. After installing, I immediately noticed a lot of vibration that was not previously there, despite drilling holes in the center part as everyone recommends to combat NVH. The shifter felt a lot more solid and centered, and it made it easier to get into gears even at normal driving speeds and RPMs. The crazy noise and vibration seemed to die down after about a week of it breaking in and I’m now able to shift into 3rd gear at close to 6500rpm which is about 500 higher than before. I still can’t shift into 5th gear without a fight at WOT but I’d say this product helps with some of the problems with the MT82.

      Didn’t like it

      Well all I can say is that I didn’t like it, had it in and back out in about 30 mins. While it did change the feel of the shifting, I could not stand the noise and vibration it caused inside the car. So for me,it was a waste of money. Adding this gives you the feel of having a solid of having a solid trans mount so you feel everything in the passenger cabin. As I said just not for me.

      Bushing Insert

      Shame on you Ford for a poor design on a transmission mount. I'm not quite sure what they were thinking … There is not support at all . The insert boot stiffened up the mount and took care of all the flex issues... very happy person here. Made a great improvement on shifting thru the gears at the strip.

      The Good, Bad and Ugly

      The Good - Bang for buck, this part does make a difference to how the car shifts, you will notice that you will actually be able to speed shift 3rd! The Bad - You will have to sacrifice drivability, because the part firms the driveline up to the point where you feel vibrations in the steering wheel and floorboard. There will also be a noticeable sound like a bearing that needs to be greased when the clutch is not engaged. The Ugly - Easy enough to install but awkward to reach - use some grease! I took the advise of others and cut the center portion out (used a utility knife) and still have benefits of better shifting without the driveline vibrations!

      No more missed shifts! Except for 5th..

      For as cheap, quick, and easy to install as this bushing insert is, you just cant beat it. I dont miss the 3rd shift anymore but for some reason 5th gear still locks me out under high rpm shifting. I did drill 2 smaller holes on the bottom of the bushing to take away some of the vibration that people complain about. Not sure if thats the cause of my 5th gear struggle but lets face it, tapped out in 4th is usually fast enough;) Really improves the lockout issue so Im pretty happy about it. Took about 15 min to install and if you have some wood clamps or C-clamps it makes the job worlds easier.

      Wow! My GT shifts again!

      Ever since the Boss 302 upgrade and required re-tune, the car hated shifting on load. Now it shifts smoothly again. Yes! It vibrates noticeably more off throttle. On the upside, free vibrating/massaging seats. Install is easy, takes longer to raise car on stands than to remove, install, replace brackets.

      Works...most of the time

      The vibration is something you get used to pretty quick. It works good with just me in the car then I’ve got two more people in the car and go to drag race (in Mexico) go to shift from first to second and full on lock out so needless to say you still will have problems

      Nice cheap mod

      Shifting is much smoother and more positive. I did have to modify the bushing by cutting the entire center portion off because it introduced too much vibration.

      Start with this

      I was having issues missing some shift hitting high rev lockouts and such, I was considering buying the short throw shifter but ultimately decided to start with this $30 mount over a $300 shifter. For $30 all of my problems have been resolved. Crazy easy install, literally 4 nuts, and slide the mount in

      2014 Mustang GT

      Extremely easy install with an electric impact. Just remember the bushing installs from the front towards the back by the instructions. I looked to see if there is any differences from the front and back of the transmission mount for this insert, and I did not see any, so I am not sure it really matters. Please pay attention to the transmission support when you reinstall it. There is a stamp on top side that has an arrow and it states front. Performance wise, I am not really sure it does much, but logistically it makes since.

      Huge Improvement

      The transmission up shifts and down shifts into gear much better now, especially 2nd gear. I drilled a 1 inch hole in the center as others suggested, to reduce NVH. Installing this did add some very slight vibration, but I think the slight vibration improved the feeling the car gives while driving. I feel more connected to it as a result.

      Missing gears??

      One of the best mods I've done to the car so far and a must-have if you replace the shifter and/or bracket. I've always had difficulty getting it into 5th gear at high RPM with my MGW, but this completely eliminated my "lockout" issue and made shifting into every gear a lot smoother.

      Every MT-82 needs this!!

      I had already installed a Barton shifter and bracket attempting to get rid of my third lockout, but the problem persisted. This product seems to have completely fixed it I have had it in for 2 weeks and haven’t missed a shift yet!! I am a mechanic so this was a very easy install with access to a lift.

      Big improvement

      This was easy to install and made shifts a lot more positive. It did take a little getting used to though . You can now feel the engine more in the body and shifter but now that I am accustomed to it I love it. Has the feel of a muscle car now. The shifter is now much more positive shifting. No more missed gears.
