    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 2018 GT or BOSS Mustangs equipped with MT-82 manual 6 speed transmission and the 5.0L Coyote motor.

    Does this work in conjuction with the Barton shift-throw shifter and shift bracket or is this a replacement for the bracket?

    Talonderiel

    • Yes, it will work fine. This is for the transmission mount. It will keep the trans in proper alignment, which will give your new shifter bracket something much more solid to work from.

      White line solution

      It was super easy to install the white line trans.bushing in my 2018 PP.1 GT. At first the shifter was a little notchy after install but in a couple of days it was back to the same performance shifter I loved . I don't push my GT. very hard but some times I really like to burn it up 1st through 4th and with the white line bushing it has become much easier to shift in the higher rpm range . If I had to buy white line all back over again I would not give it a second thought .It is made for performance like my GT.

      Nice feel, nvh not bad

      First thing I did was drill a 3/4 hole in it because I didn’t want alot of NVH. Install was a breeze once you find torque specs. Shift feeling is a little firmer. The whole car has a slight vibration from 2-3k rpm. But I’m young and don’t mind it. Over all not much difference, but I can feel it. Worth the $30 PS this thing smells really weird once you open the bag...

      Best mod for the stock shifter ever.

      This mod is platinum-status. I have been driving my new mustang gt for a year now, and I thought i forgot how to drive standard. It was hard to put the car in reverse, first-gear, and third. It was like some days were better than others. Took the car to ford and they said nothing was wrong and the mechanic told me just work on your shifting. I have driven standard since i was 17, and I'm 36 now. I knew something was wrong. I found this little rubber piece of heaven on American Muscle describing the same issues i was having. I ordered it, put my car on Jack stands, grabbed the whiteline bushing, greased it up, put in on, and immediately felt the difference in daily driving and hard passes. A note on installing... Don't give up!!! It does fit the area, just keep inching it in until it seats flush.

      What you would expect

      While I was installing the Barton Hybrid 3 and Magnaflow Competition Exhaust (both are must haves), slipped this into place. Didn't receive grease, but it honestly slide in with a little bit of hand force. Barton is body mounted, shifts are super quick and engaging. Inset fills the factory void. Somebody else said it best "its 40 bucks of noticeable difference". Would I buy/install again - you betcha.

      Inexpensive yet effective

      Easy install, less than an hour. Just make sure you have the correct torques for the transmission crossmember and mount. Bushing reduces transmission/body flex and and shifts feel more accurate and smooth with this bushing install. If you plan on doing any work underneath your Mustang, you'd be smart to throw this in there while your under there. This part along with a solid mount shifter will significatly increase shifting effeciency and prolong the life of your syncrhos/ transmission.

      Easy improvement

      Got this installed when i got the boss side pipes installed on my 11 GT. It took the mechanic all of 2 whole minutes to detach the trans brace, slide it in, and rebolt the trans brace onto the car. Can notice crisper shifts when going around corners especially the 2-3 shift.

      Fills the void

      Haven’t driven yet after installing. After seeing how much empty space is in the rubber transmission mount bushing; I can’t see how this would do anything but firm up the transmission movement under spirited driving conditions. Should be a good upgrade for the money.

      Cheapest upgrade, best result!!!

      After adding the Barton 2 post bracket (which helped tremendously), changing the transmission fluid the BG syncro shift II (also very helpful), I was pleasantly surprised to find that this bushing was the final piece of the puzzle to turn my mt82 into the smooth/reliable/consistent transmission I’d hoped to get. There is a slight increase in NVH, but it is a small price to pay for the dramatic improvement in shifting. No more missed shifts between 1st and 2nd (Barton fixed the 2nd to 3rd issue). Camaros beware - 500 rwhp with perfect shifts!!!

      The product fit. It was an easy install, maybe an hour. Its clearly well made (although I drilled a hole in the center to alive NVH. But now its on and I kind of notice a difference. You get what you pay for. Its a 40 dollar difference.

      Does just what others say...

      Purchased this knowing I might not like the added vibration described by others. I already have a fairly stiffened up GTPP, and also installed the BMR diff bushing inserts, and Barton shifter (mounted to transmission) at the same time, so a notable amount of added NVH was expected. I also first drilled an oval 1.5" hole in the bottom part. This part seems to have made a worthwhile improvement, but since I already have other upgrades to address the sloppy transmission, I might try cutting the bottom section off completely to see if that reduces a little of the vibration through the shifter. I doubt I would ever take it out completely, after seeing how mushy the oem mount is up close... NVH is a very relative topic, and in my opinion if you're already considering a part like this, and are mechanical enough to install it yourself, you'll probably love it, and should expect it to add some vibration. If you are only looking for tighter shifting with NO added vibration, go with something like the Blowfish bracket, or a just whole new shifter. For the price, and ease of install, this is a great item.

      What a difference this made!

      You don't have to bang gears very hard to find out that Ford had issues with the shifter/trans combination they use. Too much flex! Shifts bind between gears! This is the best $30 I'll ever spend on this Mustang. They say that install time is 2 hours. I'm spoiled, I have a lift and a stationary tripod that I used to install this. Took 20 minutes. Once I got it started in the gaps in the transmission mount, I used a C-clamp to get it almost all the way in. After that I used a rubber mallet and a long 3/8" extension and tapped it in. Done! It really is that easy. I can do full throttle shifts with no binding. Great product!
