    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 2020 Mustangs equipped with a manual transmission.

        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.

        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.

            Easy Install

            I was able to rectify my fifth gear lockout issue with this and there is only a small increase in N (noise) and V (vibration) of the NVH mentioned in the video and it’s only at idle. You will only notice it if your windows are up and it’s quiet. As far as performance: You won’t really notice any difference unless you are shifting while at high RPM/on the track or during some spirited driving. As far as install goes I was able to go this with some jack stands, a floor jack, 18mm and 15mm wrench and it took me just over 7 minutes to complete (Made an install video for it on my YouTube channel is the only reason I know.) all in all I am very pleased with the purchase.

            Helps the shift a little bit

            I'm a bit torn on this part. Installation was pretty easy even with just jack stands and a jack, but make sure you jack up your transmission itself a little bit before removing the bracket to take the weight off of it. I highly recommend buying some grease to help slide the piece in. It firmed up my shifts a little bit, but not quite as much as I was hoping. The drone in the cabin is significantly worse now (I do drive a GT though), but it doesn't really bother me too much. I can't really complain for the price of this part. If you're looking to improve your shifter feel, I'd say it's probably better to go with the Blowfish Racing bracket instead, but obviously that's a bit of a step up in price. That will likely be my next purchase.

            Some increase NVH

            Well with all the mixed reviews I figured I’d spend the $30 and see for myself if it helped and if the NVH was unbearable.. First it took less than 20 minutes so if it becomes an issue I can remove it quickly. Second the shifts are much smoother and feels a lot better than before I installed it. Got on the car and no issues shifting high RPMs. If you can bear with the small amounts of noise increase it’s worth it.

            Whiteline shift mount insert

            Great product definitely helps when shifting, I have a completely stock car with just outlaw axel back mufflers. There’s a small amount of vibration but hardly anything to even worry about and after a couple weeks that even goes away a good bit. I’d definitely recommend this product especially for the price. Took 5-10 mins max to install with basic tools.

            Man Up Butter Cups

            After reading all the whining and complaining about the NVH from this piece I was a little apprehensive. After the install (which was laughably easy even with only jack stands and a floor jack), I took my 16 GT for a shakedown cruise. Is there increased noise? Absolutely. Is there more vibration. Yes, some. However, the shifter feel and shifts are undeniably more positive and firm. NO more stock mush feel in the gearbox. Mission accomplished as far as I'm concerned. Id love to know which of these sniveling, millenial, complainers have obnoxious ATAK or similar exhausts and think thats just fine, but cry about this being too much NVH. Silly. If you're a real performance enthusiast, this is a VERY tolerable increase in noise and vibe even for a daily driver. Great, easy, mod.

            Great feel

            Definitely more of a stiffened feel to my shifts, not as much flex as before. A little more vibration than before in the shifter but a great product.

            Garbage

            I should have known better... a $30 bushing that solves the majority of shifting issues. If that were the case the Ford people would have done it themselves. Made my car violently shake and jerk taking off in first gear. Took it back off. DONT WASTE YOUR MONEY!

            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.

            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
