Whiteline Transmission Mount Insert for all 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019 and 2020 V6, EcoBoost and GT Mustangs with a Manual Transmission and all 2012-2013 Boss 302 Mustangs.

Ford really stepped up to the plate and hit a home run with the 2011-2014 Mustangs, and now 2015-2020 Mustangs, but fell short when they designed the transmission mount for the 6-speed MT82 manual transmission. This is where Whiteline steps in and offers their Manual Transmission Mount Insert for the EcoBoost, V6, GT and Boss 302 Mustangs, as a direct replacement and performance upgrade over the stock insert bushing.

The factory transmission mount has extreme voiding that allows for excessive and dangerous transmission movement which causes misalignment of the linkage mechanism. When that happens the end results are in the form of missed-shifts and binding under aggressive shifting or heavy-cornering. Whiteline has designed this simple, yet effective insert as a direct replacement for your factory transmission mount that fills those voids and improves overall shift engagement during spirited driving, which results in more precise shifts when they count the most!

If you're tired of grinding gears and missing those critical high RPM shifts, this Transmission Mount Insert from Whiteline should be the go to choice for your S197 or S550 Mustang.

*Fits factory 6-speed transmission mounts only.
*The insert bushing comes in black.

Take your shifting to the next level with one of the many different 2011-2020 Short Throw Shifters and Accessories offered by CJ Pony Parts.

Order a Whiteline Transmission Mount Insert for your 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019 or 2020 V6, EcoBoost or GT Mustang with a Manual Transmission or your 2012-2013 Boss 302 Mustang from CJ Pony Parts today!

Video Transcript

We've been pretty happy with the MT82 manual transmission in our 2013 Gotta Have It Race car, but we're always looking for ways to improve it. When Whiteline introduced this transmission mount insert, there was a huge buzz on the internet, so we couldn't wait to get our hands on one to see if this little part would truly make a big difference. Today, we're going to show you how to install the mount, and we're going to take it for a test drive to see how well it works.

The mount is a very simple part made of a firm synthetic elastomer material. What it does is it fills up the void in the factory transmission mount, making it stronger and less likely to move under shifts. For this installation, you'll need a jack and jack stands or a lift and pull jack, a 1/2 inch impact gun or 1/2 inch ratchet, 19 mm socket, 17mm socket, and safety glasses.

The installation is pretty straightforward. You want to support your transmission. You're going to remove the 4 bolts that hold the crossmember in, remove the crossmember from the mount, insert the mount, and reinstall the crossmember. We've got the transmission supported, so now we can remove the crossmember bolts. Remove the nuts that hold the crossmember to the mounts, and remove the crossmember.

Here you can see the voids in the factory rubber mount. Our insert is going to basically fit right in those openings to strengthen the entire assembly. I'm going to put some of the supplied grease onto the insert before we install it. Slide it up into place and it slides right in. We'll reinstall the crossmember, and the installation is finished.

I'd say the car shifts nice and feels real tight. One of the things we were concerned about was an increase in noise and vibration from the mount. Basically, it is almost a solid mount and anybody who's got a solid mount in their car knows a lot of vibration is transferred through. We're happy to report, it's pretty minimal. There's a little bit of an increase we can feel through the car, but overall it's very minor and something that you can live with on a daily drive with no problem.

Now we'll try a 2-3 shift. It's supposed to be one of the biggest noticeable differences with this bushing. Perfect, it went right in and felt real solid. The Whiteline mount insert worked exactly as advertised with no noticeable increase in noise or vibration. Our 2-3 shift especially is a lot firmer. Installation couldn't be easier, and should only take you around 10 minutes. You'll be back on the road in no time.

Vehicle Fitment

This product will fit the following Mustang years:

Rated 5 out of 5 by from Added stability I installed the Whiteline Transmission insert today. Transmission feels more stable. Somehow it made my stock exhaust louder like other people have mentioned, but I have not felt any vibrations in the car - neither through the floorboard nor through the shifter in any RPM range. To resolve NVH issues with the transmission insert (as stated in other reviews), here's what I did - - Made three 18.5mm holes in the center using a saw bit. - Made a 2" x 5" cut out of Shop Fox W1322 Anti-Vibration Pad and placed it between the cross member and lower mount. - Installed Blowfish Racing Shifter Support Bracket

Rated 4 out of 5 by from Easy, quick bang for the buck part Installation is incredibly simple and gave me a good reason to buy a new torque wrench. It makes an immediate difference in feel. I drilled mine with a 3/4" bit before installation. I can tell some difference particularly in mid-high rpm range in noise and vibration, but it certainly isn't a problem. At idle and lower rpm its not really a noticeable difference in vibration or noise. It's nice and I would recommend it. People bag on the M82 Trans but its a great gearbox and feels really good on a street car, and this just added some reduction in flex in the driveline. It's not a night and day difference but if you're looking at this part you should probably just try it.

Rated 2 out of 5 by from Whiteline Transmission Insert This is a great part! Whiteline really did make a bang-for-your-buck part here! It did improve my 2nd to 3rd shift feel. Feels much more accurate. However, I put it on my brand new 2015 GT and it is way too harsh and noisy for a brand new car! This is my daily driver, and although I'll get on it occasionally between stoplights, I'm not racing it. If you race your brand new Mustang, you'll love this. If the car is daily driven, it's a little harsh. I even cut a hole in the middle like CJ suggests and it was still too much, for me. Ease of installation couldn't be simpler. In my garage I put mine on ramps, put a floor jack to hold the tranny and had it installed in about 10 minutes.

Rated 5 out of 5 by from It Works After reading about issues concerning shift feel, figured for $30, I'd give it a try. Car was on jack stands anyway for the exhaust and springs, so just put a jack under the tranny, and did the job. Tried using water as a lubricant on the insert, with the idea that the water would quickly evaporate so that the insert would be locked in place. As in some other areas of life, realized that had to use a real lubricant to slide the thing in. Once I did that, it was all pleasure. Also installed the little $10 insert for the shift linkage attachment to the underside of the car body. Probably they both work together to get the final result, but the final result is excellent shift feel, and a lot more precision and crispness in getting the tranny into the preferred gear. A couple people who tried it (without me saying anything in advance) assumed that I had put in some sort of gonzo short shift kit.

Rated 5 out of 5 by from Works great, but.... When I first installed the mount my 16 GT had a race car vibration and sounded like I had upgraded exhaust. Sounded good but was a little much for everyday. I took back out after re-watching the CJ video and I decided to drill it. I actually slotted a little more that they did. See picture. I now have no vibration nor do I have the exhaust drone. Still shifts firm and no rear driveline clunk that it had prior to mount.

Rated 5 out of 5 by from For the price can't go wrong Added this into my set up with MGW 2nd gen & weighted shift knob and it made shifting slightly better at high RPM, for $30 you can't go wrong with that. NVH only noticeable when you're paying attention to it and didn't bother me. If NVH is a concern to you then I'm sorry you bought the wrong car. Would buy again.

Rated 5 out of 5 by from Wobble problem fixed! Excellent excellent bushing! Definitely well worth having installed! After installing the bushing, I took my car out for a test drive. I noticed a difference right away. Felt like it should have always felt... strong & sturdy with no room to wobble. I don’t know how Ford miss the boat & failed to install that bushing! Should be a stock part... installation was very easy and time of 10 mins. The bushing arrived on time delivered by UPS and was packaged very well! I highly recommend this product! Definitely save any issues that may occur down the road.

Rated 5 out of 5 by from Nice! Installed this at the same time as I installed a beefier Steeda transmission mount. And a Dynotech Drive shaft. All that I can say, is, what are you waiting for??? Shifting gears is so much more responsive. And easier too! Did a bunch of things to my car this winter. And just took it out for the first time the other day. I only noticed positive! People have expressed concern about noise and vibration. My car is super charged. And has headers to boot! If I was worried about noise and vibration, I would have bought a Prius!
