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.

    best bang for buck til new shifter...

    The dreaded mt82 shifting lockout. I read online this would be the quick fix till I purchased an mgw shifter. Cheaper too. Seems to be working so far and very easy to install. People have complained about NVH but haven't really noticed tbh. I drive 2013 boss 302 w/ the sidepipe baffles removed so probably covers it up a lot.

    Whiteline Positive Shift-Boss 302

    Very simple installation, about 10 min. max with a lift. Did not really get the vibration others mentioned, shifting is much better.

    Must have mod.

    Modifying the insert by cutting off the bottom tab and installing it in the transmission mount was a breeze. Even on ramps. If you have access to a lift even better yet. The bushing insert, the Ford Racing/Barton short throw shifter and the two post shifter bracket makes the MT82 trans as good as it going to get. Shifts may still be slightly notchy (mostly when trans is cold) but you will never miss a shift again no matter the RPM's or curve your on. With the bottom tab cut off you will not feel any vibration at the floorboard or steering wheel. There is a slight increase in sound that makes it feel like you swapped out the exhaust. Don't hesitate this is a must have mod even on a daily driver.

    Shifts are noticeably smoother

    Ordered this product because I continuously got locked out of gear at 7200+ RPM shifts. This insert for the trans mount helped out quite a bit. Installation was about 20 minutes including the time it took to jack the car. Once in, even just driving, casual shifts were a bit more solid and smooth. It did help to get me in gear at 7200 RPM, but I have already ordered motor mounts which will help solve the problem further. For what you pay, this item is a great improvement. Keep in mind that NVH slightly increased, most noticeably around 2100 RPM. For me, the sound was an added bonus. After all, its a Mustang.

    Must have mod

    After buying my 12 GT over a year ago, I've had many denials into gears both while driving and trying to get into first gear at stops. I did some researching and everyone recommended a short throw shifter so that's what I bought. I bought the MGW shifter which replaced everything. It helped to a degree and brought the benefits of a STS but still got denials. I just lived with it for a couple months not knowing what to do. I saw this product and figured I would give it a try. Well it's simply amazing! Everything just clicks right into gear. No more denials in any gear or at any speed! This insert is definitely a must have mod, even before a STS! Install was pretty easy as well! I can't comment on any added NVH from the mount because I put on new Dunlop z2's at the same time so they add noise as well. Hitting all my shifts is definitely worth it.

    GET THIS NOW! But, make sure you get the $59.95 AM Whiteline Transmission Mount as well. These two parts together make the shifting accurate, tie the drivetrain together, and give better handling as a result. I know, it sounds crazy, but it really does work. But, do BOTH in the install. Great products. I don't miss shifts anymore, and my GT handles better. NVH is about 5%, and a small price to pay for all these two do.

    Butter-shifts

    The install was super simple and easy. I got it done in my garage with the car on jack stands. It took me about ten minutes. The difference in the shift from 2nd to 3rd at high RPM is night and day. I am using the stock shifter and it is so much nicer now with this part. The only drawback is the increase in NVH. I expected this to increase but it vibrates through the floor pan like crazy when I accelerate hard and I can even feel it through the steering wheel. It's no big deal on the track but on my daily driver I have a feeling that it is going to get old really quick. We'll see.

    Excellent product for the price.

    For guys that miss shifts from second to third this mount is for you. Longest part about the install was jacking up the car. Easy 10 minute install after that. Alot of guys said they got NV i didn't gain any at all. Car goes in gear easier in every gear and when banging from second to third is so much better. I really recommend this product for someone looking for a cheap part for there car.

    Best $31.32 I ever spent!

    I cannot believe what a dramatic difference this simple part makes. It works exactly as advertised. I am stunned .The shifts are positive, and smooth. It feels like a different shifter. I read the comments about increased NVH after installation. I did not notice any increase. However prior to installing . I did trim about 1/4" off the flat center section prior to installing as many suggested so that may be why. I suspect that if it is not trimmed the center section which protrudes from the back the mount and contacts the crossmember causing the increase in NVH. Installation was simple, I installed it on my back in my garage with a floor jack and jack stands. It took less the an hour. Greasing the bushing before installation is a must. Great Mod. Highly recommended!

    BROUGHT A SMILE TO MY FACE!

    I do a lot of research on any product I add to my 2014 GT. Installation took about 15 minutes using my ramps. Interestingly, the issue of NVH was minimal. It actually reduced some of the noise from my Ford Racing Short Throw Shifter. I only felt a little vibration in 2nd and 3rd gear between 2000 to 3000 rpm. But, when I test drove it...........WOW! Best functioning stick shift I have ever owned; and I have owned more than 10. 100% perfect, hard throw, hammer down, flawless! If the minimal NVH bothers you, maybe you should be driving something else.

    Works, but not for the street

    I purchased this after reading an article in a Mustang publication. Very simple to install and it DID make the shifting more positive. HOWEVER, in the article it says you get some NVH (Noise, Vibration and Harshness). The first time I drove it after installation, it vibrated the car as if I had a bad u-joint in the driveshaft. Not worth it for daily driver. Great for racing.

    mod of tranny bushing

    ok read lots about this piece doing its job but adding some un wanted NVH. So I cut 1/2" off the length of the rectangular middle section and then drilled 5 holes in the middle section length wise. I then greased up the unit and into all the holes. It slid right in and made a nice differance with the noise i heard from my Barton Shift bracket install. It really quieted the mechanical linkage noise and made the shifter feel very smooth and direct. No more missed 2nd to 3rd shifts and it just feels solid! SEE PICTURES

    As Described

    Works exactly as described and like others have said, it does add NVH. When I first drove after install, I thought I had done something wrong becuase the NVH was so much more than expected. I've done some surgery on the bushing and maintained 85% of it's intended purpose of the shift improvement and cut down probably 95% of the NVH. Of course it now it doesn' even resemble the piece I ordered.

    Easy Install

    Took me about 45min to install this. My main concern was n/v/h, but it is very minimal -even for a daily driver. Up and downshifting is noticeably smoother and the driveline just feels overall a bit more solid. Great upgrade for the price.
