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

  • 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.

    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.

    Huge difference

    Super easy to install and the difference in the drive line is amazing. Takes all the slop out and no more missing gears. Decreased the extra noise that I had from installing short shifter. Awesome product.

    another great whiteline product

    This is a nice low budget mod and helps keep the drivetrain a little more rigid for those occasional spirited rides.

    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.

    Mustang GT 2013 shifting

    I recently put in my 2013 GT a Ford Racing Short Throw six-speed because I got tired of nailing the car to the floor to only have the shift from 2nd to 3rd skip me into 5th. Well... the shifter was a great addition, but there were times still that the shift wasn't quite as solid. I was told by Ford Dealer write up guy to put in this bushing insert. The container it arrives in is actually called a Shift Kit. It replaces the rubber mount and really solids up the drive train to avoid too much torqueing. Now... I have no issues what-so-ever in my power shifting through the gears. It seemed to really "true-up" the movement.
