Description

Whiteline’s Transmission Member Bushings replace the factory’s soft rubber bushings with more robust urethane bushings. This will result in reducing the amount of flex in the transmission support. These are going to be placed in the lateral, and the horizontal support of the transmission, and will ultimately eliminate the flex that is allowed by the soft rubber units in place.

Expect improvements in shifting, as well as in throttle response.

NOTE: Will fit Manual Transmission Only.

Slight Difference
OrphenCB 3 months ago
I installed these bushings a little while after doing the Group N mount and shifter bushings, so unlike others, I only changed these out instead of doing them at the same time as everything else. You'll notice a minuscule amount of added NVH; I mostly noticed a slight bit of added vibration in the floor. In terms of shift feel and transmission movement, it's also minute but noticeable. Shifts feels ever so slightly more crisp, and I can feel a slight reduction in transmission movement under harder launches. Is it an improvement? Yes. Is it 100% necessary? Not really. Though, if you've got the extra $50 and are swapping transmission mounts, you might as well do this too.

Why Did I Wait?!
CarTuned 8 months ago
I installed these bushings along with the Group N Transmission Mount and can say that together, these replacement parts are worth every penny. The car just feels better/more together, if that makes sense. There is an increase in NVH (about 10% noise and 15% vibration/harshness). Overall, it's not bad enough to make me want to go back to stock mounts and bushings.

Solid shifts

I had this kit installed on my 04 WRX, so I kind of knew what I was getting into when I bought this kit again for my 11 WRX. Nothing has changed, same great product, same driving results, and RSD with the great follow on service!

Great cheap improvement

So I installed all at once. (recommend doing all these at once) Whiteline Rear Diff Positive Power Kit Inserts Whiteline Gearbox Positive Shift Kit Beatrush Shifter Link Bushings Kartboy Rear Shifter Bushing Perrin Subframe Lockdown Bushings Hard for me to differentiate which product did what, But MAN, I can tell the difference, With a 2011 Fully built WRX (EJ257 block, 380HP) and no suspension upgrades, These products were amazing. PROS - Rear end is muuuch tighter/sticks to the road during turns and taking off from stop - Acceleration is improved greatly, and feels like you have more power - Feels like power is going into the ground more - Very little drive line shock - Shifting is solid - went from feeling like a semi truck, to a Indy Super Race car CONS The rear shiftier bushing, was hard to line up with the existing holes (turn a little by little on each side)

Great product
SpencerR 2 years ago
Installed at the same time as a solid billet trans mount in my '13 wrx, these were very noticeably stiffer than the stock bushings. Added some nvh but I'm sure most of it is from the solid trans mount. Super easy to install at the same time as the trans mount.

  • Q: what's the bag of grease used for that comes with the Whiteline bushings?  JW1 2 years ago

    Answer

    what's the bag of grease used for that comes with the Whiteline bushings? Will the bushings work with the 2016 STI?


    • A: Hi JW1, The grease included with this kit should be applied to any surface of the bushing that will be in contact with the sub-frame or mount (IE; generally the top and bottom) to prevent any noises when the transmission shifts side to side. We have been unable to personally confirm fitment of this kit on a 2016 model STI.

  • Q: 2015 Sti  jongsti 3 years ago

    Answer

    Any confirmed fitment for the 2015 STi?


    • A: Unfortunately, we cannot confirm fitment for the 2015 STI at this time. Sorry for any inconvenience.


      Brady R. 3 years ago
    • A: Yes, this kit will fit the 2015 STI.

  • Q: Crosstrek.   Rally of the Valley 4 years ago

    Answer

    will these fit a 5spd '14 Crosstrek?


    • A: These bushings are confirmed to fit 2012-2014 Impreza Sport and Base models, and they should also fit the Crosstrek, but we cannot guarantee fitment at this time.

  • Q: Install time?  nickgordon11172309 4 years ago

    Answer

    Would this require dropping the transmission to install? Plan on having these put on during my next oil change, how long would it take to install these by a professional shop?


    • A: These do not require dropping of the transmission.
