Perrin Rear Shifter Bushing Install
 

This DIY guide can be used for other vendor's bushings. I decided to purchase the Perrin based on my good relationship with @PERRIN_Chris.

@cobrabyte, @post_break and myself had a good time replacing bushings around our gearboxes. Much appreciation for the lift and garage space! Good times learning about our cars. @cobrabyte was also a good hand model LOL

Before we start, lets do some feedback. Out of all the mods I've done, arguably the best mods you can do are
+ Gearbox fluid change ($60 - http://www.ft86club.com/forums/showthread.php?t=19218)
+ Rear shifter bushing ($40)
+ Transmission bushing ($40 - http://www.ft86club.com/forums/showthread.php?t=19782)

It's very inexpensive, and goes a long way to remove the notchiness in the gearbox. For me fluid alone wasn't enough to remove notchiness, cold and warm. Shifting also felt very sloppy. Downshifting 3-2 was impossible without feeling that ball breaking cringe that makes you cry alone in the corner.

Now these things are possible. Throws are precise and the gear lever just goes where you want it to go. Notchiness/crunch noises are pretty much gone.

Not hard to install if you have a lift. Could be a challenge on jack stands. This $130 goes a long way to improve your confidence and precision in shifting. Talking about night and day difference.
@PERRIN_Chris: My only negative feedback was that washers were not included in my package. Not using them, the polyurethane started to eat your bolt head! Luckily we undid the bolt and found washers lying around in the garage. @post_break also did not have washers in his package, he used a few leftovers from my headerback install.

I do not have any knowledge about if this helps automatic transmissions. I am not responsible for any damage as a result of this modification. Remember to be safe!


Installation Steps

Raise the car. A lift makes this 100x easier, but if you use stands, please lift the entire car onto stands to keep it level. Refer to @GrimmSpeed DIY here http://www.ft86club.com/forums/showthread.php?t=10111

Finished!

I have the Perrin bushing and personally I think the inner diameter of the whole is too big which could result in actually a sloppier shift. I won't install mine.

Thanks! :thumbup:

doing this ASAP.

what are you basing this on if you havent installed it? mine went on snug, and improved feel.

what do you believe the ID should be?

subbed

I was waiting for this DIY. Thank you! did you take a side by side comparison photo?

One side of the ID hole of the bushing that you slide on is bigger than the other end. ;)
This is the same install for the WRX and STI and it does clean up the sloppy feel.

Great review! The kits are supposed to come with 2 washers, sorry about that! I'm having all of those kits checked to make sure they're in there.

So let get this straight... you bought it, received it, then took it out of the package only to say "yea that hole is too big" and set it aside only to come tell us about this miraculous discovery you've made?

Thank you so much.

The part works just as advertised and is a quality piece. I even got both washers ;)

:thumbdown:I installed this like 30 mins ago and I don't like it at all.

The shifter now makes excessive noise - whenever I put it in gear there is now a winding noise. Also, at low rpms you can hear this winding noise. In cabin noise is obnoxiously loud.

When I downshift the winding noise increases significantly and has an extremely large amount of resistance compared to stock; as if I am forcing the gear in. At one point I was worried that I was damaging the gears, so I left it in neutral and braked.

Maybe I'm the only one with this issue, but I'm going to get it removed.

Also, Yes I have it in the correct orientation.

Sorry to hear that, bro

I definetely love my Perrin rear shifter bushing and there is no extra NVH noticed in a month time... Just pure shifting pleasure

Yea me too. I was so excited.

Did you support the gearbox with a jack/lift during install?
Are you sure the driveshaft/propshaft was bolted back in correctly?

This sounds nothing like a bushing issue - I'd get a professional to check it ASAp

so far sounds like the only one. its a simple install.

post a pic of your install please. that sounds all wrong. Whatever happened i suspect will continue if you reinstall the old part but DO let us know how that goes

something went wrong in your install I think. The part locates the rear end tang in the same location and orientation.

Sorry about that, it sounds like something is off for sure. There will be a little more vibration, but it's far from being obnoxious or loud.

One thing we'd like you to check is the metal sleeve inserts in the bushing. Do they seem like they're longer than the bushing? If it's not that, maybe something wasn't tightened up?

I did the whiteline kit at the same time and I assure you that it was supported and everything was bolted back. My friend owns a shop we did it together, trust.

Like you said simple install, could not be simpler. The only hard part is when working on the floor without a lift. As I said before, the orientation is correct.

The orientation is the same as the second to last picture from op, where the bushing mountain is on top and the bulge is facing the gearbox.

I'll check the metal sleeves today, prior to installment I believe the sleeves were not longer than the bushing.

Interesting, first I have heard of this. I have one ready to install when my break in is over and modding begins. Definitely interested to hear how this turns out.

Hiya!
I'm currently doing the install. I've take out the OEM bushing and I'm about to install the PERRIN bushing.
One question. I undid the clamps that were holding the drive shaft, but when I undid them the driveshaft went down towards me about 4-5inches(it did not fall completely) and I heard a kind of vacuum sound. The shaft probably went out about 3-4 inches but I managed to catch it before it came out completely. Would there be any problem with that?(im a newbie)

Checked the sleeves and they are fine, everything is fine. I went down under to do an engine, trans, diff fluid change. After the fluid change the shifting felt a lot smoother, but still pretty notchy on 5th and 6th gear. Also, the noise level did go down, but it's still louder than stock.

The drive shaft connects to the gearbox and diff mechanically so that vacuum like noise shouldn't be because of that. Are you saying your shaft came out like detached? Ours was able to fall a few inches and sit on the exhaust

The shaft came out, probably a couple inches. The 'bent' part of the shaft went down about the same level as the exhaust, it didn't fall out though. I put it back in and finished the Perrin/Cusco install I just did, no CEL lights and no drips. I hope everything is A-OK.

Let us know how that goes. I'm thinking about installing one myself.

It's pretty good mod. Shifts are real nice and smooth, less 'lurch'.

Installed it yesterday along with the whiteline insert, but didn't notice any real difference from stock as far as shifting goes...

I guess we are all sensitive to a different level. Both wife and I noted a post install improvement.

Installed mine last night. I found using a longer extension on the socket was best to tighten up the bolts on the shifter bushing.

You can move around the small shaft a little from the gearbox to help align the bushing as intially it was a little close to the top of the body of the car.
I also held the tail shaft with one hand so as I undid the bolt holding it to the body it didnt drop suddenly and possibly strip the thread.

They are not kidding when they say it is a tight fit to get the new one on but once again I did this on my garage floor with wheel stands etc.
I did invest in a $40 sled to lay on from super cheap. I have never had one before but was gold for this job.

I also bought two small rubber mats for my ramps to go on as my garage floor is painted and were consistantly slipping tring to get the car up the ramps. I knew I would be working on this car alot so I bought extra long ramps as this car is quite low as stock. However the ramps were still not long enough and had to put hard wood sleepers before the ramps to stop the car scraping on the front.

After the install I jumped in the car and moved the gears around to get a feel of what it was like. ...... Well I did think it was still a little cluncky and not really what I had hoped.
But in the morning when I drove it to work and soon as I shifted in second gear I new that this had done the job. In fact it feels completely different.
I think it is excellent compared to stock. Much smoother through the gears, really nice you will like it.

6th gear did seem a bit tighter to me and did have to guide it a little more than before but still smooth just a little stiffer than the rest of the gears.

Hope this helps anyone else deciding to put this in. I think its well worth the effort and excellent mod. Well done Perrin. :thumbsup:

Just bought mine :D Looking forward to installing it and feeling the difference :D Going to do the Whiteline parts KDT922 - KDT926 at the same time whilst im under the car.

I really like it. I had a friend complement the car on how good the gear changes felt. Job done.

Just installed mine earlier along with the Perrin Transmission Support Mount. Definitely less slop in the shifter and improved feel. Just another satisfied customer.

improved feel! Thanks! awesome writeup!

Another awesome write up. Thanks!

I did the Perrin shifter bushing and trans mount this weekend. I have one suggestion to put in bold in your instructions. PUT VEHICLE INTO NEUTRAL. I struggled for 20 minutes to get the damn bushing on the end of the shifter rod. Then I figured I might be able to move the rod a little more if it's in neutral. Low and behold, the whole drive shaft dropped down about 3 inches. Then I easily just popped the bushing onto the end of the rod.
Another quibble with the trans support instructions, there are 9 bolts to remove not 7 as stated.

Anyways, there is definitely more gear whine but not really any more vibration.

Got this installed last night. Thanks for the DIY.
The shifter does feel a lot more precise and crisp.

However, the notchiness feels very odd now. Whereas before the bushing I would feel one big notch when shifting into gears, but now it feels like 2 small ones. I can pull the shift lever half way into gear and hit a wall then keep pulling to get entirely into gear.

Is this normal?

Installing mine right now and I CANNOT STRESS THIS ENOUGH. Doing the install on jack stands and tried to get the old one off before reading this post, which was an exercise in futility. Found this post, popped it into neutral and it took me about two seconds and almost no effort to get the old one off.

Both things have been noted and fixed in our instructions! Thank you for bringing both things to our attention!

Hey bro I installed mines today. Took about two hours. Worked on the floor. I gave up on the rotational part. I tried for about an hour and could not get it to turn. So, I just slipped it in in the correct orientation and then re-both everything back in.

Review: I do notice a difference shifting up and down. I feel a bit more confident.
What gave me a problem was bolting it back together. Awkward position.

Did mine yesterday and was a pain to fit the bushing lying on the garage floor with jack stands. Didn't rotate it too and fitted in right side up with considerable pushing.

I notice a mild hum now when driving, with slight improvement in shifting.
