Has anybody manage to figure out a fix for the gear lever
rattle that happens at high RPM (5k+)? Recently its gone from being a minor
annoyance to near enough unbearable, it’s starting to dominate the sound within
the cabin. A quick google shows im not alone with this problem and that over in
the US there is a TSB for it. Unfortunately the TSB doesn’t appear to solve the
issue and it’s just a case of luck of the draw. I would prefer just to do a DIY
myself rather than go through the pains of warranty.



For the record it has nothing to do with the gear knob
itself, I’ve driven with that completely removed and it still does the same thing.



Help before I saw off my gear lever


Cheers,Matt

My gear knob is so heavy it'll need a serious issue before it starts to rattle around. (Raceseng Slammer...) But even with the stock knob I have no rattles at all (maybe because I cant hear em around 6k rpm due to exhaust noise ?? :) )

My gearbox & level rattles/shakes very heavy if spinning wheels from stop in low gear. As it's at rear/abnormal scenario, that rarely happens, i simply don't care. Drifting in higher speeds and/or in higher gear there is way less of that.

I took my car in for a service recently, ive raised the gear stick rattle a few times now with Toyota they confirmed there still isnt a solution available.

Since having the rattle i have changed the gear knob to a slammer which has made no difference.

Thats right I'd rather saw off my knob than have an auto


I had a Raceseng topologi gearknob which weighed as much as a small moon and that made no difference. The gear knob and its mass has no effect on this rattle as its some part of the lever/linkage mechanism which is rattling.

adri-man that does not fill me with confidence
many could argue that I should live with it but I'd tell them to put a bag on bottle tops in their car and tell me its not annoying...

Is it easy to strip down? I may have a look myself, not saying that i will know more than Toyota but if I can come up with a non approved Toyota fix I dont really care.

The way mine rattles, it sounds like it *might* be the cotter/split pin that holds the shaft in the bushing at the bottom of the lever, or the retaining shaft itself. But mine doesn't sound like it's as bad as those described above.

I've been meaning to pull the thing apart to have a poke around, but I just haven't had the free time recently.

I've had mine at Toyota a few times and they came back unable to find the source of the rattle.

In the end I gave up and jacked to car up to have a look myself, it's bleeding obvious why it rattles!


there is a shaft that the gear leaver pivots on, there are 2 plastic bushes between this shaft and the gear lever, and there is a washer and a circlip to stop the whole lot coming apart.


All this stuff rattles.... you can fill it full of thick grease and it'll stop, for a bit. ideally a replacement poly bush with tighter tolerances would resolve it.


Or remove the circlip and run a die down the shaft and reatin the lot with a nylock.


I did wonder if you could pack the entire assembly out with teflon tape, but seeing as it's a hinged joint I don't think it'd last very long.


I *really* don't understand how Toyota haven't figured out what the issue is or how to fix it, as I spotted it as soon as I wriggled under the car.

Mr Slow, I owe you, this is the kind of response I was looking for. I was a little suspicious that it was the gear lever due to the fact that some of the US guys have fitted aftermarket shifters yet still have the same issue (Kartboy and TRD) and the fact that changing the whole assembly makes no difference.

Am i right is saying the area highlighted is what you mean? This is our gearbox apparently (google)



Is this room to run a die down the shaft? If you tighten a nylock on there it may put too much tension on the joint and make it difficult to shift? (purely speculating as i havent looked at it)

At least i know where to look now

@MattGT, yes, it's exactly that, there's not really enough room IMO to get a die onto the shaft, and to be honest I think a nylock would be too deep, you'd have to use a thin nut. For Toyota though they could manufacture a new arm to resolve it, or modify the gear lever to create more room etc.


@cliddell it's the entire assembly, the circlip does rattle some, but then so does everything else

I tried packing the washer out, but you need something exactly the right thickness or you can't get the circlip back in.


I did wonder if you can get a dished washer that's lightly sprung in some way. The OEM washer has a light dish to it



Replacement poly bushes are the best fix IMO, but I don't know if you can manufacture them thin enough to fit.

I suspect polyurethane might be problematic. A suitable machine shop could probably machine Delrin bushes that would work, but it would likely be quite expensive for what it is.

As usual there are probably a few different types of rattle.

Mine buzzed above 5k rpm since new and Toyota changed the whole gear stick shaft and it went away. However I have a new buzz again. They are going to change the shaft again, but I think this time it's just the knob cap that's buzzing.


Toyota did mention fitting different bushes for it to prevent it reoccuring.


I also have a different rattle from the gear stick when the engine is cold and you top the accelerator. This could be clutch thrust bearing wear maybe, though at 3 years and 27k miles I doubt it.

Mines getting worse and worse. I've had no luck at my local dealership. They logged a case with Toyota Europe but that's about it. At one point they tried to suggest that it was caused by my Cossy catback!

I think part of the problem, is that there isnt much of a fix.


The exhaust does connect to the gearbox. My H&S which is heavier and doesnt do it as badly.

Im fairly sure i read one of the Toyota fixes for this was replacing the plastic bushes with metal ones which should be a better fit with less potential for wear.

got a part number?


EDIT: thinking about it, there can't be a metal bush, it just wouldn't work as a bush then.

I got mine replaced today for the second time. The whole shifter shaft.

It buzzed badly from new above 5k. They replaced it. It started to buzz slightly again after a few weeks. I reported it. They confirmed it.


Today they replaced the shaft and uprated the bushes. It shifts better than ever. Glides into 1st and 2nd with a flick of the wrist.


Obviously I can't confirm yet if it will start to buzz and rattle again in time.
