Short shifter rattling
 

Tried searching and didnt see anything about this and havnt heard this exact issue before. Just in the last couple of days I've noticed a rattling sound from my shifter. It's only in first in the higher rpms, and more prevalent under harder acceleration. I've had the RP short shifter for about 8 months maybe. It's not the vibrating/hum that many describe, as said it's definitely a rattling sound. Is this anything to worry about or just the shifter moving a little?

Is it the shift knob? The metal on the top of my oem knob began to rattle so I dumped it for the Voodoo knob. Problem solved.

i have this problem in 2 4 and 6th. =\ dont know why and havent found out through searching either. it seems to be fine but the rattlings a little annoying.

not the shift knob (at least I wouldnt think so..). As I said, the only time it happens is high rpms in first gear only... no other gear does that (well, first, second and third are the only gears it'll matter with most the time anyways, but it doesnt happen in 2nd and havnt really tried in third since the sound started). It still shifts fine and everything, but if it's the start of a problem I figured I'd ask just in case. Thanks for responses... if anyone else can think of anything, ideas are appreciated!

having the same issues I believe. Just installed it today too. =(

i dont know if this is true for the rx8 but the short shifters rattle on certin trannys in the rx7's. i have one in both my rx7's and one of them rattles but the other one dosent. no one has figured out what causes the rattle.

If it's really rattly and feels loose...pull it and check the bushing on the end

feels tight as can be. just rattles at high RPM's in 2nd and third. Not terrible, and only happens under hard acceleration. Maybe the plate isn't screwed down enough or something and it just hits some resonance with the metal? I have a voodoo knob and I don't think it's that.

I forgot I had this problem/started this thread lol... mine went away... dont even remember when...

I'm hopin the same thing happens to me. haha

Dump the Voodoo knob. The shifter was designed around the stock knob, no development work was ever done with others. People who use aftermarket knobs have mixed results. We can't go around testing all the combinations. I like the feel of the factory knob myself. Plus I live in a sunny place and can't imagine getting into the car in the summer and trying to use a metal knob that is baking in the 100+ sunshine.

Not sure how much this will help others but I found it interesting. I have the voodoo knob and have no issues with noise (that i can hear).

The other day I was cruising down the street looking for an address when I picked up a piece of paper with the address on it. The light turned green and I had the paper in my right hand and started shifting. When the paper touched the knob it amplified a very odd "rattle" noise from the shifter. The noise is not audible to me unless the sheet of paper is resting on the head of the voodoo knob.

I've done all the tricks people have posted (cutting the green liner down a bit, making sure the seem is facing forward, etc). If you're getting a noise from your shifter + knob setup I would follow RP's advice and try the stock knob.

As far as the knob getting hot in the sun and burning your hand... with great pleasure (the shifter) comes great pain (the toasty hot knob) :)

Unfortunately my car was bought at auction and did not come with a knob at all, so I opted for the voodoo over the expensive stock knob, I can deal with the noise to be honest, and it has not happened since my last post. I love the feel of the whole combo to let some noise bother.

GREAT PRODUCT RP

That deal with the paper is just plain Voodoo.:SHOCKED: :Wconfused

I know, I know, holy thread resurrection, Batman!

Anyway, I just installed a RP short shifter, and am experiencing the same rattle. Almost sounds like a loose nut so I took it all apart, retightened all nuts, that didn’t help. Stock knob. Happens with or without the console mounted. Anyone figure out why it happens?

Loving the shifter btw, never imagined it’d make such a big difference, which is why I left it on the shelf over a year before installing it...

Rattle happens only above 8500 rpm, and is not noticeable unless I’m accelerating. Easily noticeable in first, less pronounced in 2nd, even less so in 3rd.
