It fit semi-snugly into the shifter before I lubed it up. There were no obvious-by-feel gapping issues. The insert slid smoothly into and out of the shifter without effort. When I put this hot mess all back together I'll grease up the bolt as well as the sides of the shifter where it mates with the linkage and we'll see if that calms it down.

And yes, all of the above statements are also relevant to any sex acts involving yall's wildly-varied yet equally disgusting perversions - looking at you, Mike/James aka the poor white man's version of Mike Jones.:wtf2::stirthepot:

?When you talk about Mike/James. You mean this?

I learned it from you. I hear wind is the only sound you can make anymore.

i'm anxious to see if this works

Me too.

I greased everything up. The insert was really tight, but the bushing had a decent amount of play. It’s too early to tell, but I drove for about 10 miles and did things that would normally cause the rattle, and it’s quiet so far. :ugh2:

Thanks. Keep the updates coming

Just ordered a carbon fiber shifter surround cover for the coolerworx.

I like it; but won't your hairties fall through the slot? I'd def buy it if it had a much smaller boot covering the gap.

Thats clean, I like it.

soooo back to that rattle... that solved now?

Sure, why not?

I'm going to take it to my local auto upholstery shop and see if they can fabricate a short (maybe a couple inches high) boot to cover the opening. Maybe make the part around the shifter shaft elastic so it won't slide down

Thrashed on the car all weekend with no rattle. Before, it was worst when punching revs north of 6K or tooling along in 3rd or 4th gear. Now it’s quiet except for some transmission noise in the high revs which I would consider normal for this shifter, given how it’s mounted.

Should also add that the m-tec shifter springs made a noticeable improvement in feel. Because the lever is so long it always felt sloppy with a heavy shift knob, but now it’s nice and tight, even with a 500g Raceseng.

Do you feel comfortable enough that I can get back to coolerworx and tell them it cured the issue?

I’m convinced it’s fixed in my case.

I'll let coolerworx know. We'll see what they come up with.

Curious about the shifter springs. I have a raceseng knob I was intending to use with this shifter too.

Can you clarify which part you had to grease?

I bought this shifter last year but ended up selling it since the rattle was driving me crazy while I was DD'ing my Z. Currently running a Torque Solutions short shifter with an extension and overall feels like crap compared to how the Coolerworx felt.

Thinking back, I recall greasing the bolt to connect the shifter to the linkage but maybe the rattling could be caused by the lateral play from the insert hitting the linkage when installed? Forgot now snug the insert was.

I will buy this damn thing for a second time if someone found a solution for the rattling :rofl2:

Look at post #137. Also, Coolerworx contacted me this morning and they will be redesigning the insert and let me know when they're available.

Yep, I saw that photo. I just didn't think that greasing the insert would have such a heavy impact since it's such a tight fit. Wasn't sure if it was just the whole insert being greased, or just the portion of the pin that inserts into the shaft. Can't remember if my pin had an o-ring or not but that could've been it.

Glad to hear that they'll be re-designing the insert but I'm not sure when v.3 would be available in the market. Definitely keep us updated!

So I ended up ordering my shifter a couple of days ago. Here's to hoping I get sent a revised version with the fixed part.

By "available" i assume they mean "we'll ship this out to you for free" ?

This damn thing was not cheap and I'd sooner sell it to JAR than pay for a fix they should have thought up in the first place.

Also, mad reps for running point on this.

Is it finally fixed!?! Can I buy one now and not fear I blew 600 bucks on a rattling pos!? Yay!

Took the Z out for a spin after a good grease job, had no rattling. Dodnt go past 3500 rpm tho as it's icy af out, I'm running summer tires, and the clutch is precisely 1.1 miles old.

I'll let Jar know when coolerworx contacts me about the new inserts. I'll ship one directly to him so he'll have it when you send him your shifter. :tup:

Fight me :rofl2:

I was under the car doing the diff bushings/cover/brace so figured I'd do this as well. I ended up using a spare o-ring I had leftover after swapping my injectors (took a bit of persuasion but hey....) and a bunch of grease, but the rattling 'seems' to have disappeared. So we'll see...

Heads up though: for anyone expecting Coolerworx to replace this free of charge, good luck... I'll leave it at that.

Yea lol. Coolerworx website is garbage and same with customer service 90% of the time. I'd say if you don't order a whole new shifter you'll have to get an O-ring yourself and fix it lol, which is probably the easiest way anyways.

Just ordered mine through SOHO. Hopefully when I get it I don’t hate it!:yum:

not fixed lol.
but I got the o ring with mine and its all lubed up. it seems like the reverse lockout collar is vibrating in 3rd and 4th and sometimes 2nd. anyone have this?

After installing the o-ring and greasing the insert, I haven't had any noises. Before, it would rattle in 3rd, never noticed in 2nd or 4th.

Any updates on whether revised inserts were put into production for the Coolerworx shifters or any reviews if it solved the issue?

Nope. Here's the correspondence I had with Coolerworx. I don't think they give a crap about fixing the issue.

Thanks for sharing that man, sucks that they didn't bother to fix it basically a whole year later :rolleyes:. Any recommendations for the type of grease that would work to remedy this issue?

Yeah, they're pretty useless. I haven't done mine yet but I think white lithium grease would work well.

Awesome, thanks man. Hopefully they address it at some point down the line:ugh2:.

It would be nice, but doubtful

Like Patrick said... they're not going to. Enough people buy it and don't complain so there is no need for them to fix it.

I'm still waiting on my red reverse lockout cable that Donatas promised me for helping them with all the measurements and test-fitting but yeah, I expect pigs to fly before that happens.

However for the fix, I used white lithium grease. Any decently thick and long lasting grease should work but make sure to use a lot.
