I've searched and saw one or two people who said their rattles cleared up with an engine torque brace. Anyone else experience this ??

I have a B&M short shifter that just went in and has a slight rattle, but enough to annoy me. It is not rubbing anything in the tranny tunnel and I've read through this http://www.mazdatrix.com/shiftrat.htm

Also, I'm wondering how true it is where some people say they've switched from B&M to say Mazdatrix and the noise went away. According to the Mazdatrix link above, ALL of the shifters they tested randomly rattled.

Any info. is appreciated.

 

My B&M rattled with a Razo shift **** and engine brace; probably too light in mass and so resonance frequency matched?

switched to OEM shift **** and it reduced like 80%. There is still gear whine you can hear though. The action of the B&M seems crisper and alot quicker than the Mazdaspeed one. But the downside is the rattle and gear whine.

 

Well, I've talked to several people who have the B&M with no rattles. I did switch back to the stock shift **** and still rattles. Thanks for the info. on the engine brace.

 

I have a Feed brace and a Gotham short shifter with a stock ****. Mine rattled for a while but eventually went away.

 

Really ?? I've read this too, but how long did it take for it to go away ? My rattle is not extremely loud. Just a bit of a rattle in 1st and 2nd gear, then a bit in 5th as well.

So are you saying that you have Zero rattle now ? Thanks R1.

 

no rattle here...

 

My B&M rattled like crazy when I first got my car. I realigned my powerplant frame and it fixed it completely. I think that's all you need to do. No need to spend any money...just time.

My Mazdaspeed short shifter vibrates more than the stock one, and whines above 100mph.

 

Did you guys mount the plastic or aluminum bushing on the bottom ball of the stick on your B&M's or Mazdaspeed shifters?

 

B&M shifter, RX-8 shift **** and feed-style torque brace and it rattles only at certain rpm while accelerating. I reused the plastic bushing, somebody said if replaced with a new one it'll stop rattling but I haven't done it yet

 

Sonny, can you briefly explain how you did this ? Thank you.

 

use GREASE on the lower end of the shifter bushing, and then submerge it in gear oil in the shifter boat

 

Here's my thread on how I fixed the rubbing.

Looks like rattles is hit and miss on shifters..

Anyway the ETB wont help with the rattle..

 

I should have also mentioned that I put a new plastic busing in as well.

 

what's ETB?

 

Engine Torque Brace

 

Mines rattles with stockers! I aint complaing! jokes!

 

When I installed a short-shifter in my Mustang GT, I had a rattle as well. Turned out it was the aluminum **** I installed to go with it. To fix, I wrapped the threads on the shifter with a little bit of plumbing pipe tape. Try that out and see if it does the trick.

 

I really never saw why they rattle. I cant speak for the B&M style since its a different design, but like the Mazdaspeed and C`s if you put it together right make sure your mounting bolts are actually seated not only just tight and the gaskets are in there and you have the proper shift ****, i dont see why it would rattle..
