{NB} Rattle in 6th and 4th

[Timmo]

My car has a rattle coming from the gear shift/box when in 6th (and to a lesser extent 4th- I.e. with the gearstick towards the rear).

It's not a loud rattle, it sounds similar to something vibrating in the glove box or stereo compartment (i.e. slightly plasticky rattle)- I haven't taken the trans tunnel cover off yet to investigate it but does anyone have any clues as to what it may be?

Cheers

I had a rattle like that but its my exhaust bushings they are worn so at certain rpm and load the exhaust hits the trans

Found the issue- Both rubber seals (the one which seals the trans tunnel from the cabin and the one which seals the top of the transmission) were cracked- When the gearstick was facing back, the crack was opened up letting gearbox/road noise into the cabin.


I've ordered both seals from Mazda (not exactly cheap though!) so that can be this weekends job.

Yeah ive done them, not cheap! But cuts down the noise and a lot of heat coming into the cabin. -if still rattling start checking exhaust shields bro.
Mine sounded like I had bloody maracas under the car!

Should be all good in terms of heat shields as there are none

Haha I did notice the muffler or some other part of the rear section of exhaust was knocking on something at the last track day though.
