Cabin noise.. tranny issue?

maurim3 · 03-30-2012, 10:20 AM

Guys Ive had this anoying noise on the car since i bought it. It looks like tire noise, It has some crappy tires now. So to rule the tires out i drove the car on the sand, but the noise persisted. Now im thinking its the tranny bearings or something like that. (cause its actually a noise resembling a bearing noise from under the car) So I have the tranny taken down and disasembled today. And the mechanic now says that the transmission is perfect. Like brand new... So now Im f..cked ... what else could it be.

It's most likely normal. The Z has a very loud tranny and clutch/flywheel.

If you want to verify for yourself, go to a dealer and test drive one of the Z's. If it's the same, there you go.

You actually had a mechanic disassemble your transmission????

yes... We lifted the car and heard a noise coming from the transmission. So it looked like bearing noise. I also hear the road noise everyone is talking about. When you go on different surfaces. I got that. But this is a diferent noise on top of that noise. It definaly feels like a bearing noise.

Ive read the tread, but its not that.. the noise increases as I go faster. Its not the throwout bearing.
