Exclamation Knocking from engine/transmission area?

Hi all,

I tried searching for clues as to what this would be, but wasn't successful.

I have a 05 6MT with 82K km on the clock. This started happening about a month ago when I was driving. There is a knocking sound (almost like a diesel engine) at low RPMs when I shift between 1st, 2nd and 3rd gears and it goes away when I'm into the higher gears and rev ranges.
- the rattle is also present after long drives and I park the car running, I will hear a rattling sound from underneath the driver/transmission area.

The oil is due for a change soon - about another 1K km before it's required to be changed. The oil levels are at or around full (last I checked)

Any ideas what this knocking and rattling could be?

Thanks for your time and expertise

Does the noise go away when you depress the clutch or any action with the clutch?

If so it's your throw-out bearing

Get in the car, turn it on, open the door....

Push the clutch in, and Listen. if you hear the noise go away or minimize it's the throw-out bearing.

3 different places...

all under 35.00


But the service/labor is where it's at.

The transmission needs to be dropped. and 8 times out of 10 you should replace the clutch while you're at it (that way you avoid the charge for dropping the transmission twice).

I dont think it is...

Clutches cost depending on manufacturer and level of performance.
