I started to get a clicking sound coming from the gear shift mechanism when shifting into 1st, 3rd, 5th.

Removed the centre console to take a closer look at the gear shift mechanism, and found that there was a half disintegrated thin rubber bushing between the gear shift mechanism, and where it connects to the gear shift cable.

Once the bushing is gone you've got metal to metal contact .....click..click...when changing gears. Not terrible, but annoying.

This must be a pretty common thing with 10 year old 6 speed Integras.
Anyone else come across this ?

I fixed it with a home-made rubber bushing for the moment. But plan to ask Honda if the proper replacement is available (without having to buy a new gear shift assembly).
