TRD Short Shifter Rattle Noise, It's Normal?

[banpei]

I found an auction selling a spacer to allow a TRD shifter assembly to be mounted on top of the OEM retainer. The description (translated) is as follows:

Quote:This is an aluminium spacer to prevent chattering noise from TRD quick shift.
Assemble the quick shift using the normal retainer and spacer (image 3.4).

The chattering noise at high revolutions peculiar to TRD quick shift can be reduced.

In this picture you can see the assembly:

TRD retainer is about 1 cm higher than the OEM one, allowing a shorter throw. My suspicion is that either the cup and collar inside the TRD short shifter are brass or nylon and therefore rattle/chatter, or the retainer has some not-so-ideal clearances. Replacing the TRD retainer with an OEM retainer (plus spacer) would solve this issue.

If you need the spacer, you can find the auction here:

If the auction is gone, you could search for its title:
