Ok here's the niggle.

The cars running really nice but with all this hot weather and the fact the windows are down whilst out and about Ive recently noticed a gearbox rattle/slap metallic noise, kinda like cogs meshing and taking up slack as they touch each other on over run when changing down into 4th and then into 3rd using the engine as slight breaking. (I'm guessing that's where the noise is coming from). Oh and only when the car has been on a run and everything is nice and warm does this sound occour.


There's no whining on acceleration or deceleration and the car has had new millers 75-90 gearbox and diff oil not to long ago along with a new exedy pink box clutch. The old oil I took out was dark but clean with no metal fillings or suspect looking sludge.


I have been reading on verious sites, pages and forums that changing the clutch to an uprated one can cause this rattle with some people saying its coming from the release bearing but I just don't know how true this can be.


Does anybody else have a similar noise or has anybody heard of this before? am I just worrying unduly.


The gear box is the Ty754 type which apparently is a harder and stronger box than the Ty752 type and by no means has my car been pushed hard.


Any thoughts or ideas would be greatly taken on board.
Car is still very drivable and ill continue to enjoy it but would like to know where it's coming from.
