3gear Scratch

[CTR]

Hello,
When i put in 3 gear at high rpm up to 5500rpm you can hear a little "scratch"..
Already done the gearbox fluid ( 75w80 ) with an additive..
Does someone had similiar problem or know what it is?

thanks

I assume when you say 3rd gear" scratch "you mean " crunch "?
It seems like it's quite common.
If you search on here or Google Clio 172 3rd gear crunch you'll find alot of information about it.

Don't put any friction modifiers in, just 75w80 GL4 spec.
