Super strange Transmission noise - Toyota Yaris Forums

Hello Folk! Sorry to bother you, but i'm experiencing a super-strange problem with my late 2010 Toyota Yaris 1KR-FE with 5 gears manual (yep, i'm european).
It's super hard to explain, that's why i will upload a video ASAP if requested. That's what's happening: when i reach an high number of revs (over 3500-4000 rpm) i hear a strange "cartoony" noise that disappears all by itself ( around 3-5s). Sometimes i hear it when i change gear but, most of the time, it's on the high revs. It doesn't happen all the times, but it's worrying! Personally i suspect a gearbox\transmission issue. My Toyota has 54 000 km (about 37 000 miles), it happens with ALL the gears except the 4th and 5th. I have NO problem inserting the gears, it's all fluid as usual. The problem started around december when i changed my brake fluid, coul be related? Hope you will help me sorting this out,

Andrew
