Hi guys!
I have a whining noise in my gearbox and I don't know if it's normal or not. Does anybody have the same noise? I attached a video of this (sorry about the quality). In 1, 2 and 3 it sounds like in the video but in 4 it disappears. Somebody knows if I use some "oil treatment" or something like this it could help? I always use Castrol 20w50
Best regards!

what video's that then???

 

In fourth the input and output shafts are just linked, all the others use the laygear. It's probably related, but it doesn't narrow it down much.

The whine will be fine as its disappeared in 4th, called gear whine :)

The whine disappears in 4th because the torque load is taken off the laygear...

 

Unless its a straight cut gearset then it's your layshaft and bearings which are worn and starting to break up.

What you have there is a perfectly normal mini gearbox sound...

 

When you get a "WHINE" you will know about it...
