Ive been hearing a whining sound from my 2010 alto for the past few days. It whines only in 5th gear at speeds above 60kph and only when pressing the accelerator. If i release the accelerator or press the clutch, the noise disappears(i.e no noise when coasting in neutral). what could it be? I innitially thought it was a wheel bearing issue but a bad wheel bearing should be noisy irrespective of the gear selected and there is no noise in 4th gear even at 100kph.

Searching around on google ive seen that low gearbox oil level would potentially cause whine/whistle sound in 5th gear and 5th gear is usually the first to be affected by low oil level. I checked the car thoroughly but could find no leaks. Ill get the gear oil checked tomorrow by a mechanic. Can u suggest any other checks besides opening the gearbox? my car has done just 42000kms.
