Prado 150 series – strange secondary noise to the engine

[BlairDub Lurker Find all posts View Profile Close BlairDub]

Hey guys. I’m new to Prado point. Has anyone had this issue or know of someone who has? When travelling at speeds of 90 km/h plus my engine makes a secondary noise. The only way I can explain it is if you imagine that you were driving a manual vehicle and you are rolling down a hill in, for example, third gear and as the car gains speed you can hear the engine revving. I am having this issue as noted above the speed of 90 km/h. I have been driving down the highway at 100-110 km an hour and have taken the car out of drive and put it in neutral and I still get the noise . At first we thought it could’ve been a transfer case issue, so I had my mechanic change out the oil but this has not helped. I’m hoping to be able to resolve this. It doesn’t seem to affect the performance of the car, but it is very annoying when driving down the highway which I do daily .

Tyres?

Yeah I’ve thought of that but I run A/T so there is a constant tyre noise anyway and when travelling at 90+Kmh there’s tyre noise and my other noise

There are couple of videos on youtube regarding high revs on smaller gear at high speed, which makes unusual noise at 90kmph speed. This is something related to the software. I would recommend to get it checked from authorised toyota service centre.
