Greetings, new member, hoping I can get some assistance in relation to an intermittent whining noise
when towing in my 2012 BT50.
Generally only occurs when I have been towing for some time and proceed to slow down entering a town or pulling up, whining noise comes in about 2nd and 3rd gears and then disappears. However I have had the noise present until almost stopped.
Have also noticed that the noise is still present when neutral engaged and can disappear if the engine is revved.
It is only intermittent but very concerning considering this is my 3rd Auto. It has done app. 40,000, vehicle has traveled 70,000.
Fan is a clutch fan. Noise is not evident unless towing and usually when weather is fine or I have travelled some distance.
Tow a Jayco journey outback, and camper trailer and have experienced this noise towing both.
Hope someone may be able to assist.
