Lexus LS460 Transmission Concerns

[SH20]

Is there any truth to the comment I heard  today from a trader  who suggested that the 460  can develop some low resonance sounds  from the transmission which manifests itself as a low hum in the cabin for want of a better word at speeds around   70-80mph?  Urban myth or anyone heard/experienced something similar as I experienced it today on the M1.

Had my 2007 460 for 4 years (100k miles), have been trawling the internet for several years, spoken with other owners over the years, have never heard anything about this.

I've had mine since 2013 and don't recognise those symptoms. Like Graham, I have never heard of it. 

What was the trader trying to sell you?

Believe it or not I was on the M1 travelling from Leeds to Sheffield to deliver my car to a trader was was buying it off me for his stock.    He still bought it at the original agreed price  after I told him I had heard this low sound at 70-80mph.   Absolutely nothing up to 70mph.  He said his close friend at Lexus Sheffield, the after sales manager,  had mentioned this issue  to him previously saying some customers notice it and some don't.   With the audio on most times I can't say I did myself but noticed it on the very day I was selling my 460.    I'm now looking for a Lexus GS300h Premier  (Hen's Teeth)  which have a few toys but extremely low road tax and better economy which is why I am changing cars. Enjoyed my 460  over the 3 years I had it.  Best car to date.
