2014 Transmission whine and clunk
New to me 2014 LS 460 F Sport (CPO - 25K miles)
On my cross country drive from East coast to California - two things became apparent.
1 - Transmission whine
I found the posts about it - and have the TSB describing a remedy.
My question is...
The whine is evident at all speeds under load. the TSB is specific to 0-40 mph.
Mine is whining at higher speeds as well . under load you can hear it.
(Like one of the posts put it - I heard it and now I can't un-hear it!)
And....
On two occasions on my trip back (I've had the car for a week...) when decelerating (coasting / braking) from freeway cruising speeds onto an off ramp - there was a hard clunk / knock - very evident as the tranny downshifted.
It was NOT subtle at all.
I can't reproduce the problem - so I'm reaching out and trying to see if this is something others have had to deal with.
Thanks ahead of time.!

I've only had the car for about a week - picked it up in Florida and drove back to California - so I haven't taken it to my dealer yet.
As for the whine - I noticed it the third day - I was passenger - had unbuckle the seatbelt to lean down and pick something up when at a stop - when we accelerated .... OMG! It sounded like a jet turbine!
I really was taken aback. - Far more noticable when you bring your ear down to the center column.
Once I had that frequency in my brain - I heard it ALL THE TIME!
And I can distinctly hear it at higher speeds when under load - accelerating.
It is harder to hear with the added ambient noise at speed - but it be there.
It's the hard clunk while slowing / breaking / down shifting that I am really curious about - whether others have had the same hard noise.

I cant say I've heard more than two occasions where people have complained about a tranny pump whine. I will say that there are lots of cars driving around that have it and it doesn't really damage anything. But if you can hear it, I can see why it would bother you.
Personally id just sell the car, you hear it, it bothers you. Let's say they replace the tranny under warranty, are you going to hear it again? Like you said you've become kind of sensitive to it, you heard it when your ear was down low to the floor. Now you hear it all the time. You'll probably hear a little something with a new unit because you're so intune with it. As for the clunk, I've heard it occasionally while braking, but honestly I don't hear much with these cars because they are so well sound insulated. Can't hear much of anything. You'll notice a ticking sound coming from the engine, it's the direct injection, I can't hear it because of the insulation but I can hear it when I'm outside of the car.
Id have it looked at by the dealer, if they say it's normal and it bothers you id get rid of it. I think with these cars they are so quiet that when you do hear something it can be more noticeable than with other cars. Like I'll get into other cars and all of the sudden I can hear everything, it's crazy. I'll hear the tires, the engine, the suspension, the tranny, the road. It all comes right into the cabin so it kind of becomes normal, you are accustomed to it. With the LS you hear nothing, so when you hear something? It becomes annoying.

Thanks for the suggestion - I am nearly certain (99%) it is not wheel noise but transmission -
It is RWD and under original warranty until 10 / 18...also it is CPO
I'll be taking into my dealer soon.

There's a TSB for the transmission whine (2013-2015). It involves replacing the engine/transmission mount/isolator. Take it to the dealer and ask them about this. Have them check out any rough shifting while its there.
Note that TSBs are performed under the original 4/50 warranty only - NOT the CPO or any extended Lexus warranty.

Update us when you hear something. I just picked up a 2013 Fsport and one thing i noticed is it is definitely more noisy than non-F-Sport cars. I kinda figured that was normal since they put the intake resonators on them and whatnot. Frankly I kinda like it, but if its not supposed to make that noise I would probably want to do something about it.

That is GOOD to know!
Many Thanks!

Hi XFEA
I am experiencing the same problem on my 2014 RWD 460 and told the dealer about it at my first CPO service. They said they hooked the tranny up to the computer and everything was normal. I just now found the TSB, and your post, so I was wondering if you could give a quick update on your repair experience.
Thanks

No way they have that!
Lexus definitely doesn't have that... you know they're about 5 years behind on in-car technology (no digital speed-o, really!?!) lol. But I don't want to digress into that discussion.
Thanks so much for your reply Keith. I'd really like to hear people's experience on this Tranny issue, because RNR ;-) —Ride, Noise, and Reliability— are the real reasons we went with Lexus (not bells and whistles and gadgets). I would like to know what to expect and how to deal with my service rep when I go in for my 65k service in a week or 2.
